Cellphone ‘Death Grip’ Increases Radiation Exposure Part 2
www.emfnews.org www.emfnews.org www.emfnews.org A 2009 study from the Environmental Working Group measured the radiation from more than 1200 mobile phone models. While the EWG study could not draw any conclusions as to the risks of mobile phone use, it did provide the beginnings of the group’s database of mobile phones and their emissions. Currently, the group ranks the Motorola Droid, iPhone 3GS, Google Nexus One, BlackBerry Bold 9700 and Samsung Instinct HD as the top five most radio-emissive phones. All of them, however, fall within the FCC’s acceptable SAR (specific absorption rate) limit of 1.6 watts per kilogram (1.6 W/kg). The Tawkon application gets all its information about the phone’s radiation from the cellular protocol stack that manages the baseband modem. “We use this information in the form of different RF parameters extracted from the device itself,” Lubovsky said. “We then take into consideration the proximity of the phone to the user –for example if the phone is held against the user’s ear or on the user’s lap– to help determine the actual exposure level at any given time.” “As part of the production procedure we have, each device goes through a long calibration process in an RF lab prior to its release to make sure that our measurements meet the actual values,” he continued. Tawkon is available only on the BlackBerry platform via App World, Mobihand and Handango, but not on Android or iOS as shown in the video. “It works on the iPhone, but we’re …
