Himanshi Yadav, Radhey Shyam Sharma, Rajeev Singh. Immunotoxicity of radiofrequency radiation. Environmental Pollution. 2022. doi: 10.1016/j.envpol.2022.119793.

Highlights

• Drastic growth in communication technologies increased RFR exposure in environment

• Recent evidences show close relation among radiation sensitivity and immune effects

• An intracellular signaling cascade responsible for RFR action on immune system is suggested

• A better understanding of RFR linked cell effects might help radiation protection

• Urgent need to recognize probable hazards of using RFR emitting devices in excess

Abstract

Growing evidence recommends that radiofrequency radiations might be a new type of environmental pollutant. The consequences of RFR on the human immune system have gained considerable interest in recent years, not only to examine probable negative effects on health but also to understand if RFR can modulate the immune response positively. Although several studies have been published on the immune effects of RFR but no satisfactory agreement has been reached. Hence this review aims to evaluate the RFR modulating impacts on particular immune cells contributing to various innate or adaptive immune responses. In view of existing pieces of evidence, we have suggested an intracellular signaling cascade responsible for RFR action. The bio-effects of RFR on immune cell morphology, viability, proliferation, genome integrity, and immune functions such as ROS, cytokine secretion, phagocytosis, apoptosis, etc. are discussed. The majority of existing evidence point toward the possible shifts in the activity, number, and/or function of immunocompetent cells, but the outcome of several studies is still contradictory and needs further studies to reach a conclusion. Also, the direct association of experimental studies to human risks might not be helpful as exposure parameters vary in real life. On the basis of recent available literature, we suggest that special experiments should be designed to test each particular signal utilized in communication technologies to rule out the hypothesis that longer exposure to RFR emitting devices would affect the immunity by inducing genotoxic effects in human immune cells.

Concluding remarks

I. Till date, the bulk of available research articles remarkably indicated the RFR-induced changes in innate and adaptive immune responses. The morphological and physiological modulations in the immune cells were reported such as variation in viability, gene and protein expression, generation of ROS, induction of DNA damage, stimulation of inflammatory markers, altered normal immune functions and eventually provoking inflammatory reactions, chronic allergic reactions, autoimmune responses leading to damaged tissues and organs.

II. The oxidative stress via causing free radical damage to DNA appears to be the main mechanism for RFR action.

III. Many RFR studies showed conflicting conclusions because of the scarcity of subjects, variations in distance from the radiation source, exposure time, RFR frequency, mode of modulation, SAR, or power density used in various studies. Furthermore, studies even with the same experimental design showed varied responses in different types of cells.

IV. On the other hand, the findings from in vitro and in vivo studies on RFR should not be directly linked to human mobile phone usage as the duration and level of exposure to radiofrequency radiation were much higher in experimental studies as compared to what people experience with even high cell phone usage.

V. Collectively, in view of discussed limitations, the available research studies might not be enough to understand the RFR effect on the immune system.

VI. Since, the controversies exist in the recent literature on the effects of RFR on immune cell physiology, substantially more coordinated and detailed studies are needed to set up a definitive trend in RFR effects on immune cells. Such studies are also required to address the important issues of safety for the usage of technologies like cell phones and wireless equipment that are used increasingly in our everyday lives and to revise the current EMF public safety limits.


Immunity and Electromagnetic Fields (Review paper)

Piotr Piszczek, Karolina Wójcik-Piotrowicz, Krzysztof Gil, Jolanta Kaszuba-Zwoińska. Immunity and electromagnetic fields. Environ Res. 2021 Jun 11;111505. doi: 10.1016/j.envres.2021.111505.

Abstract

Despite many studies, the question about the positive or negative influence of electromagnetic fields (EMF) on living organisms still remains an unresolved issue. To date, the results are inconsistent and hardly comparable between different laboratories. The observed bio-effects are dependent not only on the applied EMF itself, but on many other factors such as the model system tested or environmental ones. In an organism, the role of the defense system against external stressors is played by the immune system consisting of various cell types. The immune cells are engaged in many physiological processes and responsible for the proper functioning of the whole organism. Any factor with an ability to cause immunomodulatory effects may weaken or enhance the response of the immune system. This review is focused on a wide range electromagnetic fields as a possible external factor which may modulate the innate and/or adaptive immunity. Considering the existing databases, we have compiled the bio-effects evoked by EMF in particular immune cell types involved in different types of immune response, with the common mechanistic models and mostly activated intracellular signaling cascade pathways.


Highlights

• Immune system cells are influenced by exposure to EMFs.
• EMFs might modulate effector activities of immune response.
• Bio-effectiveness is related to the frequency range of EMFs and cell types.
• Cellular changes might be enhanced by synergic effects of EMFs and other stressors.

Excerpts 

"The theoretical approaches most frequently cited in the literature are based on concepts such as resonant absorption (Blanchard and Blackman, 1994; Engström, 1996), effects on bio-molecules with magnetic properties (Kirschvink, 1992; Pall, 2013; Yamagashi et al., 1992), ionic transport (Gartzke and Lange, 2002; Panagopoulos et al., 2002) and modulation of Ca2+-dependent signaling pathways (Liboff et al., 2003; Pilla, 2012), radical pair mechanism (RPM), and reactive oxygen species (ROS) chemistry (Eveson et al., 2000; Mattsson and Simkó, 2014; Tang et al., 2016)....

