It's been a topic of many discussions since cell phones practically became an appendage on most people: Do cell phones emit dangerous radiation waves?
Now, it looks like shoppers in San Francisco could have a key element in the equation to answer that question. The San Francisco Board of Supervisors on Tuesday voted 10-1 to give preliminary approval to a proposal that would require retailers to post the notices about the level of radiation emitted by the cell phones sold at their stores.
The ordinance, believed to be the first of its kind of law in the nation, would not ban the sale of any cell phones but it would make posting the information mandatory.
But some say the numbers will lead to confusion because there is so much debate, even among experts, about whether cell phones can be harmful.
The supes are expected to give final approval sometime next week. Gavin Newsom plans to sign the proposal into law when it reaches his desk. It would be phased in starting February.
