How much radiation does your cell phone emit? It's easy to find out the answer thanks to the Environmental Working Group's new online guide to cell phone emissions. The non-profit research and advocacy group ranked over 1,000 different cell phones according to radiation levels. It looked at the publicly available, but difficult to find, specific absorption rate (SAR) for each phone. SAR is a measure of how much radiation is absorbed by the body when the phone is sending a signal to the network. (source: green.yahoo.com)
