Cell Phone Radiation Cancer Risk: What is the American Cancer Society’s Position?

The American Cancer Society (ACS) recently revised a 58-page document entitled, “Brain and Spinal Cord Tumors in Adults” and updated its website page on “Cellular Phones.”

Brain and Spinal Cord Tumors in Adults

“Brain and Spinal Cord Tumors in Adults” dismisses the potential cancer risk from using cell phones and refers readers to the ACS web site for further information:

Cell phone use
"This has been the subject of a great deal of debate in recent years. Cell phones give off radiofrequency (RF) rays, a form of energy on the electromagnetic spectrum between FM radio waves and those used in microwave ovens, radar, and satellite stations. Cell phones do not give off ionizing radiation, the type that can cause cancer by damaging the DNA inside cells. Still, there have been concerns that the phones, whose antennae are built-in and therefore are placed close to the head when being used, might somehow raise the risk of brain tumors.

Some studies have suggested a possible increased risk of brain tumors or of vestibular schwannomas with cell phone use, but most of the larger studies done so far have not found an increased risk, either overall or among specific types of tumors. Still, there are very few studies of long-term use (10 years or more), and cell phones haven’t been around long enough to determine the possible risks of lifetime use. The same is true of any possible higher risks in children, who are increasingly using cell phones. Cell phone technology also continues to change, and it’s not clear how this might affect any risk.

These risks are being studied, but it will probably be many years before firm conclusions can be made. In the meantime, for people concerned about the possible risks, there are ways to lower your exposure, such as using an earpiece to move the phone itself away from the head. For more information, see our document Cellular Phones."  (p. 15)

Can brain and spinal cord tumors in adults be prevented?

"The risk of many cancers in adults can be reduced with certain lifestyle changes (such as staying at a healthy weight or quitting smoking). But other than radiation exposure, there are no known lifestyle-related or environmental causes of brain and spinal cord tumors, so at this time there is no known way to protect against most of these tumors." (p. 17)

Cellular Phones

The ACS web site reviews the research on cell phone radiation and downplays the cancer risk from long-term exposure to cell phone and cordless phone radiation.

Although the ACS seems skeptical there is any cancer risk from cell phone use, they recommend "several things that people who are concerned about RF [radio frequency] waves can do to limit their exposure":

"Use the speaker mode on the phone or a hands-free device such as a corded or cordless earpiece. This moves the antenna away from your head, which decreases the amount of RF waves that reach the head. Corded earpieces emit virtually no RF waves (although the phone itself still emits small amounts of RF waves that can reach parts of the body if close enough, such as on the waist or in a pocket). Bluetooth® earpieces have an SAR value of around 0.001 watts/kg (less than one thousandth the SAR limit for cell phones as set by the FDA and FCC).

Texting instead of talking on the phone may be another option to reduce your exposure. But it may not be a good option in some situations, especially if you are driving. For safety reasons, it is especially important to limit or avoid the use of cell phones while driving.

Limit your (and your children’s) cell phone use. This is one of the most obvious ways to limit your exposure to RF waves from cell phones. You may want to use your cell phone only for shorter conversations, or use it only when a conventional phone is not available. Parents who are concerned about their children’s exposure can limit how much time they spend on the phone.

Some people might consider choosing a phone with a low SAR value. Different models of phones can give off different levels of RF waves. But as noted above, according to the FCC the SAR value is not always a good indicator of a person’s exposure to RF waves during normal cell phone use. One way to get information on the SAR level for a specific phone model is to visit the phone maker’s website. The FCC has links to some of these sites here: If you know the FCC identification (ID) number for a phone model (which can often be found somewhere on the phone or in the user manual), you can also go to the following web address: On this page, you will see instructions for entering the FCC ID number.”

After reviewing and dismissing the growing body of scientific evidence which finds that long-term cell phone phone use is associated with increased brain cancer risk, the ACS makes the following recommendation:

"With these limitations in mind, it is important that the possible risk of cell phone exposure continue to be researched using strong study methods, especially with regard to use by children and longer-term use."