Conclusions

Currently it is extremely difficult to select an intracellular mechanism that could play a dominant role in viability and/or effector activities modulation of various types of immune cells under EMF exposure in a wide range of parameters. The large number of results obtained for various EMF parameters and experimental conditions do not allow for a simple comparison of findings across different laboratories. Nevertheless, most of the studies are in agreement that:

(i) there is no generally accepted physical and/or biological mechanism of EMF action independently on type of the studies (i.e., in vivo/in vitro);

(ii) there is lack of conclusive evidence of EMF genotoxic effects;

(iii) findings concerning intracellular effects such as EMF-induced modulation of: gene expression, heat-shock proteins level, surface of cell membrane and cell morphology, signal transduction pathways, ions homeostasis and level of ROS [reactive oxygen species] cannot be excluded;

(iv) significant bio-effects are noticed for simultaneous EMF exposure with other cell stimuli (synergic effects);

(v) the response of various immune cells differs in an EMF type-dependent manner;

(vi) multidirectional research on immune cell cultures are certainly needed to be continued to understand potential risk of EMF exposure;

(vii) the influence of EMF on the innate immunity seems to be interesting issue in the context of aging process (Pawelec et al., 2020).

In summary, EMF seem to be a promising tool for modulation of various immune cell signaling pathways and immune system responses. Moreover, the studies concerning the action of electromagnetic fields alone or combined with medicaments are embedded in the mainstream of interests of EMF-related research in medicine and health care."

The following paper on the effects on the immune system from exposure to radio frequency radiation consists of excerpts from a research review published in a peer-reviewed journal in 2013 by Dr. Stanislaw Szmigielski. 

Reaction of the Immune System to Low-Level RF/MW Exposures

Szmigielski S. Reaction of the immune system to low-level RF/MW exposures. Science of the Total Environment. 2013 Jun 1; 454-455:393-400. doi: 10.1016/j.scitotenv.2013.03.034.

Abstract

Radiofrequency (RF) and microwave (MW) radiation have been used in the modern world for many years. The rapidly increasing use of cellular phones in recent years has seen increased interest in relation to the possible health effects of exposure to RF/MW radiation. In 2011 a group of international experts organized by the IARC (International Agency for Research on Cancer in Lyon) concluded that RF/MW radiations should be listed as a possible carcinogen (group 2B) for humans. The incomplete knowledge of RF/MW-related cancer risks has initiated searches for biological indicators sensitive enough to measure the "weak biological influence" of RF/MWs. One of the main candidates is the immune system, which is able to react in a measurable way to discrete environmental stimuli.

In this review, the impacts of weak RF/MW fields, including cell phone radiation, on various immune functions, both in vitro [cell culture studies] and in vivo [live animal studies], are discussed. The bulk of available evidence clearly indicates that various shifts in the number and/or activity of immunocompetent cells [cells that can develop an immune response] are possible, however the results are inconsistent. For example, a number of lymphocyte [small white blood cells especially found in the lymphatic system] functions have been found to be enhanced and weakened within single experiments based on exposure to similar intensities of MW radiation.

Certain premises exist which indicate that, in general, short-term exposure to weak MW radiation may temporarily stimulate certain humoral* or cellular immune functions, while prolonged irradiation inhibits the same functions.


Excerpts

“Recently, Jauchem (2008) reviewed the effects of RF/MW radiation on the immune system and concluded that although both positive and negative findings were reported in some studies, in a majority of instances no significant health effects were found. However, most studies had some methodological limitations. Some changes in immunoglobulin levels and in peripheral blood lymphocytes were reported in different studies of radar and radio/television-transmission workers (Moszczyński et al., 1999).”

Immunotropic effects of RF/MW exposure in in vitro studies

“In summary, it may be concluded that non-thermal intensities of RF/MW radiation may exert certain measurable effects and shifts in physiology of immunocompetent cells, however these effects appear to be weak, inconsistent and difficult to replicate. Among other stress reactions, induction of heat-shock proteins, altered reaction of lymphocytes to mitogens, weaken phagocytosis and/or bactericidal activity of macrophages were reported after in vitro exposure of isolated cells to arbitrarily chosen conditions of the exposure (frequency and modulation of the RF/MW radiation, power density, time and schedule of exposure, etc.).

From studies performed in our laboratories (Dąbrowski et al., 2003; Stankiewicz et al., 2006, 2010) it may be concluded that in vitro effects of non-thermal RF/MWs cannot be revealed using basic tests for assessment of function of immunocompetent cells (including typical microculture of lymphocytes with mitogen stimulation) and finer techniques (e.g., immunogenic activity of monocytes (LM index), T-cell suppressive activity (SAT index) or release of cytokines in microcultures of PBMC) are required to study the effects of RF/MW exposures. Nevertheless, nothing can be concluded on thresholds of the above phenomena, their mechanisms or relevance to health risks. None of the above discussed studies provides data which can be directly or indirectly linked to cancer development (Table 1).”

Effects of in vivo RF/MW exposures on function of the immune system

“In summary, studies of immune reactions in animals exposed to MWs provide controversial results with some papers reporting no measurable response, while in others positive results were obtained. The available bulk of evidence from numerous experimental studies in vivo aimed to assess the effects of short-term and prolonged low-level MW exposure on function and status of the immune system clearly indicates that various shifts in number and/or activity of immunocompetent cells are possible. However, the results are incoherent; the same functions of lymphocytes are reported to be weaken[ed] or enhanced in single experiments with MW exposures at similar intensities and radiation parameters. There exist premises that in general, short-term exposure to weak MWs may temporarily stimulate certain humoral or cellular immune functions, while prolonged irradiation inhibits the same functions (Grigoriev et al., 2010). There exist papers which report changes in NK [natural killer] cell activity or TNF** release in MW-exposed animals, but clinical relevance or relation to carcinogenicity of these findings is doubtful.”

Dr. Szmigielski signed the Catania Resolution in 2002:

The Catania Resolution

According to several reports, a group of scientists issued a statement on EMF at a meeting in September.

They were attending the international conference “State of the Research on Electromagnetic Fields—Scientific and Legal Issues,” organized by ISPESL, the University of Vienna, and the City of Catania. ISPESL is a technical-scientific branch of the National Health Service that advises industry on protection of occupational health and well-being in the workplace. In Catania, Italy, on Sept. 13 and 14, 2002, they agreed to the following:

Epidemiological and in vivo and in vitro experimental evidence demonstrates the existence for electromagnetic field (EMF) induced effects, some of which can be adverse to health.

