US Government Reports on Cell Phones, Radiofrequency and Electromagnetic Fields


US Government Reports on Cell Phones2016: USA National Institutes of Environmental Health Sciences (NIEHS) National Toxicology Program (NTP) issued a Report on Partial Findings of the Studies on Radiofrequency Radiation.

These studies which took took over 15 years and 25 million dollars are the only US government funded studies on chronic exposure to wireless radiation. They exposed rats and mice to long term low level wireless frequencies. In 2016, the NTP findings were released which found adverse effects after long term exposure to cell phone radiation:

  • Increased incidences of glioma (a rare, aggressive and highly malignant brain cancer) as well as schwannoma (a rare tumor of the nerve sheath) of the heart were found in both sexes of rats, but reached statistical significance only in males.
  • Increased incidences of rare, proliferative changes in glial cells of the brain and in Schwann cells (nerve sheath) in the heart of both sexes of rats, while not a single unexposed control animal developed these precancerous changes.
  • DNA damage (comet assay) was induced with both modulations of radiofrequency radiation (RFR) in both rats and mice (mixed results in tissues and brain regions).
  • The cancers found in the rats are the same types of cancers found to be increased in human long term users of cell phones and therefore the NTP researchers state that these findings support evidence for the WHO IARC carcinogen classification of radiofrequency.

Results from this study clearly show that biological impacts occur at non-thermal exposures like those that take place from cell phones today. Data analyses in mice are ongoing. The complete results from these rodent studies will be available in NTP Technical Reports by the end of 2017.

2014: U.S. Department of the Interior Letter to the National Telecommunications and Information Administration Stating FCC Guidelines are Outdated.

Willie R. Taylor, Director, of the Department of Interior Office of Environmental Policy and Compliance writes that “a significant issue associated with communication towers involves impacts from non-ionizing electromagnetic radiation emitted by these structures” and details science that found “strong negative correlations between levels of tower-emitted microwave radiation and bird breeding, nesting, and roosting in the vicinity of electromagnetic fields including nest and site abandonment, plumage deterioration, locomotion problems, reduced survivorship, and death in House Sparrows, White Storks, Rock Doves, Magpies, Collared Doves, and other species”. The letter states that FCC RF exposure limits are out of date and irrelevant statin, “However, the electromagnetic radiation standards used by the Federal Communications Commission (FCC) continue to be based on thermal heating, a criterion now nearly 30 years out of date and inapplicable today”. Read the 2014 U.S. Department of the Interior Letter

2012: FCC opens Official Inquiry Into Human Exposure Guidelines:

In response to the GAO Report, the FCC opened a proceeding to explore whether it should modify its radiofrequency exposure standards stating, “we specifically seek comment as to whether our current limits are appropriate as they relate to device use by children.” Over 900 submissions have been made to the FCC. To date no actions have been taken by the FCC or any other Federal agency on this docket. Dr. Moskowitz catalogued Submissions in 2013 on his SAFER EMR website but substantial new submissions have been made. To access all current submissions go to the FCC’s web site for Proceeding Number 13-84.

2012 Government Accountability Office (GAO) Report: “Exposure and Testing Requirements for Mobile Phones Should Be Reassessed.”

This Report  calls on the FCC to “formally reassess and, if appropriate, change its current RF energy (microwave) exposure limit and mobile phone testing requirements related to likely usage configurations, particularly when phones are held against the body,” because without such a reassessment, the “FCC cannot ensure it is using a limit that reflects the latest research on RF energy exposure.” GAO 2012 Report: Exposure and Testing Requirements for Mobile Phones Should Be Reassessed

January 2009, The President’s Cancer Panel Presented on Cell Phone Radiation

This meeting was the last in the President’s Cancer Panel’s  2008/2009 series, Environmental Factors in Cancer and was focused on radiation exposures as they relate to cancer risk. Presenters included Dr. Martha Linet, Chief of the Radiation Epidemiology Branch of the National Cancer Institute, and Dr. David Carpenter, Director of the Institute for Health and the Environment as well as Professor of Environmental Health Sciences within the School of Public Health at the University at Albany. “The evidence for a direct relationship between power line frequency EMFs and cancer is very strong. The lack of a specific mechanism is not a good reason to ignore this evidence.” “The United States needs to take a stand in issuing warnings about the use of cell phones, especially by children. Other countries have taken a precautionary approach with this issue and are basing their warnings on the same science available in the U.S.”