Since virtually everyone in the U.S. uses a cell phone and all are exposed to cell phone radiation, one might wonder what the ACS has done to ensure that there is adequate funding for strong research on the cancer risk. Has the ACS devoted any research funding to the study of this environmental risk? Has the ACS used its influence to ensure that Federal agencies prioritize health and safety research regarding this risk?

Wi-Fi in Schools

Many experts have raised serious health concerns about exposing students to wireless radiation in school because no research proves that long-term exposure to low intensity, microwave radiation is safe for children. Moreover, a considerable amount of research published in peer-reviewed journals strongly suggests that wireless radiation from laptops and other wireless devices (including cell phones and cordless phones) is harmful to children's health.

Opposition to Wi-Fi adoption in schools is mounting as schools in the U.S. and other countries have begun to adopt Wi-Fi to provide internet access to students even though a wired solution would be safer. 

The Los Angeles Unified School District was the first major school district in the U.S. to adopt Wi-Fi in all classrooms. Following is a summary of the evidence that health experts submitted to the Los Angeles School Board in opposition to this plan. This is followed by a list of resources for those who are concerned about Wi-Fi adoption in their local schools.

Also see below an open letter from the BioInitiative Working Group to the CEO's of major technology corporations in the U.S.

For a  list of research studies that have found adverse biological or health effects from Wi-Fi radiation, see a website maintained by some scientists in the United Kingdom.

iPad Scandal in 2nd Largest School District in U.S.

The Superintendent of the Los Angeles Unified School District announced his resignation today due to a controversy over the district's billion-dollar iPad program. The program was suspended after the Superintendent received criticism about his close ties to Apple and Pearson, the company that manages the educational content.

Los Angeles Unified School District Accommodates Teacher Who Fell Ill After Wireless Installation

Students were bleeding from the ears and nose and no incident reports were allowed by the school states the teacher who required medical intervention.

The National Association for Children and Safe Technology, Oct 10, 2014

YouTube video: (3 minutes)
PRLog - Oct. 10, 2014 - In the Fall of 2014, LAUSD, the second largest public school district in the US, officially accommodated teacher Ms. Anura Lawson by approving her request to have the Wi-Fi turned off in her classroom during the 2014-2015 school year and alternatively approving a reassignment to a different school site where Wi-Fi has yet to be installed.

The Middle School teacher reported that she fell seriously ill after a wireless system upgrade in her school in Spring 2014.  She described her cardiac symptoms during a May 28, LAUSD Common Core Tech Project meeting. Ms. Lawson also stated, “The students are having nosebleeds and the main offices are refusing to do incident reports.  I have had two seventh grade students bleeding out of their ears.” See

This is the first accommodation in a US public school system for microwave sickness.

Microwave sickness, also known as electro hypersensitivity (EHS), is not widely recognized in the US.  However, physicians in many other countries are familiar with this medical condition and the diagnosis is more common.  EHS symptoms include:  headaches, dizziness, anxiety, rapid heart beat (tachycardia) and irregular heart beat (arrhythmia), ear and nose bleeds, tinnitus, red and irritated eyes, increased mucous and upper airway congestion, itchy skin rashes, abdominal pain, poor focus and attention, memory and sleep problems.

In March 2012, the Austrian Medical Association recognized and developed EHS treatment guidelines.  In the United States, adverse effects were identified before 1988 when a US Air Force Review stated that "Experimental evidence has shown that exposure to low intensity radiation can have a profound effect on biological processes."

The LAUSD Board of Education went ahead with a wireless technology plan in February 2013, even after they were presented with numerous letters from many noted medical doctors and researchers, including the American Academy of Environmental Medicine, imploring them to use wired technology in the classroom because of the health impacts from wireless radiation.  See

Wireless LAUSD classrooms typically employ 30+ devices (iPads) in addition to an industrial-sized router. These devices all emit microwave radiation and represent an unprecedented level of exposure to children.

