From my experience, they don't "Touch your privates"...at least not that I'm aware of, I would think that's illegal & against the rules...We should be grateful that the airports are taking extra measures to ck ppl out. You can NEVER tell who's a threat or not & they should never take anyone's word for it that they're okay & not out to cause any trouble. This is business, nothing personal... If you have an issue w/getting patted down, go thru the scanner. It's really not a big deal. If you have nothing to hide why should you worry? Is the whole world going to see the scan? Prob not. Other than the children, we're all adults here as are the security ppl & we ALLL know what a 'naked body' looks like. I've seen live action use of these scanners & it's not what you think...they show thru the clothes, yes but it's not a 'live photo', at least not the one's I've seen being proposed. It's like x-ray. Even if we now hafta be virtually scanned...so what if someone gets embarrassed, that's their problem. The security teams are only doing their jobs & I'm sure they hafta give a background ck before they're hired. These are not perverts getting joy out of patting ppl down to 'cop a feel' or sitting there laughing at someone who is overweight & they can see their fat rolls, they're professional adults like yourself, or at least they should be. I've been patted down before b/c I forgot & wore cargo shorts w/snaps & had to be patted down 'to make sure'. I am female & a female security person patted me down & was very professional & respectful. She didn't 'fondle my butt' or anything else so I'm not sure where you rec'd that info about "extensively feeling butts". They shouldn't "feel you up" at all, I know she didn't "feel ME up." she patted my pocket areas & since I was wearing shorts, she only felt on both sides of my thighs & not "up in the crotch", only up in the crease of where my thighs were, that "V" area; she slid her hand up against my bra under the boob area, on the ribcage area b/c I wear underwire & it sets the alarm off. Her hands did not cup on my boobs or under my clothes, she touched my bra hook area on back briefly as it was a 'target area' that set the hand scanner off b/c we all know, snaps are metal. This was all open palm too, I've never had them use the back of the hand, I've never even seen it done that way when I've traveled at least. It was quick & professional & only lasted a min or two but if you worried that someone will 'fondle' you or your children, ask a female to pat you down if you feel more secure that way or ride the bus or drive. Visit the airport in advance & ask to watch how they 'pat' everyone down but you've been aware of these security measures for quite some time so this shouldn't come as a surprise to you. Again, we should be grateful that the airports are taking extra measures to ck ppl out. We can NEVER tell who's a threat or not & they should never take anyone's word for it that they're okay & not out to cause any trouble. Ppl can be down right sneaky these days w/all the new technologies & everything that's going on in the world today, even using their children as pawns to carry in explosive material...I've read abt that. Regardless of what type of person you are, you're the same as everyone else, including your children. I may be quite obese and a modest person & have nothing to hide but my fat but I wouldn't think twice or hesitate about going thru the scanner or getting patted down. I'm the same as everyone else & should be treated as such & as far as the research you did on CT scans, you're not going to be in there for more than a min I think. I'm sure that yes, there are reprucussions of being exposed to that type of material but I think that has to do w/constant exposure over a long period of time...not 30 seconds to a min for a scan. I think you're getting mixed information & if I'm wrong, then I apologize but I have yet to experience anything but professionalism from the security teams at the many airports I've traveled thru. Best wishes on your trip though. Whatever you decide, I'm sure it'll be fine.