We take exception to arguments suggesting that weak (low intensity) EMF cannot interact with tissue.

There are plausible mechanistic explanations for EMF-induced effects which occur below present ICNIRP and IEEE guidelines and exposure recommendations by the European Union.

The weight of evidence calls for preventive strategies based on the precautionary principle. At times the precautionary principle may involve prudent avoidance and prudent use.

We are aware that there are gaps in knowledge on biological and physical effects, and health risks related to EMF, which require additional independent research.

The undersigned scientists agree to establish an international scientific commission to promote research for the protection of public health from EMF and to develop the scientific basis and strategies for assessment, prevention, management and communication of risk, based on the precautionary principle.   https://www.bems.org/node/824

Cell Tower Health Effects

Federal regulations protect the public only from the thermal (i.e., heating) risk due to short-term exposure to high intensity, cell tower radiation. The Federal radio frequency exposure limits ignore the preponderance of peer-reviewed studies that has found harmful bio-effects from exposure to non-thermal levels of cell phone radiation.
The Telecommunications Act of 1996 does not allow communities to stop the siting of cell towers for environmental or health reasons as long they comply with the weak radio frequency exposure limits established by the Federal Communications Commission (FCC).
The public needs to organize and change the Federal law to protect public health and wildlife from exposure to microwave radiation emitted by mobile phone base stations.

As of February 6, 2021, www.antennasearch.com, an industry website, reported 803,000 cell towers and 2.1 million cell antennas in the United States. Texas has the most cell towers (80,300), and California has the most cell antennas (151,000). We cannot verify the accuracy of these data because the FCC only collects data on certain types of cell towers. 

Following are some resources regarding the health effects of exposure to cell tower radiation.

Evidence for a health risk by RF on humans living around mobile phone base stations

Balmori, A. Evidence for a health risk by RF on humans living around mobile phone base stations: From radiofrequency sickness to cancer. Environmental Research (2022), doi: 10.1016/j.envres.2022.113851.

Abstract

The objective of this work was to perform a complete review of the existing scientific literature to update the knowledge on the effects of base station antennas on humans. Studies performed in real urban conditions, with mobile phone base stations situated close to apartments, were selected. Overall results of this review show three types of effects by base station antennas on the health of people: radiofrequency sickness (RS), cancer (C) and changes in biochemical parameters (CBP). Considering all the studies reviewed globally (n=38), 73.6% (28/38) showed effects: 73.9% (17/23) for radiofrequency sickness, 76.9% (10/13) for cancer and 75.0% (6/8) for changes in biochemical parameters. Furthermore, studies that did not meet the strict conditions to be included in this review provided important supplementary evidence. The existence of similar effects from studies by different sources (but with RF [radio frequency radiation] of similar characteristics), such as radar, radio and television antennas, wireless smart meters and laboratory studies, reinforce the conclusions of this review. Of special importance are the studies performed on animals or trees near base station antennas that cannot be aware of their proximity and to which psychosomatic effects can never be attributed.

Excerpts

Introduction: During the last few decades, hundreds of thousands of mobile phone base stations and other types of wireless communications antennas have been installed around the world, in cities and in nature, including protected natural areas, in addition to pre-existing antennas (television, radio broadcasting, radar, etc.). Only the aesthetic aspects or urban regulations have been generally considered in this deployment, while the biological, environmental and health impacts of the associated non-ionizing electromagnetic radiation emissions have not been assessed so far. Therefore, the effects on humans living around these anthropogenic electromagnetic field sources (antennas) have not been considered.

In France, there is a significant contribution of mobile phone base stations in the exposure to radiofrequency electromagnetic fields (RF-EMF) of urban citizens living nearby (De Giudici et al., 2021). Some studies from India indicate that more than 15% of people have levels of EMF strength above 12 V/m due to their proximity to antennas (Premlal and Eldhose, 2017). Exposure estimates have shown that RF-EMF from mobile telephone systems is stronger in urban than in rural areas. For instance, in Sweden the levels of RF radiation have increased considerably in recent years, both outdoor and indoor, due to new telecommunication technologies, and the median power density measured for RF fields between 30 MHz and 3 GHz was 16 μW/m2 in rural areas, 270 μW/m2 in urban areas and 2400 μW/m2 in city areas (Hardell et al., 2018). Total exposure varies not only between urban and rural areas but also, depending on residential characteristics, between different floors of a building, with a tendency for building exposure to increase at higher floors (Breckenkamp et al., 2012).

Over the past five decades, and more intensively since the beginning of this century, many studies and several reviews have been published on the effects of anthropogenic electromagnetic radiation on humans living around the antennas. The first studies were carried out with radio and television antennas, investigating increases in cancer and leukaemia (Milham, 1988; Maskarinec et al., 1994; Hocking et al., 1996; Dolk et al., 1997a, 1997b; Michelozzi et al., 1998; Altpeter et al., 2000), as well as around radars (Kolodynski and Kolodynska, 1996; Goldsmith, 1997).

Regarding base station antennas, there are scientific discrepancies in their effects: some studies concluded that there are no health-related effects (e.g. Augner and Hacker, 2009; Blettner et al., 2009; Röösli et al., 2010; Baliatsas et al., 2016) whereas others found increases in cancer and other health problems in humans living around antennas (e.g. Santini et al., 2002; Navarro et al., 2003; Bortkiewicz et al., 2004; Eger et al., 2004; Wolf and Wolf, 2004; Abdel-Rassoul et al., 2007; Khurana et al., 2010; Dode et al., 2011; Shinjyo and Shinjyo, 2014; Gandhi et al., 2015; López et al., 2021; Rodrigues et al., 2021). There is a specific symptomatology linked to radar and RF exposure at low levels, characterized by functional disturbances of the central nervous system (headache, sleep disturbance, discomfort, irritability, depression, memory loss, dizziness, fatigue, nausea, appetite loss, difficulty in concentration, dizziness, etc.), that has been termed ‘RF sickness’ (Lilienfeld et al., 1978; Johnson Lyakouris, 1998; Navarro et al., 2003).


