In today's Wall Street Journal, Carl Bialik, the newspaper's "Numbers Guy," digs into reports from the Netherlands on the effects of Wi-Fi radiation on trees. The headline, "Wi-Fi Threat to Trees Rooted in Shaky Stats," tells the story. Check out also Bialik's accompanying blog entry, "Trees and Wi-Fi May Co-Exist After All."

Monaco, the world's smallest country, now has one the world's toughest RF exposure standards. An ordinance adopted at the end of November requires ambient levels near mobile phone towers not exceed 4 V/m (~4 µW/cm2). For radio and TV towers, the limit is a slightly more lenient 6 V/m. These are about ten times stricter than the limits recommended by ICNIRP. Switzerland adopted a 4 V/m standard for cell towers ten years ago. At the time, the Swiss environmental agency said the standard was an example of the application of the precautionary principle (see MWN, J/F00, p.1).

Lippincott Williams & Wilkins, the publisher, is allowing free downloads of its top radiology papers, at least for a limited time. Number one on the list is "Risk of Brain Tumors From Wireless Phone Use" which appears in the November/December issue of Journal of Computer Assisted Tomography. Use this link for a pdf copy.

For a completely different perspective of the ELF-EMF genotox literature (from ICNIRP's), take a look at a review by an Italian group led by Livio Giuliani. It appears in a just-released monograph, "Non-Thermal Effects and Mechanisms of Interaction Between Electromagnetic Fields and Living Matter," which includes 24 papers (the one on genotoxicity begins on p.123). The entire volume, which was sponsored by ICEMS and the Ramazzini Institute, is a free download. Another important paper in this collection (p.219) is the first published report from the Ramazzini's "mega" animal experiments on EMFs and cancer, directed by Morando Soffritti and Fiorella Belpoggi: It shows that magnetic fields can increase the incidence of breast tumors among rats. Giuliani and Soffritti are the co-editors of the new monograph. ICEMS is positioning itself as a counterweight to ICNIRP. This should not be too difficult given that ICNIRP has lost its way.

After we posted our November 15 Short Take on ICNIRP's failure to cite a host of papers showing genotoxic effects of power-frequency EMFs, we got an e-mail from Kjell Hansson Mild of Umeå University in northern Sweden. "ICNIRP missed many others," he told us. Mild appended a list of eight papers he had been associated with —published between 1984 and 2001, all in peer-reviewed journals. They document DNA and chromosomal breaks in cells, animals (mice and rats) and humans (substation workers and train drivers). No word yet about how ICNIRP missed every single one.

ICNIRP has now posted a copy of its new ELF EMF guidelines (the Health Physics paper), together with an accompanying fact sheet, on its Web site. Both are free downloads.

November 15, 2010

If you want to see just how misguided the ICNIRP enterprise really is, take a look at its new EMF exposure guidelines in the December issue of Health Physics. [See also our November 10 post.]

Start at the end with the footnote that discloses the composition of its five-member ELF Task Group (p.830): Rüdiger Matthes (Germany, chair), Anders Ahlbom (Sweden), Kari Jokela (Finland), Colin Roy (Australia) and Richard Saunders (U.K.). Only one of them has training in any of the biological sciences. Saunders earned his doctorate in zoology and comparative physiology.

All the others except for Ahlbom work on EMF measurements and dosimetry. Ahlbom is an epidemiologist, who spent a good part of his career showing that EMF exposures are associated with childhood leukemia; a finding he now seems to want to repudiate. The absence of a molecular biologist on the task group might be the reason the guidelines all but dismiss the possibility that ELF EMFs can lead to DNA breaks (which could explain the link to leukemia). ICNIRP states that, "Generally, studies of the effects of low-frequency field exposure of cells have shown no induction of genotoxicity at fields below 50 mT" (500 G or 500,000 mG).

This is simply wrong. Totally wrong. ICNIRP has ignored a large body of work published in peer-reviewed journals. One Swedish team, for instance, showed "highly significant" DNA damage at levels as low as 8 µT (80 mG) —an exposure that is 6,250-times lower than 50 mT! Much of this was known more than a decade ago (see MWN, N/D98, pp.9-10.) Just last year, Switzerland's Primo Schär reported significant DNA fragmentation at 1 mT. (See also "Faulty DNA Repair May Explain EMF Role in Childhood Leukemia.")

Is anyone going to hold ICNIRP accountable for these errors and biases?

November 12, 2010

According to the U.K.'s National Grid, here is ICNIRP's new statement on chronic EMF health risks: "It is the view of ICNIRP that the currently existing scientific evidence that prolonged exposure to low-frequency magnetic fields is causally related with an increased risk of childhood leukemia is too weak to form the basis for exposure guidelines. In particular, if the relationship is not causal, then no benefit to health will accrue from reducing exposure" [emphasis added].

At the same time, ICNIRP has doubled the occupational magnetic limit to 10 G (1 mT) and the public exposure limit to 2 G (200 µT).

We will have much more to say about this stunning rejection of precautionary policies in the future [see our November 15 post], but for the moment, we ask: Why did this important news first appear on an EMF Web site run by an electric utility rather than ICNIRP itself? If nothing else, it reinforces the widely-held perception that ICNIRP is a subsidiary of industry. It's high time for full public disclosure on how ICNIRP elects its members and where it gets its money.

A follow-up to our "Scams Galore" piece: Today, the Australian TV show MediaWatch ran an item on the Q-Link scam —"Q Are the Missing Link." Well worth a look. The piece was prompted in part by an item in the Sydney Daily Telegraph promoting the bogus shield (it has now been thankfully removed from the Web). See also ScienceBlogs and a more detailed piece on Crikey.

A potentially important decision: "Cell Phone Liability Lawsuits Pre-empted by FCC, 3rd Circuit Rules" in (item actually dated October 25).
