A Report on Non-Ionizing Radiation

A new analysis from the radiation group at the International Agency for Research on Cancer (IARC) calls into question the agency’s own classification of wireless radiation as a possible human carcinogen.

On May 27, IARC’s Isabelle Deltour presented the new analysis of the incidence of malignant brain tumors (glioma) in the Nordic countries —Denmark, Finland, Norway and Sweden— over the last several decades. She spoke at an online colloquium hosted by the German Federal Office of Radiation Protection, known as the BfS.

Deltour argued that the trends are mostly not “compatible” with those seen in the epidemiological studies —principally, Interphone and Lennart Hardell’s— that were the basis of IARC’s 2011 designation of RF radiation as a possible, or 2B, human carcinogen.

“Occupational Exposure to High-Frequency EMFs and Brain Tumor Risk in the INTEROCC Study: An Individualized Assessment Approach,” Environment International, online July 31, 2018.

“In conclusion, despite the improved quantitative exposure assessment used in this study, the results do not support a positive association between occupational exposure to high-frequency EMF and either glioma or meningioma risk. However, given our limited statistical power, due to the small number of exposed participants, and despite our results’ lack of significance our findings foster the need for further research focusing on RF magnetic fields and tumor promotion, as well as possible interactions with other frequencies and with chemicals.” (see press release.)

“Interactions Between Occupational Exposure to ELF Magnetic Fields and Chemicals for Brain Tumour Risk in the INTEROCC Study,” Occupational & Environmental Medicine, posted June 9, 2017.

“There was no clear evidence for interactions between occupational ELF and chemical exposures in relation to glioma or meningioma risk observed.” For more on INTEROCC, go here.

“Investigation of Bias Related to Differences Between Case and Control Interview Dates in Five Interphone Countries,” Annals of Epidemiology, December 2016.

This new analysis found “generally similar results” to the original Interphone study, but with “stronger positive associations among long-term users.”

Canadian Conflict-of-Interest Follies:Anything Goes Except Non-Disclosure

In 2011, Health Canada found itself in a tough spot. The public was becoming more and more uneasy over exposure to RF radiation from the proliferating number of cell phones, cell towers and Wi-Fi routers. After holding hearings in the spring and fall of 2010, Parliament asked the health agency to investigate whether its exposure limits —the Canadian national RF standard known as Safety Code 6 (SC6)— were too lenient and needed strengthening. Soon afterwards, the International Agency for Research on Cancer (IARC) added urgency to the assignment by classifying RF radiation as a possible human cancer agent, or, in the vernacular, a 2B carcinogen.

Health Canada’s dilemma was that it had no interest in tightening SC6. Yet IARC’s 2B designation could not be easily ignored, especially after France and Belgium, among other European countries, had responded by adopting precautionary policies. Last year, for instance, Belgium banned the sale of cell phones to children. How would Health Canada find a way to stick with the status quo?

The answer was to commission a review of SC6 by the Royal Society of Canada (RSC) …

“Federal W-Fi Panel Criticized for Undisclosed Conflict,” Journal of the Canadian Medical Association (CMAJ), June 18, 2013.

On Dan Krewski's C$125,000 contract with Industry Canada and his possible appointment to a Royal Society of Canada panel which will review the country’s RF exposure rules (Safety Code 6). Update: On July 5th, Krewski stepped down from the Expert Panel on Review of Safety Code 6.

Set Interphone Free

It's time to end the deadlock. It's time to release the results of the Interphone study, the largest and most expensive cell phone epidemiological study ever attempted. Any further delay would be close to scandalous.

A draft of the final paper with the combined data from the 13 participating countries was completed close to two years ago. One member of the Interphone team —Canada's Dan Krewski— has said that the holdup is due to disagreements over editing the manuscript, that is, changing a comma here or a comma there. We doubt that what's going on. Krewski told us this close to six months ago and the paper has still not been submitted for publication.

More RF Research in the U.S.? Don’t Hold Your Breath

Don’t hold your breath waiting for the U.S. to do more research on the possible health effects of mobile phones.

After sitting through two and a half days of briefings at this week’s National Academy of Sciences workshop in Washington, we walked away thinking that it’s unlikely that the academy’s report, due by the end of the year, will put a high priority on initiating any new projects. The panel would have to make some strong recommendations to prompt action because, at the moment, the federal government has neither the will nor the money to revisit the RF-health controversy. For its part, the cell phone industry has long argued that it wants health research to come to an end.
