The Environmental Working Group (ewg.com ^[1]) analyzed the radiation emissions from 1,268 cellphones.

Apple’s iPhone 3G has a maximum SAR of 1.39 W/kg when held at the ear. You can compare that to the 1.19 W/kg SAR for the iPhone 3GS. The lower the SAR the safer the phone is. The best phone was the Samsung Impression which had a max radiation of just 0.35 W/kg.

“The FCC limit for the head (SAR of 1.6 W/kg) is just two-and-a-half times lower than the level that caused behavioral changes in animals (SAR of 4 W/kg),” says the representative. “Thus, the brain receives a high exposure, even though the brain may well be one of the most sensitive parts of human body … and should have more protection.”

Here is a list of EWG’s top 10 phones, based on low and high emissions:
