If you're handing these out to screeners who claim that the x-ray body scanners (the ones with two rectangular boxes) are only using radio waves, more power to you. If on the other hand, screeners are telling you that the MMW body scanners (the round booths) are using radio waves, well, the goobers are right. Note that, despite the sensationalist titles of some of the media reporting, the EU has not banned "body scanners". On the contrary, the EU has issued a ruling to ALLOW the use of body scanners, but only the MMW (radio wave) variety, and allow passengers to opt out. For countries like the UK which are using x-ray scanners without opt outs, this represents a limitation. For airports like AMS which are using MMW with ATR (and opt outs? I'm not sure), the ruling represents business-as-usual. For the majority of EU countries which have not yet installed body scanners, the ruling opens the door for them to do so. It's better than nothing but this ruling is hardly an unmitigated victory for the opponents of body scanners.
