In the wake of the attempted Christmas Day bombing, the Transportation Security Administration will increase screening for weapons using full body scans. And that has some travelers worried these scanners could increase cancer risk through radiation exposure. But experts at the American College of Radiology say this is unlikely.
In a statement, the organization notes that both types of scanners used by the TSA use low level rays that pose essentially no cancer risk . They claim the devices use such low level radio waves that DNA will not be damaged.
The group says travelers would need to have 2,500 scans to raise cancer risk by even a tiny amount.