Methods: Only studies performed in real urban conditions, with mobile phone base stations situated close to apartments, were selected. Studies conducted in larger regions with numerous antennas, based on surveys and geographic data, were also included.

Results: The studies that met the selected criteria are presented in chronological order in Table 1, catalogued as Y/N depending on whether or not they found effects. The selected studies cover three types of effects: radiofrequency sickness (RS) (according to Lilienfeld et al., 1978; Johnson Lyakouris, 1998), cancer (C) and changes in biochemical parameters (CBP). Table 1 also includes the authors, year and country, antenna type, study design, diseases and symptoms found/not found and the main conclusions of each study.

Discussion: Considering all the selected studies (n=38), 73.6% (28/38) showed effects: 73.9% (17/23) for radiofrequency sickness, 76.9% (10/13) for cancer and 75.0% (6/8) for changes in biochemical parameters (Figure 1). Therefore, most of the studies carried by research groups from twenty different countries reach the same conclusions.

For the reasons previously explained, the following studies (n=85) were not considered in this review, even though the conclusions of some of these studies will be discussed later due to their importance regarding the similarities of the electromagnetic radiation types involved and the effects found in many cases....

The results of this review show three types of effects by base station antennas on the health of humans: radiofrequency sickness, cancer and changes in biochemical parameters (Fig. 1). From among all these studies, most of them found effects (73.6%). Thus, despite some limitations and differences in study design, statistical measures, risk estimates and exposure categories (Khurana et al., 2010), together they provide a consistent view of the effects on the health of people living in the vicinity of base station antennas.

The International Commission on Non-Ionizing Radiation Protection (ICNIRP) is a private organization that issues exposure guidelines that are then adopted by governments, but it has been accused of having conflicts of interest (Hardell and Carlberg, 2020; Hardell et al., 2021). The ICNIRP (2010, 2020) limits are thousands of times above the levels where effects are recorded for both extremely low frequency and RF man-made EMF and account only for thermal effects, whereas the vast majority of recorded effects are non-thermal. These existing guidelines for public health protection only consider the effects of acute intense (thermal) exposures and do not protect from lower level long-term exposures (Israel et al., 2011; Yakimenko et al., 2011; Blank et al., 2015; Starkey, 2016; Belpomme and Irigaray, 2022). The exposure duration is crucial to assess the induced effects. 

Conclusion:  In the current circumstances, it seems that the scientific experts in the field are very clear about the serious problems we are facing and have expressed this through important appeals (Blank et al., 2015; Hardell and Nyberg, 2020). However, the media, the responsible organizations (World Health Organization, 2015) and the governments are not transmitting this crucial information to the population, who remain uninformed. For these reasons, the current situation will probably end in a crisis not only for health but also for the technology itself, as it is unsustainable and harmful to the environment and the people.

What is the radiation before 5G? A correlation study between measurements in situ and in real time and epidemiological indicators in Vallecas, Madrid

Isabel López, Nazario Félix, Marco Rivera, Adrián Alonso, Ceferino Maestú. What is the radiation before 5G? A correlation study between measurements in situ and in real time and epidemiological indicators in Vallecas, Madrid. Environ Res. 2021 Mar;194:110734. doi: 10.1016/j.envres.2021.110734.

Abstract

Background: Exposure of the general population to electromagnetic radiation emitted by mobile phone base stations is one of the greater concerns of residents affected by the proximity of these structures due to the possible relationship between radiated levels and health indicators.

Objectives: This study aimed to find a possible relationship between some health indicators and electromagnetic radiation measurements.

Methods: A total of 268 surveys, own design, were completed by residents of a Madrid neighborhood surrounded by nine telephone antennas, and 105 measurements of electromagnetic radiation were taken with a spectrum analyzer and an isotropic antenna, in situ and in real-time, both outside and inside the houses.

Results: It was shown statistically significant p-values in headaches presence (p = 0.010), nightmares (p = 0.001), headache intensity (p < 0.001), dizziness frequency (p = 0.011), instability episodes frequency (p = 0.026), number of hours that one person sleeps per day (p < 0.001) and three of nine parameters studied from tiredness. Concerning cancer, there are 5.6% of cancer cases in the study population, a percentage 10 times higher than that of the total Spanish population.

Discussion: People who are exposed to higher radiation values present more severe headaches, dizziness and nightmares. Moreover, they sleep fewer hours.

https://pubmed.ncbi.nlm.nih.gov/33434609/

Excerpts

Highlights

• People who are exposed to higher radiation values present more severe headaches, dizziness and nightmares.
• The methodology for obtaining electromagnetic radiation measurements should be reviewed.
• The population continues to receive radiation peaks in distances greater than 200 meters, no one is free from exposure.

Conclusion

In conclusion, the data obtained shows that there is a relationship between the power density of radiation that a person receives at home every day and the presence of headaches, as well as the presence of sleep disorders. People who receive higher doses of radiation sleep less hours and have nightmares at night. In addition, these people suffer from headaches with greater intensity and are more prone to dizziness. In this study, indicators like fainting episodes, presence of tachycardias or instability cannot be related. No conclusive results were found for fatigue, since, out of nine parameters studied, only a statistically significant relationship was found in three of them. The study of how electromagnetic fields affect health, should not only be done in relation to cancer, but also health indicators related to day to day. The methodology for obtaining electromagnetic radiation measurements should be reviewed, the averaged radiation measurements that are described in the CENELEC standard are not the most appropriate, they should be carried out in a narrow band and with maximum peak measurements.

