A Report on Non-Ionizing Radiation

"Are there any biological effects that are not caused by an increase in tissue temperature (nonthermal effects)?" That was one of the "overarching issues" considered by the NAS-NRC committee at the workshop it hosted last August (see p.11 of the its final report, as well as our August 10, 2007 and January 17, 2008 posts). At the time, France's Bernard Veyret, the member of the committee who led the discussion, expressed skepticism that such effects had been reliably documented.

Nancy Wertheimer, who more than any other epidemiologist was responsible for identifying the association between magnetic fields and childhood leukemia, died at the age of 80 on Christmas day. The cause was complications following hip replacement surgery, according to Ed Leeper, her life partner and long-time collaborator.

Committee Told Not To Include Them

The NAS-NRC report, released today (see our January 15 post), presents a laundry list of research needs to better understand the possible health effects of RF radiation. What’s missing is any sense of priorities. The NAS-NRC committee that prepared the report fails to indicate whether characterizing a child’s exposure from a cell phone is more important than doing an epidemiological study of children who use them; or whether mechanistic studies are more important than laboratory toxicology experiments.

On Thursday, January 17, the U.S. National Academy of Sciences-National Research Council (NAS-NRC) will release its report on what types of research, if any, are needed to address potential health effects of radiation used for wireless communications.

The report, which was requested by the FDA's Center for Devices and Radiological Health (CDRH), marks the closing chapter of the cooperative research agreement (or CRADA) between the CTIA, the trade association of the cell phone and wireless industries, and the CDRH.

Two New Papers Show Effects

January 9, 2008

It's a new year and maybe, just maybe, it signals a new outlook at Radiation Research, a journal with a reputation for publishing negative findings (see, for instance, "Radiation Research and The Cult of Negative Results.")

PERFORM-A is a washout. The eight-year, $10 million industry research project that was supposed to answer the question, "Does cellphone radiation cause cancer in animals?" instead promises to sow more confusion and mistrust.

Another reader has brought to our attention a fourth paper showing that GSM radiation can alter sleep. James Horne and coworkers at the Sleep Research Centre at Loughborough University in the U.K. have reported that very weak (0.133 W/Kg) signals can delay sleep onset. The new work, published in June, raises some particularly important —and thorny— issues regarding the biological effects of different ELF modulations on the 900 MHz GSM pulses. We'll leave those for another time, but for now the Loughborough study reinforces the take-home message that RF effects on sleep have become a major focus of the mobile phone health controversy.

The ability of mobile phone radiation to affect sleep is emerging as a robust low-level effect.

A team led by Bengt Arnetz has reported that a three-hour exposure to GSM radiation at 1.4 W/Kg an hour before bed can disrupt sleep. This supports the findings of Peter Achermann of the University of Zurich and Sarah Loughran of the Brain Sciences Institute at Australia's Swinburne University.

The five U.S. cell phones with the highest SARs are all made by Motorola, according to a list compiled by CNET. One Moto phone, the V195s for T-Mobile, has an SAR of 1.6 W/Kg, which is the maximum level allowed by the FCC (this model is not included on Motorola's SAR Web site). On the other hand, Moto's Razr V3x had the second lowest SAR (0.14 W/Kg) on CNET's list —though this model is not available in the U.S. Motorola's Web site gives the V3x as having a maximum SAR of 0.58 W/Kg.

Why is the Interphone study not finished yet? "The interpretation is not straightforward," Elisabeth Cardis told Microwave News in an interview from her office at IARC in Lyon, France. The data are "very difficult to interpret because of the potential problems of recall and selection bias," she explained.