Decades of accumulated research show wireless radiation damages neurological, immune, and reproductive systems in addition to increasing cancer risk.  Professor Olle Johansson, Karolinksa Institute, Stockholm Sweeden, has stated that wireless radiation exposure studies have indicated “irreversible sterility within five generations.”  As this damage is cumulative, the longer the radiation exposure, the greater the health impact over time.

"We are getting reports of headaches and cardiac issues from across the country.  The time to act is now," stated a spokesperson for the National Association for Children and Safe Technology (NACST).

NACST is an organization dedicated to raising awareness of the health impacts of wireless radiation on children.  They are calling for schools to use wired Internet only.  Their website details both the accumulated research showing wireless radiation’s acute as well as long term health impacts.

February 9, 2013

The Los Angeles Unified School District plans to spend $500 million to install Wi-Fi in every classrooom and provide every student with a wireless tablet or laptop.

The initial $50 million pilot phase for this project was discussed at a School Board meeting on February 13, 2013.  Although written and oral testimony was presented to the Board in opposition to this plan based on concerns about the health and safety of students and employees from continued exposure to Wi-Fi radiation, the Board approved the pilot plan.

For background on this issue and video clips, see these news stories:

Following are excerpts from eight of the letters submitted in opposition to the plan.

Excerpts from Selected Letters

Martin Blank, Ph.D., College of Physicians and Surgeons, Columbia University
“As a researcher on biological effects of electromagnetic fields (EMF) for over twenty five years, as well as one of the contributors to the 2007 and 2012 Bioinitiative Reports, I am writing to  you concerning the health risks associated with the radiation from WiFi and to urge you not to install WiFi in the schools in your district.”

“RF radiation can cause single and double strand DNA breaks at exposure levels that are currently considered safe under the FCC guidelines. There are also epidemiological studies that show an increased risk of cancers associated with exposure to RF.”

“RF has been shown to cause other potentially harmful biological effects, such as leakage of the blood brain barrier that can lead to damage of neurons in the brain, increased micronuclei (DNA fragments) in human blood lymphocytes--all at RF exposures that are well below the limits in the current FCC guidelines.“

“As noted above, many potentially harmful effects, such as the stress response and DNA strand breaks, occur at nonthermal levels. Since these field strengths do not cause a temperature increase (the only parameter currently accepted as dangerous), they are unwisely considered safe.  It is clear that the safety standards must be revised downward to take into account nonthermal as well as thermal biological responses. Given the problems in current standards, it is essential, for the protection of ourselves and our children, to take a precautionary approach and not install a WiFi system.”

Devra Davis, Ph.D., MPH, Environmental Health Trust
“In our new paper, we conclude that the weight of scientific evidence available at this time supports a classification of cell phone and other wireless technology as a "probable human carcinogen." (2A) The information on which we base this view includes experimental studies as well as a growing number of studies in humans. The criteria on which we rely have been validated through more than three decades of use by the IARC; other materials classified as probable human carcinogen include: diesel engine exhaust, tars, petroleum refining and a number of pesticides. Our paper reviews new studies not available to the IARC in its determination in 2011, including several reports from the team of Swedish investigators led by Lennart Hardell.” 

“We note that the American Academy of Pediatrics has expressed its concerns about the growing exposures to children in a letter to Congress dated 12 December 2012: ‘Children are disproportionately affected by environmental exposures, including cell phone radiation. The differences in bone density and the amount of fluid in a child’s brain compared to an adult’s brain could allow children to absorb greater quantities of RF energy deeper into their brains than adults. It is essential that any new standards for cell phones or other wireless devices be based on protecting the youngest and most vulnerable populations to ensure they are safeguarded through their lifetimes.'”

