BlackBerry Bold Tops New Radiation Ranking
Data from the Environmental Working Group places the BlackBerry Bold 9700 as the mobile device with the highest legal levels of cell phone radiation among popular smartphones, followed by the Motorola Droid, LG Chocolate and Google's HTC Nexus One.Research In Motion's BlackBerry Bold 9700 scores the highest among popular smartphones for exposing users to the highest legal levels of cell phone radiation, according to the latest 2010 Environmental Working Group ranking. Following the Bold 9700 are the Motorola Droid, the LG Chocolate and Google's HTC Nexus One.
The rankings still put the phones well within federal guidelines and rules. The FCC's cell phone radiation standards closely follow the 1992 recommendations of the IEEE (Institute of Electrical and Electronics Engineers). These standards allow 20 times more radiation to penetrate the head than the rest of the body and do not account for risks to children.
FCC standards limit the radiation absorbed by a cell phone user's brain and body to a specific SAR (absorption rate), measured by the amount of the phone's radiation energy (in watts, W) absorbed per kilogram of tissue (W/kg).
