<p>Every medical device has to be cleared by the FDA before it can be sold/used on humans. I have searched the FDA website and have yet to find a single study of the scanners' safety. Now a group of MDs questions the scanners' safety:</p>
A group of doctors and professors from UC San Francisco are raising new concerns about the safety of a type of airport full-body scanner built by Torrance, Calif.-based Rapiscan Inc.</p>
<p>To reveal weapons hidden under a traveler's clothes, the scanner relies on "backscatter technology," which uses the ricochets from low-level X-rays to create what looks like a nude image of the person.</p>
<p>The experts said they fear that the scanners may expose the skin to high doses of X-rays that could increase the risk of cancer and other health problems, particularly among people with weak immune systems.</p>
<p>But officials at the Department of Homeland Security say there is no need to worry.</p>
<p>"The risk is so low it's almost negligible," said Dr. Alexander Garza, the assistant secretary for health affairs and chief medical officer for the department.
<p>Hmmm... Who will you trust?</p>