"As many researchers have noted, children are not merely little adults. Their brains and skulls absorb more radiation than do adults. Empirical data have shown a difference in the dielectric properties of tissues as a function of age, mostly due to the higher water content in children's tissues. High resolution computerized models based on human imaging data suggest that children are indeed more susceptible to the effects of EMF exposure at microwave frequencies."

"Please be aware that national authorities in France and Israel are advising against wi-fi expansion, especially in schools with younger children. Many authorities have noted that standards for wireless exposures differ by several orders of magnitude, with those in the home country of the World Health Organization, Switzerland being among the most stringent in the world."

"In fact, research on this topic remains poorly funded in the U.S. The absence of definitive information on risks from wi-fi in the U.S. at this time should not be interpreted as proof of safety."

"Wired systems are far more safe, secure, and speedy, and avoid potential long term public health issues. In addition, wired systems will protect the growing number of persons who are hypersensitive to wi-fi exposures, as well as limit risks to persons with pace-makers or those with other implanted electronic or metal devices that can absorb greater amounts of such radiation."

Katharina Gustavs, Cert. EOH, Building Biology Consultant IBN
 “Second, as an EMF consultant, I recommend choosing wired technologies, especially for Internet access in schools and, in general, keeping RF radiation exposures from all sources as low as possible. In this I follow the recommendations of the German Federal Office for Radiation Protection (2007), the Parliament of the Federal State of Salzburg (2007), the Israeli Parliament (2010), the International Commission for Electromagnetic Safety (ICEMS), the BioInitiative Working Group (2012), and the Seletun Scientific Panel (2010), just to name a few. Understand that with each additional wireless transmitter you add to the school environment, you unnecessarily increase the overall exposure to radio-frequency radiation for each student and staff member. Be inspired by other government agencies and school districts that try reducing the RF exposure of their students and staff members. “

“Last year the Physicians’ Working Group of the Competence Initiative not only launched another International Doctors’ Appeal, but they also released another warning regarding Wi-Fi in which it says: ‘Wi-Fi radiation seems to be perceived as particularly stressful. Not only electrohypersensitive people say so, but also healthy people report their discomfort in the presence of Wi-Fi radiation.”

“Laboratory tests of laptops have shown that the exposure level for a user can easily be greater than 100,000 μW/m2 when the laptop is placed in the lap, which is definitely higher than even elevated urban RF levels. The recently released EMF Guidelines by the EMF Working Group of the Austrian Medical Association consider any level greater than 1000
μW/m2 ‘very far above normal,’ and greater than 10 μW/m2 ‘far above normal.’”

“Do not be fooled by the URS report.* In my testing experience, people tend to adversely react to Wi-Fi radiation, starting at 100 μW/m2 (0.01 μW/cm2). And this is not a whole- body, time-averaged value, which would be much lower, but a peak value. The human body does not care about the ‘accepted practice’ of the FCC.”

“Also, basic logic seems to escape the authors of the URS report. On the one hand, they claim that ‘a cautionary level of 0.1 μW/cm2 is attainablewithin LAUSD classrooms.’ At what distance from any device? At the user distance? From one single Wi-Fi device? For any scenario when all devices in a given classroom are working? How can recommendation
number 3 on page 1-2 be reconciled with number 6? Does this mean that the recommended cautionary level only applies to a single frequency band, i.e. Wi-Fi? What about cumulative exposure from all the different types of wireless frequencies?”

“Ambient exposure levels in a classroom with a Wi-Fi access point may range from 100-4,000 μW/m2 (up to 90,000 μW/m2), depending on a person’s distance to the access point. Compared to the 10 million μW/m2 of the FCC limit, 1000 μW/m2 (0.1 μW/cm2) may sound rather small. Considering that the natural background radiation (in which
human life has evolved) is over a billion times lower (ca. 0.000001 μW/m2), this may give you pause. For your orientation, I have compiled a table with various Wi-Fi exposure levels: 

“The electromagnetic quality of our indoor environment is part of a healthy learning environment. Just because we cannot smell RF radiation does not mean it cannot cause any harm at low levels. Be smart; invest in wired networks and the future health of our children.”

