A 2009 study from the Environmental Working Group measured
the radiation from more than 1,200 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.
urrently, 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 waiting for Apple
approval to make it publicly available,” Lubovsky said.
“Android is expected to launch very soon.”
