A new study by the Environmental Working Group has found that some cell phones emit more radiation than others.
In an exhaustive study, the agency examined and ranked more than 1,000 cell phone based on how much radiation they emit. They found that the Samsung Impression has the lowest emissions at 0.35 watts per kilogram. That's a measure of how much radiation is absorbed into the brain when the phone is held near the ear.
The tested phones with the highest watts per kilogram ratio were the T-Mobile MyTouch 3G, the Motorola Moto VU204 and the Kyocera Jax S1300. All came in at 1.55 Watts per kilogram.
Under guidelines set by the Federal Communications Commission, which sets the standards for cellphone radiation, all wireless devices must be rated at 1.6 watts per kilogram or lower. However the Environmental Working Group says that rating was set 17 years ago is outdated because cell phones and wireless usage patterns have changed so much. They're asking the government to take a "fresh look" at radiation standards.
Cell phone radiation has become a hot topic in the past few years. A number of watch dog groups say that it is possible that cell phone radiation could cause cancer. They also say a number of recent studies showing increased risk for brain and mouth tumors for people who have used cell phones for at least 10 years.
However, other groups say there is no hard link between cell phones and cancer. The American Cancer Society, World Health Organization and the Food and Drug Administration have all said that wireless devices do not pose a public health risk.
