Researchers have been divided over the effects of cellphone radiation on human beings. While some studies suggest a link between long-term (10 years or more) cellphone use and cancer, many maintain that there is not conclusive or demonstrated evidence that cell phones cause adverse health effects in humans.

The Times of India writes in its Article “US-based Environmental Working Group (EWG) is among the organisations who believe that there is compelling evidence to prove the link between cancer and cellphone radiation. The group recently came out with five safest and five worst mobile phones in terms of cellphone radiation. The study is based on SAR or Specific Absorption Rate. SAR according to the Cellular Telecommunications Industry Association is “a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body.” For a mobile phone to get FCC certification in the United States, the maximum SAR level must be less than 1.6 watts per kilogram. In Europe, the level is capped at 2 watts per kilogram while Canada allows a maximum of 1.6 watts per kilogram. “
