That's not the point. Many unpleasant things have no health risks - that's no reason to have an enema after every meal or to wear a crash helmet in a taxi.
My objections are threefold. First, the US has been forcing allied countries to install these expensive nudeoscope scanners and run a no-scan, no-fly regime - something they don't themselves enforce.
Second, the nudity. Yeah, sure, they say there are all sorts of safety features, but at some stage the raw image is that of a person without their clothes. There's the potential for abuse.
Third, I've gotten my routine down to stacking my metal bits in a tray and walking through the detector. That suits me fine. I prefer not to pirouette and flap my arms.
I opt out of these things in the US. Sure, it means I get a pat-down, but I figure I'm inconveniencing the TSA folk just as much as they are inconveniencing me, and if enough people follow my example then they will have to think of something else.
As for Clive Palmer, let's just say that if I had his money, I wouldn't be spending it on the sort of things he is.
