An anonymous reader writes "A U.S. government report released on Tuesday says the Federal Communications Commission needs to update its guidelines for limiting cell phone radio-frequency exposure. The limit was set in 1996 to an exposure rate of 1.6 watts per kilogram, and has not been updated since. The report does not advocate in favor of any particular research, and actually points out that the limit could possibly be raised, but says the FCC's rules have not kept pace with recent studies on the subject one way or the other. An executive for The Wireless Association said, 'The FCC has been vigilant in its oversight in this area and has set safety standards to make sure that radio frequency fields from wireless phones remain at what it has determined are safe levels. The FCC's safety standards include a 50-fold safety factor and, as the FCC has noted, are the most conservative in the world.'"