Magda Havas, Ph.D., Environmental & Resource Studies, Trent University, Canada
“The safest way to connect to the internet in the classroom is through either Ethernet cable or through fiber optics.  The worst way to connect to the internet from a health perspective is through Wi-Fi routers.  However, if Wi-Fi routers are deployed in the classroom it is essential that the routers be turned off when not in use and/or turned down to minimize exposure of students and staff.”

“The scientific evidence clearly shows that microwave radiation at levels well below the Federal Communication Commission (FCC) guidelines and at levels now commonly found inside classrooms with Wi-Fi routers causes cancer in laboratory animals, causes heart palpitations in sensitive adults, causes reduced sperm motility and viability, and is associated with symptoms of electrosensitivity that include–but are not limited to–cognitive dysfunction, pain, fatigue, mood disorders (depression, anxiety, irritability), dizziness, nausea, weakness, skin problems, and tinnitus.”

“The current guidelines for microwave radiation are based on a heating effect of a healthy adult male (as they were originally designed for military personnel working near radar antennas).  These guidelines were never designed nor intended to protect children and pregnant women.  The guideline in the U.S. is calculated as the average exposure over a 30-minute period that does not raise the body temperature of tissue by 1 degree Celsius.  The U.S. has no long-term guidelines and no biological guidelines for microwave radiation.  The guidelines in Russia, Switzerland and many other countries are 100 times more protective than those in the United States.”

“Furthermore, in 2011 the World Health Organization classified radio frequency electromagnetic fields as a possible human carcinogen, which is a warning to governments around the world.   Why would we want to place a possible human carcinogen in the classroom?”

Martha Herbert, M.D., Harvard Medical School, Massachusetts General Hospital :
“In fact, there are thousands of papers that have accumulated over decades and are now accumulating at an accelerating pace, as our ability to measure impacts become more sensitive that document adverse health and neurological impacts of EMF/RFR.  Children are more vulnerable than adults, and children with chronic illnesses and/or neurodevelopmental disabilities are even more vulnerable. “

“EMF/RFR from wifi and cell towers can exert a disorganizing effect on the ability to learn and remember,  and can also be destabilizing to immune and metabolic function.  This will make it harder for some children to learn, particularly those who are already having problems in the first place.“

“I urge you to step back from your intention to go wifi in the LAUSD, and instead opt for wired technologies, particularly for those subpopulations that are most sensitive.  It will be easier for you to make a healthier decision now than to undo a misguided decision later.”

Olle Johansson, Ph.D., Dept of Neuroscience, Karolinska Institute, Sweden
 “In November, 2009, a Scientific Panel comprised of international experts on the biological effects of electromagnetic fields met in Seletun, Norway, for three days of intensive discussion on existing scientific evidence and public health implications of the unprecedented global exposures to artificial electromagnetic fields (EMF) from telecommunications and electric power technologies. This meeting was a direct consequence of on-going discussions already from the mid-nineties, when cellular communications infrastructure began to rapidly proliferate, and stretching through, among many, the Benevento (2006), Venice (2008) and London (2009) Resolutions from this decade, and involving important conclusions drawn from the 600-page Bioinitiative Report published August 31, 2007, which was a review of over 2,000 studies showing biological effects from electromagnetic radiation at non-thermal levels of exposure, which partly was published subsequently in the journal Pathophysiology (Volume 16, 2009). The Bioinitiative Report has, in addition, recently been updated (2012).”

“The Seletun Scientific Statement (2011) recommends that lower limits be established for electromagnetic fields and wireless exposures, based on scientific studies reporting health impacts at much lower exposure levels. Many researchers now believe the existing safety limits are inadequate to protect public health because they do not consider prolonged exposure to lower emission levels that are now widespread.”

