"Wireless Radiation and Public Health: What the WHO Reviews Reveal and Don't"
ICBE-EMF Press Conference Oct 7, 2025, YouTube video (1:06:09)
The
WHO is investigating the health effects of cell tower and cell phone
wireless radiofrequency (RF) radiation. The International Commission on
the Biological Effects of Electromagnetic Fields (ICBE-EMF) held a press
conference to announce the publication of its latest peer-reviewed
paper in the journal Environmental Health entitled, “The
WHO-Commissioned Systematic Reviews on Health Effects of Radiofrequency
Radiation Provide No Assurance of Safety.”
Link to the open access paper https://ehjournal.
The
paper identifies serious methodological flaws in the World Health
Organization (WHO)-commissioned reviews that assessed the health impacts
of radiofrequency (RF) radiation from wireless technology including
cell phones, cell towers, Wi-Fi networks and 5G. ICBE-EMF concluded
based on its substantial, collective, multidisciplinary expertise in
this field, that the WHO-commissioned systematic reviews are simply
inadequate to conclude that wireless radiation is safe or that current
ICNIRP/FCC exposure limits are reliable.

International Commission
on the Biological Effects of Electromagnetic Fields Challenges WHO-Commissioned
Reviews on Wireless Radiofrequency Radiation Safety
The safety of wireless technology is not assured,
scientists state
BERKELEY, CA October 2,
2025 – The International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) today announced
the online publication of its latest paper, "The WHO-Commissioned Systematic Reviews on
Health Effects of Radiofrequency Radiation Provide No Assurance of
Safety," in the journal Environmental
Health. The paper critically examines the World Health Organization
(WHO)-commissioned systematic reviews on the health effects of radiofrequency
(RF) radiation, identifying significant flaws that undermine their conclusions
regarding safety.
RF radiation, a type of
non-ionizing electromagnetic field (EMF), is emitted by ubiquitous wireless
devices and telecommunications infrastructure, including cell phones, Wi-Fi
routers, cell towers, and building-mounted antennas. While acknowledging the
importance of the WHO's objective to evaluate the literature on RF radiation
and adverse health effects, the ICBE-EMF paper asserts that methodological weaknesses and potential biases compromise
the reliability of the published reviews.
Dr. John Frank, a physician and epidemiologist at the
University of Edinburgh, Professor Emeritus, University of Toronto, and
ICBE-EMF Chairperson, stated, "We at
ICBE-EMF find, based on our substantial, collective, multidisciplinary
expertise in this field, that the WHO-commissioned systematic reviews are
simply inadequate to conclude that wireless radiation is safe or that
ICNIRP/FCC limits are reliable. Presenting these flawed reviews as evidence of
safety for ICNIRP and the FCC's current exposure limits would mislead the
public.”
The ICBE-EMF will be holding a press conference on October 7, 2025,
at 9:00 AM Pacific to present their findings detailed
in the publication.
Concerns Over Bias and
Flawed Methodology
A central concern highlighted
in the ICBE-EMF paper is the extensive involvement of individuals affiliated
with the International Commission on Non-Ionizing Radiation Protection (ICNIRP)
in the production of these WHO-commissioned reviews. ICNIRP and the WHO’s EMF
Program share a common origin and have historically maintained that thermal
effects are the only established health risks of RF radiation exposure. Given
that ICNIRP's recommended RF radiation exposure limits have been adopted by
most countries for the past 30 years, the ICBE-EMF is raising questions
regarding potential bias in these reviews and the adequacy of current exposure
limits for protecting public health.
Dr. Ron Melnick, past Chair
of the ICBE-EMF, now Senior Advisor and former senior toxicologist at the
National Toxicology Program and the National Institute of Environmental Health
Sciences (NIEHS), elaborated on their findings. "We began reviewing the
WHO-commissioned assessments because of our longstanding involvement in this
research and the potential influence these reviews could have on future policy
decisions," said Dr. Melnick. "We uncovered numerous flaws, including
the exclusion of relevant studies, reliance on weak studies, inappropriate
combining of studies with vastly different exposure conditions, and undisclosed
biases among the authors."
