The European Union (EU) issued a rule banning X-ray body scanners in all European airports on the basis of jeopardizing citizen's health, a contradiction made a day after the European Commission adopted a propose to implement the scanners.

The EU enforces screening policies similar the U.S. Transportation Security Administration's (TSA) to 27 of the EU's member countries.

The ban comes in wake of the Commission's Nov. 14 confirmation of a proposal that outlines the security-scanning framework, which if implemented, would allow the region's airports that choose to use the scanners to do so under rigid and operational protocol.

Since 2009, following the so-called "Underwear Bomber," who attempted blow up an aircraft flying from Amsterdam to Detroit with plastic explosives hidden in his underwear, member states have been trailing and testing security scanners.

"Security scanners are not a panacea but they do offer a real possibility to reinforce passenger security," said Kiim Sallas, EU commissioner responsible for transport. "Security scanners are a valuable alternative to existing screening methods and are very efficient in detecting both metallic and non-metallic objects."

According to New York City-based ProPublica, a non-profit investigative news corporation, the Food and Drug Administration (FDA) raised safety questions in 1998 regarding the use of radiation. The agency said passengers should not be X-rayed other than on medical basis.

The final protocol to deploy some 250 X-ray machines in a post-9/11 world, along with 264 body scanners, which use low-energy radio waves rather than radiation, according to ProPublica, was not an FDA decision; however, the agency said Nov. 11 the risk of cancer caused by the scanners is generally low. The risk of fatal cancer, FDA says is one in 400 million.
