Cellphone radiation poses no real harm to humans, new research says
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.
