A Report on Non-Ionizing Radiation

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.

A court in El Paso, TX, ruled on January 26 that German soldiers who developed cancer after being exposed to X-ray radiation from radar components can pursue their claims against the manufacturers of the equipment, according to the German edition of the Deutsche Welle. The defendants include GE, Raytheon and Lucent.

The U.S. military continues to investigate what might happen if you were zapped by one of its microwave weapons. Active denial technology, as the military calls it, uses 94 GHz millimeter waves (MMW) to induce pain by heating the skin. The Marine Corps says it’s like touching “an ordinary light bulb that has been left on for a while” —in fact, it’s just a “harmless energy beam,” according to the marines. Not everyone agrees.

Danish researchers have found no support for Lennart Hardell and Kjell Hansson Mild’s contention that mobile phones increase the risk of acoustic neuromas. A team led by Christoffer Johansen of the Danish Cancer Society in Copenhagen compared the histories of 106 cases of acoustic neuromas, benign tumors of the cranial nerve, with those of 212 controls. There was no elevated rate of cancer, even among those who had used a cell phone for ten years or more.

Apple has released the RF exposure numbers —SARs, or specific absorption rates— for its new Series 3 Watches. These are the first wristwatches that can connect to cellular networks without being tethered to an iPhone.

The highest exposures, according to Apple, occur when the new watches are placed next to the head. The SAR measurements are based on a 10mm separation distance. The Model A1860 entails the highest exposure: 0.53 W/Kg averaged over 1g of tissue (0.52 W/Kg for the A1861).

The National Toxicology Program (NTP) will release the “complete results” of its $25 million project on cell phone cancer risks early next year, according to a statement posted on its Web site yesterday.

“The complete results from all the rats and mice studies will be available for peer review and public comment by early 2018,” the NTP states. The animals were exposed to GSM or CDMA radiation for two years before they were sacrificed...

The incidence of glioblastoma multiforme (GBM), the most virulent and deadly type of brain cancer, is going up in the U.K., while the incidence there of other types of malignant brain tumors are declining, according to some newly published raw data.

Take a look at the two plots below and the trends are immediately apparent.

The incidence rates are not corrected for age, or...

One common criticism of the new NTP cell phone cancer study is that, unlike the male rats, there was no significant increase in tumors among female rats.

For instance in its latest assault on the NTP results, the New York Times is running a comment by a pediatrics professor in Indiana, in which he states:

“It’s also odd that...

This evening, the National Toxicology Program (NTP) released a draft of the report on its two-year cell phone cancer study. Linda Birnbaum, the director of the NIEHS, and John Bucher, the leader of the study, will present the report at a teleconference tomorrow, Friday. They are the director and associate director of the NTP, respectively. [Birnbaum did not...

Weak RF fields may indeed be able to promote cancer, according to two leading members of the EMF/RF research community. Frank Barnes and Ben Greenebaum are offering theoretical arguments to explain how low-level RF radiation can alter the growth rates of cancer cells. They present their ideas in an article which has just...
