RF animal studies: Microwave News Article Archive (2004 - )

Much of the press coverage of the final NTP cell phone/cancer report was lousy. This time, the NTP seems to have wanted it that way.

Reporters were given very little notice to join the NTP teleconference on the release of the report. Nor was there much time to prepare a story for publication.

I received an email at 10:45 am on October 31 for a teleconference at 2 pm that same day. Many reporters missed the advisory and the call. Editors had little time to assign the story.

Attendance on the teleconference was spotty.

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.

Partial results of the Ramazzini Institute’s RF–animal study, which show a statistically significant increase in tumors in the hearts of male rats exposed to GSM radiation, were officially released today. They appear in Environmental Research, a peer-reviewed journal.

As we reported last month, the Ramazzini finding of Schwann cell tumors —called schwannomas— in the rat hearts is consistent with a similar finding by the U.S. National Toxicology Program (NTP) in a $25 million RF project.

In an interview with Microwave News, Fiorella Belpoggi, the senior author of the new paper and the director of the Ramazzini Institute’s Research Center in Bologna, Italy, offered her views on the new results, the parallels with those of the NTP and the implications for IARC’s designation of the cancer risk of RF radiation.

The National Toxicology Program (NTP) has changed course and will not —at least for the time being— publish its findings of increased DNA breaks among rats exposed to cell phone radiation as a stand-alone paper.

The DNA study, which is part of NTP’s landmark experiment showing that RF radiation can lead to tumors in the brains and hearts of laboratory animals, will now be incorporated in NTP’s Technical Report on the $25 million project, the NTP has told Microwave News.

In May, the U.S. National Toxicology Program (NTP) announced that male rats exposed to cell phone radiation developed higher rates of cancer. Soon, the NTP will explain how that might have happened.

The same RF/microwave radiation that led male rats to develop brain tumors also caused DNA breaks in their brains. Female rats —which did not have significant elevated tumor counts— had fewer DNA breaks.

All these findings are part of the same $25 million NTP project.

The NTP results provide “strong evidence for the genotoxicity of cell phone radiation,” Ron Melnick told Microwave News.
