A Report on Non-Ionizing Radiation

News & Comment

Monday, April 18, 2011

Chinese researchers in Beijing are seeing some of the highest rates of cancer ever reported in any cell phone study. They have found that long-term, heavy users have rates of malignant parotid gland tumors that are seven to 13 times higher than might otherwise be expected.

The International Agency for Research on Cancer (IARC) has invited three industry operatives to sit in on its weeklong assessment of the cancer risks associated with exposure to wireless radiation and other sources of RF/microwave radiation. Representatives from CTIA, the Wireless Association, the Mobile Manufacturers Forum (MMF) and the GSM Association will all be allowed to attend the IARC review. The meeting will be held in Lyon, France, May 24-31.

"Cell Phones Affect Brain Activity." That headline has appeared all over the world since Nora Volkow published a PET scan of a brain lit up by a cell phone last month. Her colorful graphics, published in the high impact Journal of the American Medical Association (JAMA), guaranteed Volkow a large and attentive audience. But all the hoopla shouldn't obscure the fact that for more than a decade many others, notably Peter Achermann's group at the University of Zurich, have shown similar types of radiation-induced changes in the brain as well as much more.

Low-Level Effects Get a Boost

Tuesday, February 22, 2011

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 only a short letter buried in the back pages of a journal, but it could change the entire cell phone–cancer controversy.

A group at Hebrew University in Jerusalem has reported a sharp increase in the incidence of parotid gland tumors in Israel over the last 30 years. Rakefet Czerninski, Avi Zini and Harold Sgan-Cohen found that these tumors have quadrupled since 1970, "with the steepest increase" after 2001 (see plot below). Their letter appears in the January 2011 issue of Epidemiology; it's a free download. They are with the Hadassah School of Dental Medicine at the university.

Here are four key takeaways from the NTP press conference held this afternoon, soon after the release of its two cell phone reports:

1. NTP’s bottom line on cell phone use: “This is not a high-risk situation.”

2. RF radiation has biological effects at levels previously believed to be innocuous —they may be good or bad.

3. NTP will continue to do RF health studies. A new exposure facility is being...

The NTP has released two reports on the cancer risks from cell phone radiation (GSM and CDMA) on rats and mice. They are available here.

The NTP press release, “High Exposure to RF Radiation Linked to Tumor Activity in Male Rats” is here.

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...
