A Report on Non-Ionizing Radiation

News & Comment

A Microwave News Investigation

Monday, July 31, 2006

Radiation Research is a scientific journal whose primary focus is on ionizing radiation, with only a minority of papers devoted to the non-ionizing side of the electromagnetic spectrum. Its June issue, however, features five papers, all of which claim to show that EMFs of one type or another have no biological effects.

Good Exposure Assessment; Poor Participation Rate

Tuesday, July 11, 2006

Magnetic fields have been linked to childhood cancer in many countries and now it's also been shown in Japan. Michinori Kabuto, of the National Institute of Environmental Studies in Ibaraki, along with a number of collaborators have found that children exposed to 4 mG (0.4 µT) or more in their bedrooms had close to five times more leukemia than those living in low-exposure homes. This statistically significant finding appears in the August 1st issue of the International Journal of Cancer.

It's official. Mike Repacholi has left the WHO. The EMF project is now in the hands of Emilie van Deventer. You can reach Mike at mrepacholi@yahoo.com.

Being a member of ICNIRP or the WHO EMF project means having a ticket to ride. A couple of days ago, the traveling road show was in Malta. Mike Repacholi, Bernard Veyret and Paolo Vecchia showed up at a forum organized by the local communications authority, titled "The Reality Behind EMFs."

The RF problem is a result of our misperceptions, according to the WHO's EMF project. The WHO would have us believe that everything would be better if we would just focus on all the good things that wireless technology is bringing into our lives instead of on those trifling health risks. As Mike Repacholi told Gregor Dürrenberger of the Swiss Research Foundation on Mobile Communications: "As technology progresses, people's understanding of it is weak, causing a fear of the unknown, and, in their minds, that EMF health effects may occur from long-term low-level exposure."

RF Animal Cancer Review Is #1

May 7, 2026

A systematic review pointing to evidence that exposure to RF radiation causes cancer in animals has captured the world’s attention.

The review, prepared by an eight-member team from six countries, led by Meike Mevissen of Switzerland’s University of Bern, was commissioned by the World Health Organization in Geneva. It was published by Environment International last April.

A few days ago, the editors of Environment International announced that Mevissen’s review was the journal’s most-downloaded paper of 2025.

NTP Lite: All Good in Korea Too

January 18, 2026
Last updated July 31, 2026

Korean researchers working on NTP Lite have joined their Japanese collaborators in reporting no evidence of adverse effects among rats chronically exposed to cell phone radiation.

“Long-term exposure to CDMA-modulated 900 MHz RF was neither carcinogenic or genotoxic at an SAR of 4 W/Kg in male rats,” Young Hwan Ahn and coworkers write in Toxicological Sciences, the same journal that published the Japanese results a few days ago. The Korean paper was posted on January 16.

NTP Lite: No Cancer Risk Seen in Japan

January 13, 2026
Last updated July 31, 2026

The Japanese team working on a partial repeat of the NTP RF–animal cancer study has reported seeing no “reproducible” effects on cancer or genotoxicity in RF-exposed male rats.

The project —nicknamed NTP Lite— is a scaled-down version of the $30+ million project carried out by the U.S. National Toxicology Program which found “clear evidence” that RF radiation can cause cancer in rats.

The Japanese results were published in the journal Toxicological Sciences yesterday, January 12. The paper is open access.

ElektrosmogReport Now in English Too

February 9, 2025
Last updated March 28, 2025

One of the longest-running newsletters on the health and environmental impact of electromagnetic fields and radiation —the ElektrosmogReport— is now available in English.

Diagnose:Funk, the publisher, is translating the German-language original and making it available at no charge. Both versions come out quarterly. D:F is a consumer and environmental protection group with offices in Germany and Switzerland.

On September 12th, the U.S. National Cancer Institute (NCI) will host a conference on cancer bioelectricity via Zoom. Attendance is free, but registration is required.

Michael Levin, a professor of biology and biomedical engineering at Tufts University in Massachusetts, will be the keynote speaker.

Another WHO RF Review Challenged

August 21, 2024
Last updated January 21, 2025

A third RF systematic review commissioned by the World Health Organization’s EMF Project is under fire. This one is on RF–induced oxidative stress.

Last month, two other WHO reviews —on pregnancy outcomes and on tinnitus— were both called into question as critics called for them to be retracted.

A team of 14 from six countries, led by Felix Meyer of the German Office for Radiation Protection (BfS), identified 11,599 studies on oxidative stress in the frequency range 800-2450 MHz. They then eliminated 11,543 of them as not meeting their criteria for inclusion.
