Researchers from the National Toxicology Program exposed male rats to the type of radio frequencies which are commonly emitted by mobile phones. Following this exposure, “low incidences” of two types of tumours were found in the animals in both the brain and the heart. Tumours were not found in rats not exposed to the frequencies. More than 2,500 rats were experimented on at intervals over a two-year period.
In a report, the researchers said, “Given the widespread global usage of mobilecommunications among users of all ages, even a very small increase in the incidence of disease resulting from exposure to (radio-frequency radiation) could have broad implications for public health.” The study is thought to be one of the largest and most in-depth analyses of mobile phones and cancers. Ron Melnick, a former National Toxicology Program researcher who reviewed the results said, “Where people were saying there’s no risk, I think this ends that kind of statement.”
