Two major reports issued Friday by federal scientists found that there was some evidence the type of radiation released from cellphones can cause certain forms of cancer in male rats, but the reports — which include many inconclusive findings — are not likely to quell the debate over whether cellphone radiation poses a threat to human health.
Researchers at the National Toxicology Program found that there was “some evidence of carcinogenic activity” from cellphone radiation in male rats. About 6 percent of the rats exposed to the highest level of radiation studied developed schwannomas in their hearts, whereas there was no evidence of schwannomas in a group of rats that were not exposed to radiation, according to John Bucher, a senior scientist at the NTP.
The schwannoma example was the most compelling evidence in the studies that the radiation might be a carcinogen, Bucher said.