“Furthermore, based on the available scientific data, the Seletun Scientific Panel states that:

· Sensitive populations (for example, the elderly, the ill, the genetically and/or immunologically challenged) and children and fetuses may be additionally vulnerable to health risks; their exposures are largely involuntary and they are less protected by existing public safety standards.

· It is well established that children are more vulnerable to health risks from environmental toxins in general.

· The Panel strongly recommends against the exposure from wireless systems of children of any age.

· The Panel strongly recommends against the exposure from wireless systems of pregnant women.”

“Another misunderstanding is the use of scientific publications (as the tobacco industry did for many years) as 'weights' to balance each other. But you can NEVER balance a report showing a negative health effect with one showing nothing! This is a misunderstanding which, unfortunately, is very often used both by the industrial representatives as well as official authorities.”

Joel Moskowitz, Ph.D., School of Public Health, University of California, Berkeley
 “Based upon my review of the research of the health effects associated with exposure to radiofrequency (RF) electromagnetic radiation (EMR), especially microwave radiation, I feel compelled to register my concern that adoption of Wi-Fi in LAUSD classrooms is likely to put at risk the health of many students and employees in the District.”

“…I was concerned about the health risks of unnecessarily subjecting 660,000 children to 13,000 hours of Wi-Fi microwave radiation during their K-12 school years.”

“I have been calling on the FCC to strengthen its standards and testing procedures to protect the public and workers from the low-intensity, non-thermal risks of RF EMR exposure that have been reported in hundreds, if not thousands, of research studies. These include increased risk of neurological and cardiovascular problems, sperm damage and male infertility, reproductive health risks, and cancer.”

“The precautionary principle should be applied to this critical policy decision. This principle, developed at a U.N. environmental conference in 1992 states that in the absence of scientific consensus if an action has a suspected risk of causing harm, the burden of proof it is not harmful falls on those taking the action, and all reasonable measures to reduce the risk must be taken. Internet access can be provided to students through wires or optical fiber without installing Wi-Fi in the classrooms.”

“The LAUSD will place hundreds of thousands of school children at risk for illness, learning impairments and other health problems by choosing a delivery technology that produces a toxic emission (radiofrequency and microwave radiation) that has recently been classified as a Possible Human Carcinogen.”

“There is overwhelming evidence that children are more vulnerable than adults to many different exposures (Sly and Carpenter, 2012), including RFR (Wiart et al, 2008), and that the diseases of greatest concern are cancer and adverse effects on neurodevelopment. “

“Existing FCC safety standards are under formal review by the FCC (Proceeding 03-137).  The US Government Accountability Office Report of 2012 recommends to the FCC that it formally reassess, and, if appropriate, change it's current RF energy exposure limit and mobile phone testing requirements related to likely usage configurations,  particularly when phones are held against the body (US GAO, 2012).  The existing FCC public safety standards cannot be presumed for purposes of the LAUSD decision on wireless to be protective of public health under these circumstances.  The existing safety limits do not protect against chronic exposures nor against non-thermal effects of radiofrequency and microwave radiation on human health.  They are specifically not protective of children or smaller-stature individuals (they are developed to be suitable to protect a six-foot man (in stature). They address acute, but not chronic exposures.  And they are not protective against biological effects of non-thermal low-intensity RFR exposures for either children,  adults, or the disabled.”

“LAUSD must incorporate appropriate measures to address the recent World Health Organization International Agency for Research on Cancer (IARC) classification of RFR as a Possible Human Carcinogen before subjecting widespread hundreds of thousands of its District personnel and students to a preventable toxic exposure. The WHO IARC  classified RF radiation as a Group 2B Possible Human Carcinogen; it joins the IARC classification of ELF-EMF (Extremely Low Frequency Electromagnetic Fields) as a Group 2B Possible Human Carcinogen.  The evidence for carcinogenicity for RFR was primarily from cell phone/brain tumor studies but IARC applies this classification to all RFR exposures.”

