Airport full-body X-ray scanners banned across Europe as unsafe
Keep in mind that there are 2 types of machines in common use. 1) Backscatter (X-Ray) and 2) Millimeter Wave (Radio) and they operate very differently.Based on what I've read I'm comfortable with the millimeter wave system and have some concerns about the backscatter x-ray system. However, if the backscatter system operates correctly then the amount of radiation exposure is really quite small compared to the amount you'd receive on the actual flight. I still think I'd opt-out of the backscatter system until long term effects and performance are studied.Tip: Millimeter wave looks like a circular telephone booth, Backscatter x-ray looks like a big rectangular wall you stand in front of.http://www.jaunted.com/story/2010/1/5/163631/3181/travel/Ful...