PRESIDENT’S CANCER PANEL MEETING SUMMARY, ENVIRONMENTAL FACTORS IN CANCER. Dr Carpenter’s testimony to the President’s panel was published in Reviews in Environmental Health 2009.

January 2008: National Research Council Report “The Identification of Research Needs Relating to Potential Biological or Adverse Health Effects of Wireless Communications Devices”  

This Report reviewed the research needs and gaps and called for the critical need to increase our understanding of any potential adverse effects of long term chronic exposure to RF/microwave energy on children and pregnant woman. “The Identification of Research Needs Relating to Potential Biological or Adverse Health Effects of Wireless Communications Devices”

2003: The Interagency Radio Frequency Workgroup’s Letter to CK Chou on Additional Concerns about US RF Exposure Guidelines.  

EPA’s Norbert Hankin penned the federal RFIWG’s second letter on concerns about RF human exposure guidelines with three additional issues.; the sensitivity of different tissues to temperature; that a relaxation of  standards will allow for higher exposures; and that the pinna- or ear-  is being considered an extremity and will be allowed far higher RF limits without considerations of different body sizes. To our knowledge neither the 2003 or 1999 letter were ever responded to. Read the 2003  Interagency Radio Frequency Workgroup’s Letter to CK Chou on RF Exposures.

2002 Letter from the EPA about the Inadequacy of the FCC guidelines sent to Janet Newton.

“The generalization by many that the guidelines protect human beings from harm by any or all mechanisms is not justified.”Norbert Hankin,  lead scientist of the EPA Center for Science and Risk Assessment Radiation Protection Division, states that the current FCC human exposure limits, “are thermally based, and do not apply to chronic, nonthermal exposure situations” and that an understanding of the impact on sensitive populations such as children, pregnant women and the elderly still needs to be done. Read the EPA July 6, 2002 Letter on RF Exposure Limits.

2001: Scientist George Carlo Publishes Expose on Wireless Industry

George Carlo is the scientist who lead a 7 year,  28.5 million dollar research project called the Wireless Technology Research ( WTR)  funded by the US wireless industry. When research findings found biological effects such as genetic damage in human blood as measured through the formation of micronuclei, he alleges the information was suppressed and the wireless industry tried to discredit him. He shared his story in a book co-authored with Martin Schram called Cell Phones: Invisible Hazards In the Wireless Age. In addition the volume Wireless Phones and Health II: State of the Science 2002 nd Edition assembles papers presented at WTR’s Second State of the Science Colloquium and is the result of the 28.5 million dollars research program. “The current science is not definitive about health risks from wireless phones; however, the legitimate questions about safety that have arisen from recent studies make claims of absolute safety no longer supportable”. Watch the C-Span Interview with Dr. Carlo.

2001 GAO Report: Research and Regulatory Efforts on Mobile Phone Health Issues

“For its part, FCC makes information on radiofrequency exposure issues publicly available, but this information is typically at a level of technical detail that is not well-suited to a general audience. These shortcomings in consumer information are a particular cause for concern because the industry is including information from both FDA and FCC with most new mobile phones. This report makes recommendations to FCC for improving its review of mobile phone testing and to FCC and FDA for improving consumer information on radiofrequency exposure and health issues….Given the prominence of the mobile phone health issue, FDA and FCC need to provide the public with clear, accurate, and timely information so that they can make informed decisions.” Read the May 2001 GAO Report here.

1999: Federal Radio -Frequency Interagency  Workgroup (RFIW) Letter to Richard Tell Chair, IEEE SCC28 (SC4) Risk Assessment Work Group from the Radiofrequency Radiation Interagency Work Group on Critical Concerns About RF guidelines.

In this letter, members of the RFIW identity several critical  issues with the RF exposure guidelines. Their concerns include the need for a biological basis for SAR limit and they point out that the limits for brain and bone marrow should be lower than those from muscles and fat as tissues are not equally sensitive. They question the selection criteria for the adverse effect and state there is extensive data on acute effects but that the lower-level non-thermal chronic exposure effects may be very different and chronic effects need to be accounted for. They state the uncertainties in the data should be addressed. “These studies have resulted in concern that exposure guidelines based on thermal effects, and using information and concepts (time-averaged dosimetry, uncertainty factors) that mask any differences between intensity-modulated RF radiation exposure and CW exposure, do not directly address public exposures, and therefore may not adequately protect the public.” Read the 1999  Federal Radio -Frequency Interagency  Workgroup (RFIW) Letter to Richard Tell

1998 National Institutes of Environmental Health Sciences (NIEHS) Categorizes EMFs as “Possible” Human Carcinogens.  

Power frequency electromagnetic fields (EMFs) are categorized as “possible human carcinogens,” according to a working group assembled by the National Institute of Environmental Health Sciences (NIEHS). After ten days of review, on June 24, the 30-member panel voted 19 to 9 in favor of categorizing extremely low frequency (ELF) EMFs, such as those from power lines and electrical appliances, as possible carcinogens.

