UPDATE 3
A new group of IARC advisors is meeting in Lyon this week to set priority agents for the agency to review in 2025-2029. More here.

January 19, 2024
UPDATE 2
IARC has announced that the agency will evaluate the cancer risks of “automotive gasoline and some oxygenated additives” from February 25 to March 4, 2025. The reassesssment of RF radiation will have to wait.

October 25, 2023
UPDATE 1
Other Monograph meetings have now been scheduled for March, June and November 2024. The next possible slot for RF radiation is in early 2025.

December 12, 2022

On November 23, 2002, Elisabete Weiderpass, the Director of the International Agency for Research on Cancer (IARC), revealed that a new assessment of the evidence linking radiofrequency (RF) radiation to cancer would likely take place in early 2024. A formal decision could come within a few months.

Calls for a new IARC evaluation have been mounting for some years following the release of two large animal studies showing elevated tumor counts after lifelong exposure to RF radiation.

The Japanese group running a partial repeat of the NTP RF cancer study has not observed genotoxic effects among male rats exposed to 900 MHz CDMA radiation at 4 W/Kg, according to a paper to be presented tomorrow at the annual meeting of the Society of Toxicology in Salt Lake City, UT (SOT2024).

The analysis of the cancer data is ongoing and will not be reported.

A Korean RF genotoxicology study —part of a joint project with Japan— has been delayed due to the unexpected death of four of the RF–exposed rats early in the accompanying two-year cancer experiment, according to Young Hwan Ahn of Ajou University medical school.

Ahn presented a progress report on the Korean arm of the project in Geneva last week at a meeting of the WHO EMF Project’s International Advisory Committee. Microwave News has obtained a copy of Ahn’s PowerPoint presentation.

“Cellular Autofluorescence Is Magnetic Field Sensitive,” PNAS, January 19, 2021. A big step forward for the radical pair mechanism to explain biological interactions with magnetic fields.

November 23, 2020

An international briefing on RF health research, known as GLORE 2020, was held online, November 9-12, featuring updates on the second phase of the U.S. National Toxicology Program (NTP) project and the Japanese-Korean partial repeat. The WHO presented a status report on ten ongoing systematic reviews of RF health effects.

Government and industry representatives from Australia, Canada, France, Japan, Korea, New Zealand and the U.S. participated, as did an assortment of academics. The public was not invited.

Everything about GLORE 2020 is being kept secret.

The Japanese Ministry of Internal Affairs and Communications is circulating a report on the partial replication of the U.S. National Toxicology Program’s RF–animal study, planned by Korean and Japanese officials. It includes the proposed candidates for the project’s International Steering Committee. 

They are:
• Alexander Lerchl, Jacobs University, Germany
• ...

Japanese and Korean officials are working on a partial replication of the U.S. National Toxicology Program (NTP) animal study on cancer risks from cell phone radiation. The project is expected to be approved and get underway late next year.

Though collaborating on a common experimental design, each country will carry out its own exposures with animals from the same breeder. If the designs are similar enough, the two sets of data will be combined in a joint analysis.

“We have been discussing this issue in Japan,” said Masao Taki of the Department of Electrical and Electronic Engineering at Tokyo Metropolitan University, who was a member of ICNIRP from 1996 to 2008.

Some news notes on the Interphone study:

• Those who say there are no long-term cell phone risks often point to the Interphone study from Japan, published earlier this year, for support. As we have previously reported, the Japanese researchers said there was no association between cell phones and brain tumors, even though they found a close to sixfold increase in glioma among heavily-exposed users after ten or more years (see our February 15 post). That link was based on a small number of cases and was not statistically significant; the Japanese attributed the increase to recall bias. Bruce Hocking, an occupational and environmental health physician in Melbourne, Australia, suggests otherwise. In a letter published this week in the British Journal of Cancer, Hocking points out that the risk of meningioma (another type of brain tumor) is hardly raised at all (OR=1.14). He writes: "If recall bias is the true explanation for the increased risk of glioma, it should similarly have affected the meningioma group, but it has not. Therefore, the increased risk in the glioma group may be a true finding."

If anyone is still not convinced that the completed Interphone study should be released as soon as possible (see our January 30 post), they need look no further than how the Interphone results from Japan were handled last week.

Japanese researchers do not see an increase in acoustic neuroma among users of mobile phones. In a paper appearing in the December issue of Occupational and Environmental Medicine, a team led by Naohito Yamaguchi of the Tokyo Women's Medical University reports that the "risk of acoustic neuroma did not increase with the duration of mobile phone use, nor with the total call time."

Magnetic fields have been linked to childhood cancer in many countries and now it's also been shown in Japan. Michinori Kabuto, of the National Institute of Environmental Studies in Ibaraki, along with a number of collaborators have found that children exposed to 4 mG (0.4 µT) or more in their bedrooms had close to five times more leukemia than those living in low-exposure homes. This statistically significant finding appears in the August 1st issue of the International Journal of Cancer.
