San Francisco’s Phone-Radiation Law Sparks Similar Proposals

A handful of U.S. cities may follow San Francisco’s example in trying to make information on mobile-phone radiation levels readily available to consumers, setting the stage for a broader showdown with the wireless industry.

San Francisco aims to become the first city in the country to require large wireless retailers to prominently display a device’s specific absorption rate, which measures how much energy emitted by a phone is absorbed by the body. The ordinance goes into effect on Feb. 1, unless it’s stopped in the courts.