The measured intensity depends fundamentally on the direction of the fundamental radiation beam and not so much on the distance to the antenna. In the beam direction, differences are found in the presence of pathologies with respect to distances, when these are greater than 200 meters. Even at this distance, the population continues to receive radiation peaks, so that no one is free from exposure to these radiation sources.

The need for this study is related to the situation before 5G in terms of electromagnetic radiation rates. This study may be compared with the new radiant procedures that will be adopted in a short time.

Research on Cell Tower Radiation
and Children and Adolescents’ Health

May 31, 2019

The following seven studies were found in a search of the EMF-Portal database for mobile phone base station (i.e., cell towers) and children or adolescents. For additional studies of cell tower health effects see http://bit.ly/celltowerEMR.

Summary of Results

Meo et al (2019): Higher exposure to cell tower RFR was associated with delayed fine and gross motor skills, spatial working memory, and attention among adolescents compared to students exposed to lower levels of cell tower RFR. (13-16 years of age)

Durusoy et al (2017): An association was found between mobile phone use and headache, concentration difficulties, fatigue, sleep disturbances and warming of the ear showing a dose-response. Limited associations were found between vicinity to cell towers and some general symptoms; however, no association was found with school RFR levels. (high school students)

Schoeni et al (2016): In the cohort approach, an association was found between modelled RFR exposure from fixed site transmitters and tiredness and concentration difficulties in adolescents. (12-17 years of age)

Guxens et al (2016): Higher residential RFR exposure from cell towers and presence of indoor sources was associated with improved inhibitory control and cognitive flexibility whereas higher personal cordless phone use was associated with reduced inhibitory control and cognitive flexibility. Higher residential cell tower exposure was associated with reduced visuomotor coordination whereas improved visuomotor coordination was associated with residential indoor sources of RFR and higher personal cell phone use. (5-6 years of age)

Calvente et al (2016): Children living in higher RFR exposure areas had lower verbal expression and comprehension scores and more internalizing and total problems, and were more likely to have obsessive-compulsive and post-traumatic stress disorders, in comparison to those living in areas with lower RFR exposure. These associations were stronger when maximum RFR exposures were examined as opposed to average exposures. (9-11 years of age)

Meo et al (2015): Students exposed to higher cell tower RFR had a significantly greater risk of type 2 diabetes mellitus (p = 0.016) relative to others exposed to lower cell tower RFR. High cell tower RFR was associated with elevated levels of HbA1c and risk of type 2 diabetes mellitus. (12-17 years of age)

Huss et al (2015): Children exposed to higher levels of cell tower RFR had worse sleep duration but fewer sleep disruptions. (7 years of age)

Impact of radiofrequency radiation on DNA damage and antioxidants in peripheral blood lymphocytes of humans residing near cell towers

Zothansiama, Zosangzuali M, Lalramdinpuii M, Jagetia GC. Impact of radiofrequency radiation on DNA damage and antioxidants in peripheral blood lymphocytes of humans residing in the vicinity of mobile phone base stations. Electromagn Biol Med. 2017 Aug 4:1-11. doi: 10.1080/15368378.2017.1350584.

Abstract

Radiofrequency radiations (RFRs) emitted by mobile phone base stations have raised concerns on its adverse impact on humans residing in the vicinity of mobile phone base stations. Therefore, the present study was envisaged to evaluate the effect of RFR on the DNA damage and antioxidant status in cultured human peripheral blood lymphocytes (HPBLs) of individuals residing in the vicinity of mobile phone base stations and comparing it with healthy controls.

The study groups were matched on various demographic data including age, gender, dietary pattern, smoking habit, alcohol consumption, duration of mobile phone use and average daily mobile phone use.

The RF power density of the exposed individuals was significantly higher (p < 0.0001) when compared to the control group. The HPBLs were cultured and the DNA damage was assessed by cytokinesis blocked micronucleus (MN) assay in the binucleate lymphocytes. The analyses of data from the exposed group (n = 40), residing within a perimeter of 80 meters of mobile base stations, showed significantly (p < 0.0001) higher frequency of micronuclei (MN) when compared to the control group, residing 300 meters away from the mobile base station/s.

The analysis of various antioxidants in the plasma of exposed individuals revealed a significant attrition in glutathione (GSH) concentration (p < 0.01), activities of catalase (CAT) (p < 0.001) and superoxide dismutase (SOD) (p < 0.001) and rise in lipid peroxidation (LOO) when compared to controls. Multiple linear regression analyses revealed a significant association among reduced GSH concentration (p < 0.05), CAT (p < 0.001) and SOD (p < 0.001) activities and elevated MN frequency (p < 0.001) and LOO (p < 0.001) with increasing RF power density.


My note

All of the recorded RFR power density values in this study were well below the Federal Communication Commission’s maximum permissible exposure limits in the U.S. for the general population. These limits are are 6,000 mW/m2 [milliwatts per square meter] for 900 MHz and 10,000 mW/m2 for 1800 MHz radiofrequency radiation. In contrast, the highest recorded value in this study was 7.52 mW/m2 of RFR. The “exposed individuals” who resided within 80 meters of a cell antenna received an average of 5.00 mW/m2 of RFR in their bedrooms.

