The FCC’s 1.6 watt per kilogram level for damage to tissue is set up as a threshold, meaning that any levels below it, whether 0.1 or 1.5, are supposed to be equivalently safe.
Accordingly, groups that represent cell phone makers say that pitting one phone against another safety-wise based on SAR is a false choice.
“Rather than inform, the ordinance will potentially mislead consumers with point of sale requirements suggesting that some phones are ‘safer’ than others based on radiofrequency emissions,” said John Walls, vice president of public affairs for the Cellular Telecommunications and Internet Association, in a statement.
Generally, no manufacturer or particular kind of cell phone tends to produce more radiation than competitors or other devices, Naidenko said.
In other words, an advanced, features-laden smartphone such as the Apple iPhone can (and does) emit fewer radio waves than a basic budget cell phone, like a Nokia Surge. (The SAR level of the iPhone 3GS is 0.24 to 1.03 watts per kilogram and the Surge’s is 1.31 watts per kilogram. The iPhone 4 SAR is not yet publicly available.)