“New scientific studies of radiofrequency radiation of the kind and at the levels associated with wireless classroom environments report that chronic, whole-body RFR exposure at levels as low as 0.003 microwatts per square centimeter result in adverse health effects on children and adolescents (Thomas et al 2008; Heinrich et al 2010; Thomas et al 2010; Mohler et al 2010). Wireless classrooms will create unavoidable and involuntary exposure to RFR at levels shown to adversely affect memory, learning, cognition, attention, concentration and behavior to school occupants. No level of RFR exposure has been conclusively determined to be safe.”

“LAUSD should not encourage or mandate the use of wireless devices like iPads or wireless computers with associated wireless access points installed in classrooms; or cell phones in learning environments on LAUSD properties. There is evidence that is sufficient to warn against chronic use of wireless devices near or worn on the body related to reproductive organs in both males and females (See Footnote 1).”

March 11, 2013

Dear School Board Members:

I wish to bring to your attention a press release I distributed today as it is relevant to the District's Technology Plan. At a recent meeting, the Board decided to adopt a Wi-Fi system in the LA Unified schools against the recommendations of some American health experts as well as the Council of Europe: and

As you may know, the FCC's regulatory standard protects the population from thermal exposure to microwave radiation from wireless equipment but not from low-intensity, non-thermal exposures.

Since the District ignored these warnings and intends to install wireless networks in the schools, I suggest you consider a requirement that the systems be designed consistent with the ALARA (as low as reasonably achievable) principle in order to minimize potential health risks to students and staff. It would be prudent for the Board to follow this course of action based upon the precautionary principle.

In 2003, a major telecommunications company acknowledged in a patent filing that exposure to low intensity, non-thermal wireless radiation is carcinogenic. The technology described in this patent could substantially reduce microwave radiation exposure from a local wireless network. Although I have not done a patent search, I would imagine that the wireless industry holds numerous patents that could reduce microwave radiation exposure from wireless local networks. Unfortunately, the industry has little incentive to apply these patents to extant technology because the FCC has been lax in its regulation of microwave radiation.

The District could become a model for the nation by adopting a Wi-Fi system and distributing tablets/laptops that are compliant with the ALARA principle. School districts and their students throughout the country could also benefit if the Board requires the wireless industry to make this  option available to the public.

Wireless Industry's Patented System to Reduce Cancer Risk from Wireless Local Networks Never Adopted 

A major telecom company patented a system to reduce "electrosmog" from wireless local networks to reduce cancer risks associated with non-thermal exposures to microwave radiation. The industry has known the risks for many years but has failed to act. Joel M. Moskowitz, PRLog (Press Release) - Mar 11, 2013

Swisscom AG, a major telecommunications provider in Switzerland, filed U.S. and international patent applications for an innovative system to reduce “electrosmog” from wireless local networks (i.e., Wi-Fi) in 2003.

This patent application acknowledged the cancer risk from exposure to wireless radiation eight years before the WHO’s International Agency for Research on Cancer declared that radiofrequency energy, including cell phone and Wi-Fi radiation, is a “possible carcinogen” to humans, like DDT and lead.

Furthermore, the application acknowledged that low-intensity, non-thermal exposures to wireless radiation is genotoxic. This is critical because the current U.S. regulatory standard for wireless radiation, established in 1996, does not protect us from non-thermal exposures ...

