SAN FRANCISCO - A new study shows going through full body airport scanners does not pose a significant radiation risk.
Researchers at the University of California estimated the potential risks for frequent travelers.
They found for 750 million flights taken by 100 million passengers, six cancers could be linked to airport scanners.
They add radiation risks from flying are higher and that a passenger would have to go through the scanner 50 times to match the radiation exposure of one dental x-ray.
There are nearly 500 body scanners in airports now. TSA plans to roll out another thousand by the end of the year.
