What it all means
According to the Cellular Telecommunications Industry Association (CTIA), SAR or specific absorption rate is "a way of measuring the quantity of radiofrequency (RF) energy that is absorbed by the body." For a phone to pass FCC certification, that phone's maximum SAR level must be less than 1.6W/kg (watts per kilogram). In Europe, the level is capped at 2W/kg. The SAR level listed in our chart represents the maximum SAR level with the phone next to the ear, a level obtained through required FCC tests.
It's important to note that in publishing this list are we in no way implying that cell phone use is or isn't harmful to your health. While research abounds and some tests have shown that cell phone radiofrequency (RF) could accelerate cancer in laboratory animals, the studies have not been replicated. Cell phones can affect internal pacemakers, but there is not conclusive or demonstrated evidence that they cause adverse health affects in humans. So in short, the jury is still out, research is ongoing, and we will continue to monitor its results.
If your phone isn't listed here (U.S. customers) and you've purchased it within the last few years (the FCC Web site currently does not provide information on models certified before 1998), you can request the SAR information from the manufacturer or your carrier. You'll need the model number and FCC ID number, which is usually but not always listed in your owner's manual or under your phone's battery (you must pop the battery out). We'll continue to update the list as new phones are announced. To be the first to know when we've added more phones, subscribe to the On Call Newsletter.
