Radiation in your cell phone

Last week, the San Francisco Board of Supervisors voted to move forward with a law (which is expected to gain final approval this week) that would require all cell-phone retailers in the city to post numbers showing the level of radiation emitted by each phone. While studies on the long-term effects of exposure to cell-phone radiation are inconclusive so far, the FCC does require that consumer cell phones sold in the U.S. have an SAR (specific absorption rate) of 1.6 watts/per kilogram or less. If you want to know how your phone’s SAR numbers stack up, check out CNET.com’s best/worst lists below and compare. (Your phone’s SAR number should be in your user manual. If not, look up your model at FCC.gov.)
