Frankly, if you’re purposefully slowing down the line even though you travel once or twice a year and yet are frightened of the radiation or worried someone might “touch your junk”, I’m going to be annoyed at you and not TSA.
This was a reasonable post on the whole affair and probably the closest proximity to my undigested thoughts on it at this time.
UPDATE: Glen Reynolds makes sense too. I don’t fly enough to have a huge opinion here, but maybe a “frequent flyer” type of ID might be helpful too.

I have been all in favor of a Frequent Flier deal where you would have already had a background check, etc…but I suppose that pass/paperwork could be forged by the one that wants to blow stuff up. Sigh.
