A Report on Non-Ionizing Radiation

News & Comment

Monday, August 14, 2006

Scientists from New Zealand, the U.K. and Finland are worried about a different kind of electromagnetic weapon: One that could wreck havoc with the world's communications systems —think HAARP run by a Herman Kahn wannabe. Check out the press release issued today by the University of Otago. For background, see "Nuclear Explosions in Orbit," a feature article originally published in Scientific American.

Microwave weapons for crowd control used to be top-secret stuff. No more. Raytheon, which makes them for the military, now promotes its Silent Guardian, a smaller version of its Active Denial system (see MWN, M/A01, p.1), on the Web. Silent Guardian is "available now and ready for action," Raytheon promises. The company even discloses its range, which used to be closely held. It can "de-escalate aggression" at 250 yards, Raytheon states in its best defense-speak. To tempt you further, you can also download a 30-second video, with an up-tempo soundtrack.

The trend continues. The August issue of Radiation Research is out and it has two papers on the possible effects of RF/microwave radiation, one from Finland and one Sweden. In each case, no effects were found. (See our July 31 post.)

The incidence of malignant tumors on the two top floors of a high-rise buildingat RMIT University in Melbourne, Australia, are within the expected range, according to reports released today.

When benign tumors are included, however, the total tumor count is statistically higher than expected. Southern Medical Services, which carried out the occupational health and safety assessment for RMIT, attributes the "apparent increase" to incomplete collection of benign tumor data by the cancer registry.

The reports, together with RMIT public statements, are available from the RMIT Web site. (See also our posts of June 1 and before.) Southern Medical Services, found that "there is no correlation between tumor case office locations and ELF magnetic fields greater than 4 mG."

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.

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.

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.

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.

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.

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.
