A Report on Non-Ionizing Radiation

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.

It's the strongest warning yet. John Aitken, a well-known fertility researcher, is advising men who want to have children not to keep active mobile phones below their waists. This issue, he says, "deserves our immediate attention."

Getting a handle on EMF and RF effects is a frustrating business. A new paper in the March 9 issue of Mutation Research from Finland's University of Kuopio tells the story. The Kuopio research group found that mobile phone radiation, at 5W/Kg, can amplify the DNA damage caused by a chemical mutagen. This is far from the first time an RF-induced genotoxic effect has been reported (see our September 3, 2008 post).

This could be a breakthrough, a major breakthrough. It could explain how power lines promote childhood leukemia. It could identify which children are at greatest risk. And it could shed new light on the pivotal role played by EMF-induced DNA breaks.

Chinese researchers have found that children who carry a defective version of a gene that would otherwise help repair damaged DNA are much more likely to develop leukemia if they also live near power lines or transformers. Xiaoming Shen and coworkers at the Jiao Tong University School of Medicine in Shanghai have reported that children with this genetic variant —known as a polymorphism or snp (pronounced "snip") —and who lived within 100 meters of these sources of EMFs had over four times more leukemia than neighboring children with a fully functional version of the same gene.

Research scientists in China have found that relatively low-level RF radiation can lead to DNA breaks, according to a briefing paper prepared for the cell phone industry obtained by Microwave News.

At the 4th International Seminar on EMFs and Biological Effects, held in Kunming China, September 12-16, Zhengping Xu of the Zhejiang University School of Medicine reported that cells exposed to a pulsed 1800 MHz RF radiation at an SAR of 3 W/Kg for 24 hours showed a statistically significant increase in DNA damage. The Mobile Manufacturers Forum (MMF), an industry lobbying group based in Brussels, circulated the news in a September 22 Research Briefing.

Bill Guy says that he didn’t do it, that he didn’t call NIH, that he didn’t try to shut down Henry Lai’s work on microwave-induced DNA breaks. (See "Wake-Up Call.")

In a letter to Microwave News, Guy wrote: “I most vehemently and unequivocally deny that I, or anybody that I am aware of, made any calls to NIH...”

The March issue of the University of Washington alumni magazine, Columns, features a well-deserved tribute to Henry Lai and his colleague, N.P. Singh, who have demonstrated that low-level microwave radiation can lead to an increase in DNA breaks in the brain cells of rats (available online). The headline of the piece tells the story: “Wake-Up Call: Can Radiation from Cell Phones Damage DNA in Our Brains? When a UW Researcher Found Disturbing Data, Funding Became Tight and One Industry Leader Threatened Legal Action.”

The ability of ELF magnetic fields to damage DNA may be getting clearer (see item below) —but not so for microwaves. Over the last ten years, the battle of the Washington universities has been raging, with Joseph Roti Roti of Washington University in St. Louis at odds with Henry Lai and N.P. Singh of the University of Washington, Seattle. Roti Roti is now claiming the upper hand in the February issue of Radiation Research.

Environmental Health Perspectives will publish a new paper by Henry Lai and N.P. Singh showing that a 24-hour exposure to 100 mG ELF EMFs can lead to significant increases in single- and double-strand DNA breaks. The two University of Washington, Seattle, researchers found even larger increases following a 48-hour exposure, leading them to conclude that the effect is cumulative.
