According to the FCC documents, the iPhone puts out a relatively low amount of radiation compared to other phones. It is in the range of 0.3 to 0.6 W/kg in most of their measurements. As a comparison, my Motorola SLVR is something like 1.2 W/kg. The FCC allows a maximum of 2.0 W/kg. I'm always curious to know how much radiation my phone is putting out. Anyway... this is good news.
