 The release of a study Friday linking cancer in rats to the type of radiation emitted by cell phones presents some of the strongest implications in more than two decades of research that higher doses of such signals could be linked to tumors in laboratory animals—unsettling news for billions of mobile phone users worldwide. Still missing, however, is a clear understanding of exactly how radiofrequency (RF) radiation used by mobile phones might create cellular-level changes that could lead to cancer.
The study by the U.S. National Toxicology Program (NTP) found that as the thousands of rats studied were exposed to greater intensities of RF radiation, more of them developed rare forms of brain and heart cancer that could not be easily explained away, exhibiting a direct dose-response relationship. NTP acknowledges that the research is not definitive and that more research needs to be done.
(...) Cell phone radiation is non-ionizing radiation. X-rays, for example, are ionizing radiation and contain sufficient energy to break chemical bonds. Non-ionizing radiation associated with radiofrequency fields is very, very low-energy, so there’s insufficient energy to break chemical bonds. It was always assumed that because the power being created by the handsets was low enough, there would be insufficient energy for heat production—and without heat production there would be no biological effects [on users] whatsoever.
