Apple's latest iPhone, the 3GS, ranks almost squarely in the middle of smartphones in terms of radiation output, a non-profit activist organization says. The Environmental Working Group notes that according to compiled data, the 3GS produces approximately 1.19W/kg of radiation. The figure is substantially lower than the worst-case examples, the T-Mobile myTouch 3G and the Kyocera Jax S1300, which each produce 1.55W/kg.