RFR may change the fidelity of DNA as the increased incidence of cancer has been reported among those residing near mobile phone base stations (Abdel-Rassonl et al., 2007; Bortkiewicz et al., 2004; Cherry, 2000; Eger et al., 2004; Hardell et al., 1999; Hutter et al., 2006; Wolf and Wolf, 2004). RFR emitted frommobile base stations is also reported to increase the DNA strand breaks in lymphocytes of mobile phone users and individuals residing in the vicinity of a mobile base station/s (Gandhi and Anita, 2005; Gandhi et al., 2014). Exposure of human fibroblasts and rat granulosa cells to RFR (1800 MHz, SAR 1.2 or 2 W/kg) has been reported to induce DNA single- and double-strands breaks (Diem et al., 2005). Irreversible DNA damage was also reported in cultured human lens epithelial cells exposed to microwave generated by mobile phones (Sun et al., 2006). The adverse health effects of RFR are still debatable as many studies indicated above have found a positive correlation between the DNA damage and RFR exposure; however, several studies reported no significant effect of RFR on DNA strand breaks and micronuclei formation in different study systems (Li et al., 2001; Tice et al., 2002; McNamee et al., 2003;Maes et al., 2006). The potential genotoxicity of RFR emitted by mobile phone base stations can be determined by micronucleus (MN) assay, which is an effective tool to evaluate the genotoxic or clastogenic effects of physical and chemical agents. This technique has also been used to quantify the frequencies of radiation-induced MN in human peripheral blood lymphocytes (HPBLs) (Fenech and Morley, 1985; Jagetia and Venkatesha, 2005; Prosser et al., 1988; Yildirim et al., 2010).

Six mobile phone base stations, operating in the frequency range of 900 MHz (N = 2) and1800MHz (N = 4), erected in the thickly populated areas of Aizawl city were selected for the present study… The power output of all the base stations is 20 W, with their primary beam emitting radiation at an angle of 20°. Power density measurements (using HF-60105V4, Germany) were carried out in the bedroom of each participant where they spent most of the time and hence have the longest constant level of electromagnetic field exposure. Power density measurement was carried out three times (morning, midday and evening), and the average was calculated for each residence around each base station. The main purpose of the measurement of power density was to ensure that RFR emission from each site did not exceed the safe public limits and to determine any difference in power density between selected households that were close to (within 80 m) and far (>300 m) from the mobile phone base stations. The safety limits for public exposure from mobile phone base stations are 0.45 W/m2 for 900 MHz and 0.92 W/m2 for 1800 MHz frequency as per Department of Telecommunications, Ministry of Communications, Government of India, New Delhi guidelines (DoT, 2012).

… some residences are located horizontally with the top of the towers from which RFR are emitted, making it possible to get an exposure at a short distance of 1–20 m, despite being erected on the rooftop or in the ground. A minimum of two individuals were sampled from each household and at least five individuals were sampled around each mobile base station. Individuals sampled around each base station were matched for their age and gender (Table 1). The exposed group consisted of 40 healthy individuals who fulfilled the inclusion criteria of being above 18 years of age and residing in the vicinity of mobile phone base stations (within 80 m radius). The control group comprised of 40 healthy individuals matched for age and gender who had been living at least 300 m away from any mobile phone base stations…. Sampling was also done only from those residences who did not use microwave oven for cooking, Wifi devices and any other major source of electromagnetic field as they are known to cause adverse effects (Atasoy et al., 2013; Avendaño et al., 2012).

The groups matched for most of the demographic data such as age, gender, dietary pattern, smoking habit, alcohol consumption, mobile phone usage, duration of mobile phone use and average daily mobile phone use (Table 2). A highly significant variation (p < 0.0001) was observed for the distance of household from the base station (40.10 ± 3.02 vs. 403.17 ± 7.98 in m) between exposed and control groups.

The RF power density of the exposed group (2.80–7.52 mW/m2; average 5.002 ± 0.182 mW/ m2) was significantly higher (p < 0.0001) when compared to the control group (0.014–0.065 mW/m2; average 0.035 ± 0.002 mW/m2). The highest power density was recorded at a distance of 1–20 m (6.44 ± 0.31 mW/m2), which is significantly higher (p < 0.0001) than those at a distance of 21–40 m (4.79 ± 0.33), 41–60 m (4.48 ± 0.22) and 61–80 m (4.61 ± 0.10).

The highest measured power density was 7.52mW/m2. Most of the measured values close to base stations (Table 1) are higher than that of the safe limits recommended by Bioinitiative Report 2012 (0.5mW/m2), Salzburg resolution 2000 (1 mW/m2) and EU (STOA) 2001 (0.1 mW/m2). However, all the recorded values were well below the current ICNIRP safe level (4700 mW/m2) and the current Indian Standard (450 mW/m2).

The exact mechanism of action of RFR in micronuclei induction and reduced antioxidant status is not apparent. The possible putative mechanism of generation of DNA damage may be the production of endogenous free radicals due to continuous exposure. RFR has been reported to produce different free radicals earlier (Avci et al., 2009; Burlaka et al., 2013; Barcal et al., 2014; Kazemi et al., 2015). Cells possess a number of compensatory mechanisms to deal with ROS and its effects. Among these are the induction of antioxidant proteins such as GSH, SOD and CAT. Enzymatic antioxidant systems function by direct or sequential removal of ROS, thereby terminating their activities. An imbalance between the oxidative forces and antioxidant defense systems causes oxidative injury, which has been implicated in various diseases, such as cancer, neurological disorders, atherosclerosis, diabetes, liver cirrhosis, asthma, hypertension and ischemia (Andreadis et al., 2003; Comhair et al., 2005; Dhalla et al., 2000; Finkel and Holbrook, 2000; Kasparova et al., 2005; Sayre et al., 2001; Sohal et al., 2002). Because of the significant decrease in endogenous antioxidants and increased LOO among the exposed group, the extra burden of free radicals is unlikely to get neutralized, and these surplus ROS may react with important cellular macromolecules including DNA forming either DNA adducts or stand breaks, which may be later expressed as micronuclei once the cell decides to divide. The decline in the antioxidant status may be also due to the suppressed activity of Nrf2 transcription factor which is involved in maintaining the antioxidant status in the cells.

The present study has reported that [radiofrequency radiation] increased the frequency of [micronuclei] and [lipid peroxidation] and reduced [glutathione] contents, [catalase] and [superoxide dismutase] activities in the plasma of the exposed individuals. The induction of [micronuclei] may be due to the increase in free-radical production. The present study demonstrated that staying near the mobile base stations and continuous use of mobile phones damage the DNA, and it may have an adverse effect in the long run. The persistence of DNA unrepaired damage leads to genomic instability which may lead to several health disorders including the induction of cancer.

