Meanwhile, Europe BANS the use of X-ray scanners for non-medical reasons:
The European Union on Monday prohibited the use of X-ray body scanners in European airports, parting ways with the U.S. Transportation Security Administration, which has deployed hundreds of the scanners as a way to screen millions of airline passengers for explosives hidden under clothing.
The European Commission, which enforces common policies of the EU's 27 member countries, adopted the rule “in order not to risk jeopardizing citizens’ health and safety.”
As a ProPublica/PBS NewsHour investigation detailed earlier this month, X-ray body scanners use ionizing radiation, a form of energy that has been shown to damage DNA and cause cancer.-Europe Bans X-Ray Body Scanners Used at U.S. Airports
