New peer-reviewed letter presents scientific case for retraction of conclusions of 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.
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.

Follow-Up Research on NTP’s Clear Evidence on RF Causing Malignant Tumors in Rats

Lin JC. Follow-Up Research on NTP’s Clear Evidence on RF Causing Malignant Tumors in Rats [Health Matters]. IEEE Microwave Magazine. 25(6):16-18. June 2024. doi: 10.1109/MMM.2024.3378608.
The recent disclosure of the U.S. National Toxicology Program (NTP) closing down its RF radiation research program on how RF radiation causes cancer was a surprise [1], [2], [3]. NTP is a part of the National Institutes of Health and reports to the U.S. Department of Health and Human Services. NTP’s mandates are to provide the scientific basis for programs, activities, and policies that promote health or lead to the prevention of disease.
In 2018, NTP published the final report on its US$30 million laboratory research showing “clear evidence” that lifelong exposure to low-level RF radiation caused cancers in rats [6], [7], [8]. The statistically significant findings showed that both GSM- and CDMA-modulated 900-MHz RF radiation had led to the development of malignant schwannoma, a rare form of tumor in the hearts of male rats. Furthermore, an independent analysis of the NTP data for overall cancer incidence detected in any organ or tissue inside the animal showed that rats exposed to GSM and CDMA cellphone RF radiation had significantly higher overall or total primary tumor incidence than the concurrent controls….
The NTP findings of clear evidence that RF radiation can cause cancer was already reaffirmed by the Ramazzini Institute study from Italy [10]….
In 2019, NTP announced a new genotoxicology project designed to examine how RF radiation causes cancer….
Apparently, now, close to five years later, the new project has never progressed beyond the feasibility studies with the compact exposure chambers. Moreover, the NTP located in Research Triangle Park, NC, USA, no longer plans to study biological effects from cellphone RF radiation. NTP has decided that “the research was technically challenging and more resource-intensive than expected.” This effectively marks the end of the nonmilitary governmental project in the United States to study the biological effects of cellphone or RF radiation. Any future NTP publications on the topic would come from the feasibility studies only [3].
Unfortunately, whether the U.S. civilian government halts doing the important research on mechanistic causes for cancer from low-level chronic exposure to RF radiation or not, nearly 100% of all Americans are being cast as subjects in a massive health experiment without a formal protocol. Furthermore, billions of people worldwide, including the young and older adults, are being exposed to unnecessary levels of human-made wireless RF radiation.
The obvious question is, what happened? Should we all forget about NTP’s findings of clear scientific evidence that lifelong exposure to low-level RF radiation causes cancer from a federal government health agency that prides itself in telling the nation that its product is “science you can depend on for decisions that matter”?
Postscript: It is interesting to recall that the recently announced termination of NTP’s RF research program on how RF radiation causes cancer practically halts most, if not all, biological research of RF radiation supported by the civilian U.S. government. In contrast, the military arm of the U.S. government through its Defense Advanced Research Projects Agency (DARPA) has initiated a new research program on the roles RF radiation may have in biological systems [11]. DARPA’s historical and contemporary contributions to scientific and technological advancements are widely known. Thus, it poses the question, what does DARPA know about RF radiation on biological systems?

Some Italian regions place moratoriums on 5G deployment pending safety studies.

A dutiful application of the Principle of Responsibility, Precautionary and Good Policy should have led the Public Defender to change the limits of radiofrequency electromagnetic radiation only as a result of a rigorous verification of the effects of 5G technology…

Letter to Italian officials (English)

Microwave news reports, on March 13, 2024, the International Commission on the Biological Effects of Electromagnetic Fields sent a letter to Italian public officials critical of the new law it passed on December 30, 2023, increasing the Italian radiofrequency radiation human exposure limits. For over two decades, Italy has had a lower exposure threshold. ICBE-EMF expressed support in this letter for the 6×6 Network, a collaborative Italian advocacy group, composed of scientists, physicians, advocacy groups and citizens, who have organized in opposition to oppose the new law.

Promised Studies on Mechanisms Never Done

The U.S. National Toxicology Program (NTP) has closed down its RF radiation research program. Indeed, it appears that work effectively stopped some time ago.

Why did NIH abruptly halt research on the harms of cell phone radiation?

by Devra Davis, Opinion Contributor – 02/01/24 8:00 AM ET

In a shocking reversal, the National Toxicology Program (NTP) of the National Institute of Environmental Health Sciences has quietly disclosed that it will stop studying the biological or environmental impacts of cell phone radiofrequency radiation.

Brain Tumor Rates Are Rising in the US: The Role of Cell Phone & Cordless Phone.

Head and neck tumors associated with cell phone use have increased in the U.S. since 2000

Electromagnetic Radiation Safety, Feb 1, 2024

Since the year 2000, the U.S. has experienced significant increases in the age-adjusted incidence rates of four head and neck tumors associated with cell phone use, including the most serious malignant brain tumor (glioblastoma), a non-malignant tumor on the outer covering of the brain (meningioma) and cancers of the salivary and thyroid glands. Among youth less than 20 years of age, nonmalignant meningioma and thyroid cancer significantly increased.

It was among his many letters, notes and clippings I had stashed away over the last 50 years…

Cell phone radiation exposure limits and engineering solutions

Published: April 4, 2023

Summary Statement
This paper details six low-cost engineering fixes that could dramatically reduce cellphone radiation. The paper also discusses seven blind spots in the way we have set emissions standards for cellphones. Those blind spots suggest that current standards are inadequate and that no one can be assured that cellphones on the market today are safe.
