Does texting emit as much radiation as talking?
Cell phones use less power and emit less radiation to send text than voice signals. And unlike when you speak with the phone at your ear, texting keeps radiation away from your head. Back to Top 21. A question about SAR: (Specific Absorption Rate) values, which the Federal Communications Commission defines [http://www.fcc.gov/cgb/sar/ ] as the “measure of the amount of radio frequency energy absorbed by the body when using a mobile phone.” Some phones in your database have just one SAR value, “SAR when held at the ear”, while others also have other SAR values, for example, “SAR when worn on the body.” For some models, the SAR value for the body can be even higher than that for the head. Why? For nearly three-quarters of the devices in the EWG database, the SAR value at the ear is higher than at the body. But for the remaining fourth, manufacturers’ tests show the body absorbs more radiation than the head. A phone’s SAR value is determined primarily by its design and antenna.