Biological effects from exposure to electromagnetic radiation emitted by
cell tower base stations and other antenna arrays

Levitt BB, Lai H. Biological effects from exposure to electromagnetic radiation emitted by cell tower base stations and other antenna arrays. Environmental Reviews.18: 369–395 (2010) doi:10.1139 /A10-018. 


Abstract

The siting of cellular phone base stations and other cellular infrastructure such as roof-mounted antenna arrays, especially in residential neighborhoods, is a contentious subject in land-use regulation. Local resistance from nearby residents and landowners is often based on fears of adverse health effects despite reassurances from telecommunications service providers that international exposure standards will be followed. 

Both anecdotal reports and some epidemiology studies have found headaches, skin rashes, sleep disturbances, depression, decreased libido, increased rates of suicide, concentration problems, dizziness, memory changes, increased risk of cancer, tremors, and other neurophysiological effects in populations near base stations. 

The objective of this paper is to review the existing studies of people living or working near cellular infrastructure and other pertinent studies that could apply to long-term, low-level radiofrequency radiation (RFR) exposures. While specific epidemiological research in this area is sparse and contradictory, and such exposures are difficult to quantify given the increasing background levels of RFR from myriad personal consumer products, some research does exist to warrant caution in infrastructure siting. Further epidemiology research that takes total ambient RFR exposures into consideration is warranted. 

Symptoms reported today may be classic microwave sickness, first described in 1978. Nonionizing electromagnetic fields are among the fastest growing forms of environmental pollution. Some extrapolations can be made from research other than epidemiology regarding biological effects from exposures at levels far below current exposure guidelines.

Excerpts

In lieu of building new cell towers, some municipalities are licensing public utility poles throughout urban areas for Wi-Fi antennas that allow wireless Internet access. These systems can require hundreds of antennas in close proximity to the population with some exposures at a lateral height where second- and third-story windows face antennas. Most of these systems are categorically excluded from regulation by the U.S. Federal Communications Commission (FCC) or oversight by government agencies because they operate below a certain power density threshold. However, power density is not the only factor determining biological effects from radiofrequency radiation (RFR).

An aesthetic emphasis is often the only perceived control of a municipality, particularly in countries like America where there is an overriding federal preemption that precludes taking the “environmental effects” of RFR into consideration in cell tower siting as stipulated in Section 704 of The Telecommunications Act of 1996 (USFCC 1996). Citizen resistance, however, is most often based on health concerns regarding the safety of RFR exposures to those who live near the infrastructure. Many citizens, especially those who claim to be hypersensitive to electromagnetic fields, state they would rather know where the antennas are and that hiding them greatly complicates society’s ability to monitor for safety.

Industry representatives try to reassure communities that facilities are many orders of magnitude below what is allowed for exposure by standards-setting boards and studies bear that out (Cooper et al. 2006Henderson and Bangay 2006Bornkessel et al. 2007). These include standards by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) used throughout Europe, Canada, and elsewhere (ICNIRP 1998). The standards currently adopted by the U.S. FCC, which uses a two-tiered system of recommendations put out by the National Council on Radiation Protection (NCRP) for civilian exposures (referred to as uncontrolled environments), and the International Electricians and Electronics Engineers (IEEE) for professional exposures (referred to as controlled environments) (U.S. FCC 1997). The U.S. may eventually adopt standards closer to ICNIRP. The current U.S. standards are more protective than ICNIRP’s in some frequency ranges so any harmonization toward the ICNIRP standards will make the U.S. limits more lenient.

All of the standards currently in place are based on RFRs ability to heat tissue, called thermal effects. A longstanding criticism, going back to the 1950s (Levitt 1995), is that such acute heating effects do not take potentially more subtle non-thermal effects into consideration. And based on the number of citizens who have tried to stop cell towers from being installed in their neighborhoods, laypeople in many countries do not find adherence to existing standards valid in addressing health concerns. Therefore, infrastructure siting does not have the confidence of the public (Levitt 1998).

The intensity of RFR decreases rapidly with the distance from the emitting source; therefore, exposure to RFR from transmission towers is often of low intensity depending on one’s proximity. But intensity is not the only factor. Living near a facility will involve long-duration exposures, sometimes for years, at many hours per day. People working at home or the infirm can experience low-level 24 h exposures. Nighttimes alone will create 8 hour continuous exposures. The current standards for both ICNIRP, IEEE and the NCRP (adopted by the U.S. FCC) are for whole-body exposures averaged over a short duration (minutes) and are based on results from short-term exposure studies, not for long-term, low-level exposures such as those experienced by people living or working near transmitting facilities. For such populations, these can be involuntary exposures, unlike cell phones where user choice is involved.

The U.S. FCC has issued guidelines for both power density and SARs. For power density, the U.S. guidelines are between 0.2–1.0 mW/cm2….

At 100–200 ft (about 30–60 meters) from a cell phone base station, a person can be exposed to a power density of 0.001 mW/cm2 (i.e., 1.0 μW/cm2)….

For the purposes of this paper, we will define low-intensity exposure to RFR of power density of 0.001 mW/cm

Many biological effects have been documented at very low intensities comparable to what the population experiences within 200 to 500 ft (60–150 m) of a cell tower, including effects that occurred in studies of cell cultures and animals after exposures to low-intensity RFR. Effects reported include: genetic, growth, and reproductive; increases in permeability of the blood–brain barrier; behavioral; molecular, cellular, and metabolic; and increases in cancer risk….