Evidence of Harm and Need
for Stronger Protections
The ICBE-EMF paper
specifically notes that the WHO-commissioned systematic reviews on cancer and
reproductive effects in experimental animals indicated a high certainty of
association between RF radiation exposure and increased incidences of heart
schwannomas and reduced male fertility. Furthermore, these reviews provided
quantitative data that, according to the ICBE-EMF, could and should be used to reduce
exposure limits and improve protection for humans.
Dr. Joel Moskowitz, Director
of the Center for Family and Community Health at the University of California,
Berkeley, further emphasized the analytical weaknesses. "Eleven of the
twelve WHO-sponsored systematic reviews relied upon multiple quantitative
analyses (meta-analyses) of primary studies on RF radiation health effects. In
most instances, we found that these analyses had serious methodological
weaknesses that undermined interpretation of the results and invalidated the
authors’ conclusions, which were based upon these results," stated Dr.
Moskowitz.
The ICBE-EMF has previously published work
demonstrating how scientific evidence over the past three decades invalidates
many assumptions underlying ICNIRP's RF radiation exposure limits. With
mounting scientific evidence and widespread, increasing population exposure to
RF radiation, the ICBE-EMF stresses the urgent need to reduce exposures and
strengthen safety limits, particularly for vulnerable populations such as
pregnant individuals, children, and those with chronic health conditions,
including electromagnetic hypersensitivity.
The ICBE-EMF concludes that
the WHO-commissioned systematic reviews do not provide proof of safety for cell
phones or other wireless communication devices, nor do they justify the RF
radiation exposure limits currently specified in ICNIRP’s guidelines. The
organization calls for urgently needed, science-based public health guidelines
that are genuinely protective of human health and the environment.

Abstract
The World Health Organization (WHO) commissioned 12 systematic reviews
(SR) and meta-analyses (MA) on health effects of exposure to
radiofrequency electromagnetic fields (RF-EMF). The health outcomes
selected for those reviews (cancer, electromagnetic hypersensitivity,
cognitive impairment, birth outcomes, male fertility, oxidative stress,
and heat-related effects) were based on a WHO-conducted international
survey. The SR of the studies of cancer in laboratory animal studies was
the only one that did not include a MA, because those authors
considered it inappropriate due to methodological differences among the
available studies, including differences in exposure characteristics
(carrier frequency, modulation, polarization), experimental parameters
(hours/day of exposure, duration of exposure, exposure systems), and
different biological models. MAs in all the other SRs suffered from
relatively few primary studies available for each MA (sometimes due to
excessive subgrouping), exclusion of relevant studies, weaknesses in
many of the included primary studies, lack of a framework for analyzing
complex processes such as those involved in cognitive functions, and/or
high between-study heterogeneity. Due to serious methodological flaws
and weaknesses in the conduct of the reviews and MAs on health effects
of RF-EMF exposure, the WHO-commissioned SRs cannot be used as proof of
safety of cell phones and other wireless communication devices. However,
the animal cancer SR, which was rated as “high certainty of evidence”
for heart schwannomas and “moderate certainty of evidence” for brain
gliomas, provided quantitative information that could be used to set
exposure limits based on reducing cancer risk. The multiple and
significant dose-related adverse effects found in the SRs on male
fertility and pregnancy and birth outcome should also serve as the basis
for policy decisions to lower exposure limits and reduce human
reproductive risks. The report of harmful effects (e.g., cancer,
reproductive toxicity, etc.) at doses below the adverse health effect
threshold claimed by ICNIRP demonstrates that current exposure limits to
RF-EMF, which were established by applying arbitrary uncertainty
factors to their putative adverse threshold dose, lack scientific
credibility.

New WHO-Funded Study Reports High Certainty of the Evidence Linking Cell Phone Radiation to Cancer in Animals
Scientific Experts Urge the FCC to Establish Science-Based Exposure Limits to Address Wireless Health Risks
Media Contact: communications@icbe-emf.org
Press Release April 27, 2025
Environment International has published a new systematic review,
partially funded by the World Health Organization, concluding that
there is high certainty of the evidence linking cell phone
radiofrequency (RF) radiation to two types of cancer in animals. In
response, leading scientists from the International Commission on the Biological Effects of Electromagnetic Fields
(ICBE-EMF) are calling for immediate policy action to protect public
health and the environment, warning that further delay could have
serious consequences amid the global surge in the use of wireless
communication devices.
