The newest TSA airport scanners may pose a cancer threat.

According to a growing number of scientists and doctors the newest TSA airport body scanners, known as Advanced Imaging Technology (AIT) scanners, may pose a cancer threat.*

The Transportation Security Administration (TSA) insists the scanners are safe, and cites independent studies saying the radiation levels are below acceptable limits. However, according to some doctors, even a small dose of the ionizing radiation that the machines emit could pose a danger.

The TSA has installed about 250 of these body scanners at 40 U.S. airports.

*In Wisconsin, to proceed beyond mere speculation as to causation, a competent physician would have to indicate that the workplace exposure for a substantial period of time to the radiation from airport scanning was at least a material, contributory, causative factor in the onset or progression of a worker’s cancer condition.
