Cell Phones' Radiation Report Card

The amount of radiation emitted by cell phones varies from model to model, but all fall under the FCC-mandated maximum absorption rate of 1.6 watts per kilogram of body tissue. Here's a look at some of the highest and lowest emitters

According to the nonprofit Environmental Working Group (EWG), this popular Blackberry is one of the worst phones in terms of radiation emission, with an absorption rate that comes close to the maximum allowed by the Federal Communications Commission.

As cell phones make and take calls, they emit low-level radio-frequency (RF) radiation. Stronger than FM-radio signals, cell phones' RF waves are still a billionth the intensity of known carcinogenic radiation like X-rays.
