San Francisco to regulate cell phone emissions

San Francisco Chronicle : San Francisco’s city council—its Board of Supervisors—voted on Tuesday to approve a new regulation that governs the sale of cell phones. If city mayor Gavin Newsom signs the law, shops that sell cell phones will have to disclose how many watts per kilogram of body tissue each type of phone emits. The Federal Communications Commission limits that emission measure, known as the specific absorption rate (SAR), to 1.6 W/kg, but does not require device manufacturers to disclose SAR values to customers.
