Ranking RIM BlackBerry RF Radiation Levels by SAR: How Does Your Smartphone Measure Up?

Whether or not cell phones can actually lead to or accelerate health problems remains unclear but we do know the trusty little devices emit radio frequency energy, and it's a fact that too much radiation's not a good thing for humans. That's why the Federal Communications Commission (FCC) analyzes and measures mobile device radiation-emission levels before giving them the thumbs up for sale in the United States. That metric is called a Specific Absorption Rate (SAR), and to pass the FCC inspection, a phone's SAR must be equal to or less than 1.6 watts per kilogram (W/kg).