1996 Guidelines for Human Exposure to Radiofrequency Radiation Adopted by the Federal Communications Commission (FCC) Limits

IEEE/ANSI C95.1 1992 were the basis of the FCC regulated exposure limits with some minor points coming from the NCRP Report 86 (1986 Report). Read the FCC Report and Order Guidelines for Evaluating the Environmental Effects of Radiofrequency Radiation ET Docket No. 93-62


This Bill significantly defunded the EPA Radiation Division that was engaged in research and developing safety standards to protect the public from thermal and non-thermal biological effects. The Senate Appropriations Committee Bill states,” …EPA has pursued a number of unintegrated activities on EMF that are of questionable value. Therefore, the Committee believes EPA should not engage in EMF activities.”

1995 EPA Briefing To the FCC and NTIA on EPA “Development of RF/MW Radiation Guidelines”

In this powerpoint presentation, the EPA briefs the FCC and NTIA about their progress in developing human exposure guidelines- that consider thermal AND nonthermal effects for microwave radiation. The EPA was in a two phase process. First they were setting “interim RF radiation guidelines” which “did not account for modulation, chronic exposure or non thermal effects.” Then they were going to focus on “modulated and nonthermal exposures” in Phase 2 by convening national experts. A year later, the EPA was defunded from RF work and standards were never set. EPA Briefing To the FCC and NTIA on EPA “Development of RF/MW Radiation Guidelines

1995: Extremely Low Frequency Electric and Magnetic Fields by the  National Council on Radiation Protection and Measurements (NCRP) Draft Report

NCRP was contracted by the EPA  in 1983 to conduct a review of the biological effects of Extremely Low Frequency (ELF) EMFs. According to Microwave News , the 800 page draft report was prepared which generally endorsed a 2 mG exposure limit. Committee chair Dr. Ross Adey, of the Veterans Administration Hospital in Loma Linda, CA, told Microwave News, “It took us nine years but we finally reached agreement,” The recommendations “would take effect immediately for new day care centers, schools and playgrounds, as well as for new transmission lines near existing housing.”

In July 1995 the NCRP committee Chairman, Ross Adey, stated,“The laboratory evidence for athermal effects of both ELF and RF/MW fields now constitutes a major body of scientific literature in peer-reviewed journals. It is my personal view that to continue to ignore this work in the course of standard setting is irresponsible to the point of being a public scandal.” However on October 11, 1995 NCRP put out a press release that “Draft material formulated by NCRP Scientific Committee 89-3 on ELF EMF has been improperly disseminated and does not reflect NCRP recommendation.” The final report was supposed to be approved and to be publicly available in early 1996, but final approval of the draft has never been acted upon.

1994 (U.S.) Air Force Material Command, Rome Laboratory Report: Radiofrequency / Microwave Radiation Biological Effects and Safety Standards: A Review

“It was recognized that the SAR does not encompass all of the important factors necessary to determine safe exposure levels. The modulation frequency and peak power of the incident EM field should also be considered. Some of the investigators warned that extra care should be taken by persons that are subjected to pulsed EM fields or by fields that are modulated near the whole-body resonance frequency.”“Nonresonant pulsed RF/MW radiation may be more harmful to living organisms than CW radiation emitted at nonresonant frequencies.” “Even exposure to low levels of RF/MW radiation can impair immunologic functions.” (U.S.) Air Force Material Command, Rome Laboratory Radiofrequency / Microwave Radiation Biological Effects and Safety Standards: A Review

1993  EPA Comments to the Federal Communication Commission’s (FCC’s) proposed RF/MW radiation limits 93-142 Guidelines For Evaluating the Non Thermal Effects of Radiofrequency Radiation:

The EPA states that certain subgroups are more at risk (pregnant women, children and the elderly) and calls for an  updated, comprehensive review that considers the biological effects of RF, specifically pointing to the need to update the NCRP Report 86 (Note: NCRP 86 is still the basis for US regulations according to the FCC  and has not been updated to include biological effects).

