Effects of Using Bluetooth Headsets - Makes Pain of Ears & radiates too much Heat
Both wireless phones and Bluetooth devices emit nonionizing radiation, typically
at frequencies from 1 to 2.5 gigahertz. The data on health hazards from wireless
phone radiation are equivocal, with some studies showing a measure of risk and
some showing no problems.
INSIGNIFICANT BY COMPARISON." In the real world, emissions generally stay well below the maximum allowed. According to data from BlackBerry-maker Research in Motion (RIMM ), SARs for GSM BlackBerry devices (those sold by Cingular and T-Mobile in the U.S.) fall in the range of 0.25 watts per kilogram when used at your ear.
Bluetooth radios operate at much lower power levels than phones so, not surprisingly, the radiation added by a Bluetooth headset is insignificant by comparison. A study by William G. Scanlon of Queen's University in Belfast found that a typical Ericsson (ERICY ) Bluetooth radio module generates an SAR of just 0.001 watts per kilogram.
So, if you're worried about the health impact of radio waves, remember that the phone itself is a much greater source of concern than a Bluetooth headset. That's especially true because, when you're using Bluetooth, the BlackBerry is likely positioned much farther from your body -- and especially your brain -- than when holding the phone up to your ear