What the Review Found
A new systematic review of 52 animal
studies, “Effects of Radiofrequency Electromagnetic Field Exposure on
Cancer in Laboratory Animal Studies” by Mevissen et al. (2025),
concluded there is high certainty of the evidence linking RF radiation
exposure to two types of tumors: gliomas in the brain and malignant
schwannomas in the heart. Notably, the same types of tumors have also
been observed in human studies, adding significant confidence that the
associations observed in human studies are real.
The review also found moderate
certainty of evidence of an increased risk of rare tumors, such as
pheochromocytomas in the adrenal glands and hepatoblastomas in the
liver. Additionally, some studies indicated a possible association with
lymphomas, although the findings were inconsistent.
ICBE-EMF highlights that in 2011, the
World Health Organization’s International Agency for Research on Cancer
(IARC) classified radiofrequency radiation (RF-EMF) as a Group 2B
“possible” human carcinogen, noting limited animal evidence. Since then,
major animal studies — including those by the U.S. National Toxicology
Program and the Ramazzini Institute — have found that RF radiation
exposure causes cancer in rats.
The new WHO-funded review, concluding
there is “high certainty” animal evidence of cancer causation,
reinforces calls for IARC to urgently reevaluate the cancer
classification of RF radiation.
Given this high level of certainty,
government policymakers worldwide should immediately move to revise
their RF radiation exposure limits to protect public health and the
environment.
Statements by Experts of the International Commission on the Biological Effects of Electromagnetic Fields
“The evidence is now clear —cell
phone radiation can cause cancer in animals in concordance with the
tumor types identified in human studies of mobile phone users. As animal
studies are essential for predicting cancer risk in humans, governments
should develop science-based safety standards to protect human health.
The conclusion of the study commissioned by the WHO shows that the
long-standing assumption current government limits are based on — that
cell phone RF radiation can only cause harm through tissue heating — is
wrong” stated Ron Melnick, PhD, Chair of the ICBE-EMF and former senior
toxicologist and Director of Special Programs at the National Toxicology
Program and the National Institute of Environmental Health Sciences
(NIEHS).
“The preponderance of the research
published since 1996 finds adverse biologic and health effects from
long-term exposure to low levels of modulated or pulsed wireless RF
radiation. Given the widespread global usage of wireless among users of
all ages, even a very small increase in the incidence of disease will
have broad implications for public health,” stated Joel Moskowitz,
PhD, Director of the Center for Family and Community Health at the
School of Public Health, University of California, Berkeley, also an
ICBE-EMF member.
“To protect public health and the
environment, exposure to cell phone and wireless radiation must be
significantly reduced,” said Elizabeth Kelley, Managing Director of
ICBE-EMF. She referenced the EMF Scientist Appeal now
signed by 267 scientists from 45 nations. “Hundreds of scientists
worldwide agree that current exposure limits are outdated and do not
adequately protect against health risks.”
ICBE-EMF emphasizes that governments
must act immediately to strengthen regulatory limits on wireless
radiation to protect public health. Wildlife exposures must be
mitigated. Current exposure standards, based on outdated assumptions, do
not reflect the scientific evidence linking RF radiation to cancer and
other health effects.
ICBE-EMF also highlights practical steps
the public can take to reduce exposure — such as using speakerphone or
wired headsets, keeping devices away from the body, and limiting
wireless use among children — but stresses that personal actions are not
a substitute for government-enforced safety standards. Stronger,
science-based regulations are urgently needed to address the widespread
and increasing exposure to wireless radiation.

ICBE-EMF finds serious problems with WHO-Commissioned review of human observational studies on the effects of exposure to radio-frequency EMFsTUCSON, AZ – July 15, 2024 – The International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) documented serious problems with a WHO-commissioned review of research on the effects of exposure to radio-frequency electromagnetic fields (RF-EMF) in a commentary published today in the journal Reviews on Environmental Health.Our commentary, “A critical appraisal of the WHO 2024 systematic review of the effects of RF-EMF exposure on tinnitus, migraine/headache, and non-specific symptoms,” discusses major problems with a recent review of human observational studies on this topic by Röösli and colleagues (2024) that was published in the journal Environment International.We call for a retraction of this paper. Contrary to the opinion of the authors, we conclude that the body of evidence reviewed for this paper is not adequate to either support or refute the safety of current exposure limits – largely due to the very small number and low methodological quality of the relevant primary studies to date, and the fundamental inappropriateness of meta-analysis for the handful of very heterogeneous primary studies identified for each of the analyzed exposure/outcome combinations.Furthermore, the ICBE-EMF calls for an impartial international investigation, by unconflicted experts, of both the currently available evidence base on these issues, as well as related research priorities for the future.The ICBE-EMF is made up of a multidisciplinary consortium of scientists, doctors and related professionals who are involved with research related to the biological and health effects of electromagnetic frequencies up to and including 300 GHz.

