Forget the embarrassment of your private parts being seen by strangers. The scanners can cause cancer—and TSA is trying to keep you from knowing about it.
The Transportation Security Administration (TSA) uses two types of body scanners. The backscatter machines are of particular concern because these X-ray scanners emit low levels of radiation and can cause cancer. The European Union has even put a moratorium on the scanners in light of the cancer threats—member states have been told not to install scanners until scientific assessment of risks has been carried out, and they will be banned completely in April if experts find them dangerous—but the US has so far swept the safety issues under the carpet.
