As the Internet lights up with images of the iPhone 6 plus emerging from people's pockets bent like a used paperclip, it may be useful to consider this: Apple explicitly tells you not to carry your phone in your pocket, due to the radiation exposure threat it poses. In the little handbook that comes with every iPhone ... Apple also explicitly states that the phone is not supposed to touch your body much, if at all. The iPhone 3G safety manual warns that radiation exposure may exceed government standards during body-worn operation" if the phone is "positioned less than 15 millimeters (5/8 inch) from the body (e.g., when carrying iPhone in your pocket)." The iPhone, Apple says, should always be worn in a belt clip or holster. Cell phone radiation, measured in radio-frequency exposure, is regulated in the U.S. by the Federal Communications Commission (FCC). All phones must be tested to ensure that they emit a specific absorption rate of not more than 1.6 watts of radio-frequency energy per kilogram of body tissue, a rule designed to prevent harm from the heat generated by radio-frequency waves. There are ... gaps in cell phone radiation testing. The American Academy of Pediatrics, for example, recently urged the FCC to begin taking child users of cellphones into account. Radiation from cell phones is not an Apple-only problem, of course. Blackberry's user manual advises .59 inches of separation between the body and the phone. Earlier manuals pushed for nearly a full inch (.98 inch) of separation.