New peer-reviewed letter presents scientific case for retraction of conclusionsof COSMOS brain tumor risk study.
TUCSON, AZ – June 26, 2024 – The International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) exposed major flaws with the COSMOS study of brain tumor risk from cell phone use in a letter to the editor published today in the journal Environment International, "COSMOS: A methodologically-flawed cohort study of the health effects from exposure to radiofrequency radiation from mobile phone use."
The letter discusses serious problems with a recent COSMOS paper that provided interim results about brain tumor risk from mobile phone use. The letter calls for a retraction of the paper's conclusions and demands that the data set be made available to independent investigators who have no industry ties. Excerpts from the letter appear below.
The response to our letter by the authors of the COSMOS paper failed to adequately address our concerns.
COSMOS (“Cohort Study on Mobile Phone Use and Health”) is a 20-30-year cohort study investigating the possible health effects of long-term use of mobile phones and other wireless technologies. The study enrolled over 290,000 mobile phone users from six European countries (Denmark, Finland, France, Sweden, the Netherlands, and the United Kingdom).
The ICBE-EMF is made up of a multidisciplinary consortium of scientists, doctors and related professionals who are involved with research related to the biological and health effects of electromagnetic frequencies up to and including 300 GHz. The organization makes recommendations that include and go beyond establishing numerical exposure guidelines based on the best peer-reviewed scientific research publications.

Simple engineering fixes could dramatically reduce cellphone radiation, scientists say
Industry will now have to start competing on safety
ICBE-EMF, Tucson, AZ, April 4, 2023 -- Six simple engineering fixes could dramatically reduce radiation emitted by cellphones according to a group of scientists. The fixes are easy to implement, and in one case the fix relies on technology already patented by the industry.
The International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) reported its findings today in an open access, peer-reviewed article, "Cell Phone Radiation Exposure Limits and Engineering Solutions," published in the International Journal of Environmental Research and Public Health.
“Given the growing evidence of the health effects of radiation from cellphones and cell towers, I believe the wireless industry is going to have to start competing on safety,” said Joel Moskowitz, one of the authors who is also director of the Center for Family and Community Health at the University of California, Berkeley.
“With the proliferation of online advice and consultants helping people reduce their exposures, the concern about the safety of cellphones and other wireless devices has moved into the mainstream,” Moskowitz added.
“We will undoubtedly hear from many in the industry that a move toward safer cellphones and other wireless devices will be too costly and unnecessary,” Moskowitz said. “But carmakers said the same thing when the public demanded safer cars and the government required them. Today, those same carmakers compete on safety.”
“This competition for safety can move forward without a change in the current government standards,” Moskowitz explained. “Ultimately, I believe governments around the world will be playing catch-up with industry and consumers.”
“The six engineering solutions outlined in this paper provide a significant move forward in cellphone safety,” said Elizabeth Kelley, one of the authors of the paper and managing director of the International Commission on the Biological Effects of Electromagnetic Fields. “The scientists and engineers proposing them stand ready to assist the cellphone industry with implementing them as soon as is practical.”
Kelley added, “Some of the proposed solutions are just common sense. Using Wi-Fi to make cellphone calls whenever feasible dramatically reduces radiation emissions from the phone.” And, when a cellphone is sitting on the nightstand while the user is sleeping, it doesn’t need to communicate constantly with a cell tower to relay its location. “Why not shut down these transmissions—which cause frequent radiation emissions—when our phones are stationary such as when they sitting on a bedside table as we sleep or on our desk next to us as we work?”
Kelley said, “These common-sense changes can quickly and dramatically reduce radiation exposure from cellphones. Implementing them will create a healthier environment for all of us while still allowing us to stay connected to others and to the information we need daily.”
