Male rats showed a small increase in a type of heart tumor after exposure to massive amounts of cellphone radiation, a new government study reports. But don’t read too much into that, experts say — because those radiation exposures were much bigger than even the heaviest cellphone users would experience.
Male rats showed a small increase in a kind of heart tumor after exposure to massive amounts of cellphone radiation, a new government study reports. But don’t read too much into that, experts say — because those rats bathed in more radiation than even the heaviest cellphone users would experience. There are ongoing worries about whether cellphones can give you cancer — especially brain cancer, since our phones spend so much time near our faces. It’s true that cell phones do emit radiation.
Based on the NTP’s results, as well as hundreds of other studies, the FDA is still confident that the current limits on cellphone radiation are safe, according to a statement from Jeffrey Shuren, the director of the FDA’s Center for Devices and Radiological Health. The study specifically used 2G and 3G frequencies — not the frequencies used on more advanced 4G or 5G networks. Researchers exposed the rodents’ entire bodies to the radiowaves for more than nine hours per day, for up to two years.