“The FCC should not adopt the 1992 ANSI IEEE standard there are serious flaws in the standard that call into question whether the proposed use the 1992 ANSI IEEE is sufficiently protective.” The report also states that “the claim of protection for all persons from all interactive mechanisms”  has “not been supported”.  Read the letter and comments  here.

1990 EPA Evaluation of the Potential Carcinogenicity of Electromagnetic Fields (Draft Report)

When this report was first drafted, the team recommended that power-frequency EMFs should be classified as “probable human carcinogens” and that RF/MW radiation be considered a “possible human carcinogen.” However, this review remains a “Draft only” as it was never finalized. The Report was prepared to review and evaluate the available literature on the potential carcinogenicity of electromagnetic fields. With respect to human epidemiologic studies, the EPA found of the strongest link between exposure to 60 HZ magnetic field and human cancer. Consistent modest elevations of cancer risk for leukemia, cancer of the central nervous system and lymphoma were found in children whose exposure to magnetic fields was estimated at two MG or higher. These studies estimate a potential 1.5 to 3 increase in cancer risk from elevated magnetic field exposure as defined by wiring codes.

1989: Biological Effects of Power Frequency Electric and Magnetic Fields Background Paper: US Congress Office of Technology Assessment of Electric Power Wheeling and Dealing: Technological Considerations for Increasing Competition

“In the long run, better scientific understanding is the only way to resolve problems posed by power frequency fields. Yet funding for field-effects research has been irregular over the years and current levels of federal support are modest.” “There is a risk of becoming too fixed on cancer as a single health effect of concern. The breadth of cellular and animal findings suggest that other public health effects, including psychological effects such as chronic depression, deserve some attention.” 1989: Biological Effects of Power Frequency Electric and Magnetic Fields Background Paper

1984: US Science Advisory Board (SAB) Recommendation to the EPA To Develop RF Guidelines:

In this letter, the  SAB Board recommends that the EPA develop radiation protection guidance to protect the public. The report contains a 1983 letter from FCC Chairman Mark Fowler to the EPA Administrator Kathleen Bennett  which states, “We believe that a definitive federal standard is imperative. Therefore we would like to make clear our support for your guidance development. We encourage the EPA to complete this process as expeditiously as possible so that her uniform federal standard will be available for use by the FCC and other affected agencies.”

1983 The EPA publishes Biological Effects Of RadioFrequency Radiation.

“The objective of this report was to summarize and evaluate the existing database for use in developing RF radiation exposure guidance for the general public. The frequency range covered in this document is .5 MHz to 100 GHz. The existing database provides sufficient evidence about the relation between RF radiation exposure and biological effects to commit development of exposure limits to protect the health of the general public. It has been concluded from this review that biological effects occur at SAR up to about 1 W/kg some of them may be significant under certain environmental conditions.” Read the Biological Effects Of RadioFrequency Radiation.

As a result of this hearing, the June 1981 Report “Requirements for an Effective National  Nonionizing Radiation Measurement System” was prepared which provides a detailed assessment of the capabilities, limitations, and requirements of the National Non-ionizing Radiation measurement system. The report concludes that “the need to develop and improve instrumentation, measurement standards, calibration services and standardize measurement techniques far outweighs the need to establish regional calibration laboratories at this time.”

1979: United States Congressional Hearing “Research on health effects of nonionizing radiation” House Committee on Science and Technology. Subcommittee on Natural Resources and Environment. Hearing dated July 12, 1979.

“There is only one established mechanism which can explain most of the effects of non-ionizing radiation and that mechanism is gross heating resulting from exposure to high levels of NIR(nonionizing radiation).” and “There is an increasing number of research reports which describe biological effects and exposure levels that are not commensurate with the induction of gross heating. One may cite a large number of Soviet and East European reports as examples. These results suggest that non-ionizing radiation may cause biological effects without producing significant increases in temperature in sensitive tissue. The possibility of such interactions is being pursued by US researchers.”  (page 195).

1979 FCC Notice of Inquiry on the “responsibility of the FCC to consider biological effects of radiofrequency radiation when authorizing the use of radiofrequency devices”.  

This report details “the considerable differences of opinion about the biological effects of low level and long-term radiation”. “A balance must be achieved between serving the public interest by fulfilling it’s needs for communications services and adequately protecting the populace against potentially adverse biological effects that may be attributable to excessive RF radiation.” The FCC calls for information and data on several matters related to this issue including:

“Does a health risk no matter how small, outweigh economic loss or service cutbacks, no matter how large? By how much? Quantify your contention. Does a health risk to animals have to be considered? What if the species being threatened is on the endangered species list?”
