With the San Francisco Board of Supervisors voting 10-1 in favor of a new law related to cell phone radiation, mobile handset makers will have to reveal information about the “specific absorption rate” (SAR) – that is, the amount of radiation absorbed by the users of various mobile devices – in their products.
The law, which was tentatively approved by San Francisco on Wednesday, will essentially make it obligatory for the cell phone vendors to disclose the amount of radiation emitted by their phones.
According to a San Francisco Chronicle report, the implementation of the law – which will likely take effect in February 2011 – will make the city the first US city to have such a cell-phone-radiation-related measure in place.
At present, owners desirous of knowing the SAR details of their specific handsets can find all information on the Federal Communications Commission Website. To serve as a guideline in terms of radiation emitted, the maximum SAR level for any cell phone sold in the country is 1.6 watts per kilogram.
Meanwhile, a number of scientific studies and media outlets have, in recent years, cautioned cell phone users about an increased risk for cancer, especially in the brain.
However, the FCC Website states that though several studies are being conducted to ascertain the cancer risk, “there is no scientific evidence to date that proves that wireless phone usage can lead to cancer or a variety of other health effects.”