On March 19, the Executive Committee of the American Academy of Environmental Medicine, an international association of physicians and other professionals, wrote a letter to the Los Angeles Unified School District that makes the following recommendation:
"do not add to the burden of public health by installing blanket wireless internet connections in Los Angeles schools. Hardwired internet connections are not only safer, they are stronger, and more secure."
The letter discusses why precaution is warranted:
"There is consistent emerging science that shows people, especially children are affected by the increasing exposure to wireless radiation. In September 2010, theJournal of the American Society for Reproductive Medicine ‐ Fertility and Sterility reported that only four hours of exposure to a standard laptop using WiFi caused DNA damage to human sperm."
"In May 2011, the World Health Organization elevated exposure to wireless radiation, including WiFi, onto the Class 2b list of Carcinogens."
"In October 2012, the AAEM issued a public warning about WiFi in schools that
'Adverse health effects from wireless radio frequency fields, such as learning disabilities, altered immune responses, and headaches, clearly exist and are well documented in the scientific literature. Safer technology, such as use of hardwiring, is strongly recommended in schools.'”
"In December 2012, the American Academy of Pediatrics ‐ representing 60,000 pediatricians, wrote to Congress requesting it update the safety levels ofmicrowave radiation exposure especially for children and pregnant women."
"The WiFi systems in schools are typically hundreds of times more powerful than the home consumer systems you may be familiar with. They are also dozens of times more powerful than the cafe and restaurant systems you may have beenexposed to. The WiFi systems in schools are necessarily more powerful than anymicrowave communication systems in any other setting because they are requiredto run hundreds of computers simultaneously. They are also exposing children ‐ the most vulnerable to microwave radiation ‐ to extended periods all day, for their entire childhood."
"This is an unprecedented exposure with unknown outcome on the health and reproductive potential of a generation."
"To install this system in Los Angeles risks a widespread public health question that the medical system is not yet prepared to answer."
The Academy forewarns the District, "caution must be exercised to prevent a potential public health disaster."
"It is unlikely that there are currently enough doctors in Los Angeles County familiar with the biological effects of microwave radiation to diagnose and treat the numbers of children who will potentially become symptomatic from exposure to your wireless system should you elect to install it. Statistics show that you can expect an immediate reaction in 3% of your students and time‐delayed reactions in 30% of them. This will also include teachers."

CEO Wireless Letter from the Bioinitiative Working Group

September 17, 2014

[The BioInitiative Working Group consists of 29 scientists from ten nations.]

On behalf of the BioInitative Working Group, we are writing to express our concern about the views expressed by CEOs from Google, Dell, Apple, Adobe, eBay, Facebook, the George Lucas Educational Foundation and others to the FCC supporting wireless technologies in schools ....

Saturating schools with wireless technology will likely create unnecessary liability for municipalities and result in a loss of public trust and confidence in the corporations that push their wireless products with a blind eye toward health concerns.

Epidemiological studies show links between radiofrequency radiation (RFR) exposure and cancers, neurological disorders, hormonal changes, symptoms of electrical hypersensitivity (EHS) and more. Laboratory studies show that RFR exposure increases risk of cancer, abnormal sperm, learning and memory deficits, and heart irregularities. Fetal exposures in both animal and human studies result in altered brain development in the young offspring, with disruption in learning, memory and behavior. 

The brain development of a fetus can be impaired by in-utero exposure to a pregnant woman. The evidence for these statements is based on hundreds of published, peer-reviewed scientific studies that report adverse effects at levels much lower than current FCC public safety limits. WiFi is schools, in contrast to wired internet connections, will increase risk of neurologic impairment and long-term risk of cancer in students. Corporations cannot avoid responsibility simply by asserting compliance with existing legal, but outdated and inadequate FCC public safety limits ...

Many schools and educational institutions are using wireless Wi-Fi and Tablet technologies in their education. Recently WHO IARC classified radiofrequency (RF) radiation  ‘possibly carcinogenic to humans’. Currently guidance levels for electromagnetic fields (including RF) are based on thermal effects while effects have been reported on non-thermal levels. Possibly these biological, non-thermal effects are brain-related and affect cognition, memorizing and  learning. We start by describing our measurement method used for Wi-Fi routers and laptop Wi-Fi antennas. Then a historical overview on thermal and non-thermal viewpoints is provided. The objective of this study is to quantify the actual RF radiation levels around Wi-Fi access points and laptop computers at educational facilities and to assess their compliance with the current thermal-only guidelines and also with precautionary, biological guidance levels. This paper ends to recommendations how to minimize radiation exposure in educational institutions.
