Phone radiation limits are different depending on where you live. The FCC/IC (USA Standard) and the Council of the European Union (EU Standard) are measured over a different amount of tissue, either 1g or 10 grams, and different maximum power levels of 1.6 W/kg vs. 2.0 W/kg, so they are not directly comparable.
