San Francisco backs posting of cell phone emission levels

San Francisco moved a step closer Tuesday to becoming the first city in the nation to require that retailers post in their stores notices on the level of radiation emitted by the cell phones they offer. The Board of Supervisors voted 10-1 to give preliminary approval to the proposal. Final approval is expected next week. Supervisor Sean Elsbernd was the lone vote in opposition. Mayor Gavin Newsom, an early proponent of the legislation, plans to sign it into law when it reaches his desk. Cast by backers as a pro-consumer measure, the ordinance would not ban the sale of certain cell phones but would require retailers to provide the "specific absorption rate" - a measurement of radiation registered with the Federal Communications Commission - next to phones displayed in their shops. Consumers also would be notified about where they can get more educational materials.