The paper also examines the history behind the current cellphone emissions standards and finds a trail of dated assumptions and poorly designed experiments and tests that don’t reflect how people use cellphones today.
Paul Héroux, the first author of this paper and a professor in the School of Population and Global Health at McGill University in Montreal, said the team of scientists and engineers who worked on the paper “identified seven blind spots in the methods and experiments upon which our current cellphone radiation emission standards and guidelines are based. These blind spots call into serious question the validity of those standards."
In his written statement Héroux recommends that two things be done right away:
- Test cellphones “using test designs that represent actual use and that rely on the growing body of research demonstrating biological effects from radiation emitted by cellphones.”
- “Demand a quantitative health risk assessment of cellphone use and wireless infrastructure. This type of scientific assessment is routinely used by government agencies worldwide. In the United States the Environmental Protection Agency, the Food and Drug Administration, the Centers for Disease Control and Prevention, and the Occupational Safety and Health Administration all use quantitative health risk assessments to determine potential human health risks associated with exposure to hazardous agents or activities.”

Wireless Technology Not Adequately Assessed for Hazards to Human Health and Environment
TUCSON, AZ – October 18, 2022 – The International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) is challenging the safety of current wireless exposure limits to radiofrequency radiation (RFR) and is calling for an independent evaluation.
Published today in the journal Environmental Health, “Scientific evidence invalidates health assumptions underlying the FCC and ICNIRP exposure limit determinations for radiofrequency radiation: implications for 5G,” demonstrates how the U.S. Federal Communications Commission (FCC) and the International Commission on Nonionizing Radiation Protection (ICNIRP) have ignored or inappropriately dismissed hundreds of scientific studies documenting adverse health effects at exposures below the threshold dose claimed by these agencies, which was used to establish human exposure limits. The authors argue that the threshold, based on science from the 1980s – before cell phones were ubiquitous -- is wrong, and these exposure limits based on this threshold do not adequately protect workers, children, people with electromagnetic hypersensitivity, and the public from exposure to the nonionizing radiation from wireless data transmission.
“Many studies have demonstrated oxidative effects associated with exposure to low-intensity RFR, and significant adverse effects including cardiomyopathy, carcinogenicity, DNA damage, neurological disorders, increased permeability of the blood-brain barrier, and sperm damage,” explains Dr. Ronald Melnick, Commission chair and a former senior toxicologist with the U.S. National Toxicology Program at the National Institute of Environmental Health Sciences. “These effects need to be addressed in revised and health-protective exposure guidelines. Furthermore, the assumption that 5G millimeter waves are safe because of limited penetration into the body does not dismiss the need for health effects studies.”
Dr. Lennart Hardell, former professor at Örebro University Hospital in Sweden and author of more than 100 papers on non-ionizing radiation, added, “Multiple robust human studies of cell phone radiation have found increased risks for brain tumors, and these are supported by clear evidence of carcinogenicity of the same cell types found in animal studies.”
The Commission believes that an independent evaluation based on the scientific evidence with attention to the knowledge gained over the past 25 years is needed to establish lower exposure limits. The Commission is also calling for health studies to be completed prior to any future deployment of 5G networks.
Elizabeth Kelley, the Commission's managing director, noted that “ICBE-EMF was commissioned by the advisors to the International EMF Scientist Appeal, a petition signed by more than 240 scientists who have published over 2,000 papers on EMF, biology, and health, and that “The commissioners have endorsed the Appeal’s recommendations to protect public and environmental health.”
- ICBE-EMF scientists report that exposure limits for radiofrequency (or wireless) radiation set by ICNIRP and the FCC are based on invalid assumptions and outdated science, and are not protective of human health and wildlife.
- ICBE-EMF calls for an independent assessment of the effects and risks of radiofrequency radiation based on scientific evidence from peer-reviewed studies conducted over the past 25 years. The aim of such assessment would be to establish health protective exposure standards for workers and the public.
- The public should be informed of the health risks of wireless radiation and encouraged to take precautions to minimize exposures, especially for children, pregnant women and people who are electromagnetically hypersensitive.
- ICBE-EMF calls for an immediate moratorium on further rollout of 5G wireless technologies until safety is demonstrated and not simply assumed.
