RF animal studies: Microwave News Article Archive (2004 - )

We’re all frazzled and anxious. The world has changed, seemingly overnight, and we don’t know when and how we will ever go back to normal —whatever that means. One thing we don’t have to worry about is whether 5G radiation is responsible for COVID-19. It’s not. There’s no credible evidence to suggest otherwise.

Yet, there is at least one important parallel between how we’ve been struggling with COVID-19 over the last few months and how we have been dealing with electromagnetic radiation for the last few decades. In each case, science has taken a back seat to politics.

“Evaluation of the NTP and Ramazzini Studies,” BERENIS Newsletter, November 2018.

This expert group on EMF/NIR, which advises the Swiss Federal Office for the Environment, states that these two animal cancer studies are “the most comprehensive” to date. Despite their methodological differences, they both showed “relatively consistent results in schwannomas and gliomas, as well as a dose-dependent trend to an increase in the carcinogenicity of these tumors.” Based on these findings, BERENIS favors a precautionary approach for RF/EMF exposures.

The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has determined that the two recent animal studies pointing to a cancer risk from cell phone radiation are not convincing and should not be used to revise current exposure standards. 

In a “note” published today, the 12-member group states that the studies by the National Toxicology Program (NTP) and...

Partial results of the Ramazzini Institute’s RF–animal study, which show a statistically significant increase in tumors in the hearts of male rats exposed to GSM radiation, were officially released today. They appear in Environmental Research, a peer-reviewed journal.

As we reported last month, the Ramazzini finding of Schwann cell tumors —called schwannomas— in the rat hearts is consistent with a similar finding by the U.S. National Toxicology Program (NTP) in a $25 million RF project.

In an interview with Microwave News, Fiorella Belpoggi, the senior author of the new paper and the director of the Ramazzini Institute’s Research Center in Bologna, Italy, offered her views on the new results, the parallels with those of the NTP and the implications for IARC’s designation of the cancer risk of RF radiation.

Here are four key takeaways from the NTP press conference held this afternoon, soon after the release of its two cell phone reports [these are no longer available]:

1. NTP’s bottom line on cell phone use: “This is not a high-risk situation.”

2. RF radiation has biological effects at levels previously believed to be innocuous —they may be good or bad.

3. NTP will continue to do RF health studies. A new exposure facility is being built on the NIEHS campus, which will be smaller and more flexible than the one used for...

“Two-Year Oncogenicity Evaluations of Cell Phone RF Radiation in Sprague-Dawley Rats and B6C3F1 Mice,” Toxicology Letters, Supplement 1, October 20, 2017.

“Considering (a) the conflicting results of RF epidemiology studies and (b) the lack of generally accepted biophysical or molecular mechanisms through which RF could induce or promote neoplasia, data from animal bioassays will play a central role in ‘weight-of-the-evidence’ assessments of the possible health effects of RF exposure.” Abstract only. By IITRI’s David McCormick, who ran the exposures for the NTP–cell phone cancer study.

“Evaluation of the Genotoxicity of Cell Phone RF Radiation in Male and Female Rats and Mice Following Subchronic Exposure.” NTP paper presented at Environmental Mutagenesis and Genomics Society annual meeting, September 9-13, 2017.

“[E]xposure to RFR has the potential to induce measurable DNA damage.” More here and here.

The National Toxicology Program (NTP) has changed course and will not —at least for the time being— publish its findings of increased DNA breaks among rats exposed to cell phone radiation as a stand-alone paper.

The DNA study, which is part of NTP’s landmark experiment showing that RF radiation can lead to tumors in the brains and hearts of laboratory animals, will now be incorporated in NTP’s Technical Report on the $25 million project, the NTP has told Microwave News.

In May, the U.S. National Toxicology Program (NTP) announced that male rats exposed to cell phone radiation developed higher rates of cancer. Soon, the NTP will explain how that might have happened.

The same RF/microwave radiation that led male rats to develop brain tumors also caused DNA breaks in their brains. Female rats —which did not have significant elevated tumor counts— had fewer DNA breaks.

All these findings are part of the same $25 million NTP project.

The NTP results provide “strong evidence for the genotoxicity of cell phone radiation,” Ron Melnick told Microwave News.
