Henry Lai: Microwave News Article Archive (2004 - )

Narendra P. Singh, known to friends and colleagues simply as NP, died last December at the age of 69. When his family wrote to me with the news, Singh’s wife asked me not to publish a tribute or an obituary at that time. I honored her request, but now, after a decent interval, I break my silence, in part to make good on a promise and to settle some unfinished business.

Singh was a proud and honest man; he was also gentle and unassuming. “He cannot tell a lie, even a white lie,” Henry Lai, his long-time collaborator at the University of Washington in Seattle, told me years ago. Perhaps most of all, Singh was a meticulous experimentalist who believed in the power of science.

Arthur W. Guy, known to all as Bill, died on April 20^th at the age of 85. Guy will be best remembered as the leading proponent of the use of specific absorption rates (SARs) as a way of measuring the radiation dose associated with RF/MW exposure.

Guy received a doctorate in electrical engineering in 1966 from the University of Washington, Seattle, and then joined the UW faculty where he remained until his retirement in 1991. He stayed active as a consultant over the next 15 years. He served as a prominent...

A well-regarded and influential team of researchers from the National Institutes of Health (NIH) and the Brookhaven National Lab (BNL) is on the brink of resolving a long-standing dispute with enormous implications for public health. In a paper due out tomorrow, Nora Volkow and coworkers are reporting that cell phone radiation can affect the normal functioning of the human brain.

Whether these short-term changes will lead to health consequences (and what they might be) is far from clear — though Volkow already has preliminary indications of a long-term effect. Nor is the mechanism of interaction yet known. But the new finding, if confirmed, would at the very least force a rethink of the prevailing orthodoxy, which maintains that low levels of RF and microwave radiation are too weak to have any effect and can be disregarded.

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."

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.

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.”

If you had any doubts that the wireless industry is in total control of the RF health debate, you need only to have gone to the workshop held at the FCC’s Washington headquarters on June 28. By the end of the day, the fog would have lifted.

Motorola’s Joe Elder told the assembled delegates from the U.S., the EU, Japan and Korea that the health issue is just about settled. There is no credible evidence that casts doubt on the current 4 W/Kg threshold for ill effects from mobile phone radiation, he said.
