Does the radiation emitted by cell phones cause brain cancers? Although most of the scientific evidence suggests that it doesn’t, the media always seems to find a physician or a patient or even a scientist who is willing to talk about it. The debate has been going on since cell phones first came out, and it’s not likely to go away any time soon.
Are you concerned? How much radiation does your cell phone emit, anyway – a lot, or a little? The Federal Trade Commission sets an upper limit of 1.6 W/kg (watts per kilogram) for certification, but commercial phones on the market vary all the way from 1.6 down to 0.14 – more than a 10-fold difference.
For a complete listing of the radiation output of all current phone models, go to http://reviews.cnet.com, go to “Cell phone reviews”, then click on “Cell phone radiation charts.”
