Is your cellphone bad for your health? India's government seems to think so, because it's planning a law that will require all phones to display how much electro-magnetic radiation they generate. Radiation is measured in SAR (Specific Absorption Rate) and the Indian limit has been lowered to match the USA's 1.6W/kg, whereas before it followed the European ceiling of 2W/kg. But even handsets that meet this criterion may have to declare their SAR level, and also carry a message asking people to keep their calls or short or use SMS instead -- implying that the Indian government regards radiation as dangerous at any level.