Ten years ago, there were only about a dozen studies reporting such low-intensity effects; currently, there are more than 60. This body of work cannot be ignored. These are important findings with implications for anyone living or working near a transmitting facility. However, again, most of the studies in the list are on short-term (minutes to hours) exposure to low-intensity RFR. Long-term exposure studies are sparse. In addition, we do not know if all of these reported effects occur in humans exposed to low-intensity RFR, or whether the reported effects are health hazards. Biological effects do not automatically mean adverse health effects, plus many biological effects are reversible. However, it is clear that low-intensity RFR is not biologically inert. Clearly, more needs to be learned before a presumption of safety can continue to be made regarding placement of antenna arrays near the population, as is the case today.

… The previously mentioned studies show that RFR can produce effects at much lower intensities after test animals are repeatedly exposed. This may have implications for people exposed to RFR from transmission towers for long periods of time.

The conclusion from this body of work is that effects of long-term exposure can be quite different from those of short-term exposure.
Since most studies with RFR are short-term exposure studies, it is not valid to use their results to set guidelines for long-term exposures, such as in populations living or working near cell phone base stations.
Numerous biological effects do occur after short-term exposures to low-intensity RFR but potential hazardous health effects from such exposures on humans are still not well established, despite increasing evidence as demonstrated throughout this paper. Unfortunately, not enough is known about biological effects from long-term exposures, especially as the effects of long-term exposure can be quite different from those of short-term exposure. It is the long-term, low-intensity exposures that are most common today and increasing significantly from myriad wireless products and services.
People are reporting symptoms near cell towers and in proximity to other RFR-generating sources including consumer products such as wireless computer routers and Wi-Fi systems that appear to be classic “microwave sickness syndrome,” also known as “radiofrequency radiation sickness.” First identified in the 1950s by Soviet medical researchers, symptoms included headache, fatigue, ocular dysfunction, dizziness, and sleep disorders. In Soviet medicine, clinical manifestations include dermographism, tumors, blood changes, reproductive and cardiovascular abnormalities, depression, irritability, and memory impairment, among others. The Soviet researchers noted that the syndrome is reversible in early stages but is considered lethal over time (Tolgskaya et al. 1973).

The present U.S. guidelines for RFR exposure are not up to date. The most recent IEEE and NCRP guidelines used by the U.S. FCC have not taken many pertinent recent studies into consideration because, they argue, the results of many of those studies have not been replicated and thus are not valid for standards setting. That is a specious argument. It implies that someone tried to replicate certain works but failed to do so, indicating the studies in question are unreliable. However, in most cases, no one has tried to exactly replicate the works at all.... In addition, effects of long-term exposure, modulation, and other propagation characteristics are not considered. Therefore, the current guidelines are questionable in protecting the public from possible harmful effects of RFR exposure and the U.S. FCC should take steps to update their regulations by taking all recent research into consideration without waiting for replication that may never come because of the scarcity of research funding. The ICNIRP standards are more lenient in key exposures to the population than current U.S. FCC regulations. The U.S. standards should not be “harmonized” toward more lenient allowances. The ICNIRP should become more protective instead. All standards should be biologically based, not dosimetry based as is the case today.
Exposure of the general population to RFR from wireless communication devices and transmission towers should be kept to a minimum and should follow the “As Low As Reasonably Achievable” (ALARA) principle. Some scientists, organizations, and local governments recommend very low exposure levels — so low, in fact, that many wireless industries claim they cannot function without many more antennas in a given area. However, a denser infrastructure may be impossible to attain because of citizen unwillingness to live in proximity to so many antennas. In general, the lowest regulatory standards currently in place aim to accomplish a maximum exposure of 0.02 V/m, equal to a power density of 0.0001 μW/cm2, which is in line with Salzburg, Austria’s indoor exposure value for GSM cell base stations. Other precautionary target levels aim for an outdoor cumulative exposure of 0.1 μW/cm2 for pulsed RF exposures where they affect the general population and an indoor exposure as low as 0.01 μW/cm2 (Sage and Carpenter 2009). In 2007, The BioInitiative Report, A rationale for a biologically based public exposure standard for electromagnetic fields (ELF and RF), also made this recommendation, based on the precautionary principle (Bioinitiative Report 2007).

Citizens and municipalities often ask for firm setbacks from towers to guarantee safety. There are many variables involved with safer tower siting — such as how many providers are co-located, at what frequencies they operate, the tower’s height, surrounding topographical characteristics, the presence of metal objects, and others. Hard and fast setbacks are difficult to recommend in all circumstances. Deployment of base stations should be kept as efficient as possible to avoid exposure of the public to unnecessary high levels of RFR. As a general guideline, cell base stations should not be located less than 1500 ft (500 m) from the population, and at a height of about 150 ft (50 m). Several of the papers previously cited indicate that symptoms lessen at that distance, despite the many variables involved. However, with new technologies now being added to cell towers such as Wi-Max networks, which add significantly more power density to the environment, setback recommendations can be a very unpredictable reassurance at best. New technology should be developed to reduce the energy required for effective wireless communication.

In addition, regular RFR monitoring of base stations should be considered….

 Epidemiological evidence for a health risk from cell towers
Khurana VG, Hardell L, Everaert J, Bortkiewicz A, Carlberg M, Ahonen M. Epidemiological evidence for a health risk from mobile phone base stations. Int J Occup Environ Health. 2010 Jul-Sep;16(3):263-7.

Abstract

Human populations are increasingly exposed to microwave/radiofrequency (RF) emissions from wireless communication technology, including mobile phones and their base stations. By searching PubMed, we identified a total of 10 epidemiological studies that assessed for putative health effects of mobile phone base stations. Seven of these studies explored the association between base station proximity and neurobehavioral effects and three investigated cancer. We found that eight of the 10 studies reported increased prevalence of adverse neurobehavioral symptoms or cancer in populations living at distances < 500 meters from base stations. None of the studies reported exposure above accepted international guidelines, suggesting that current guidelines may be inadequate in protecting the health of human populations. We believe that comprehensive epidemiological studies of long-term mobile phone base station exposure are urgently required to more definitively understand its health impact.
