The radiation worries me, but not the pat downs. My son has a pacemaker, so he is patted down every time we fly. They always, always, always use a same-sex patter. I've even suggested that I wouldn't mind if a woman did it, and they said no, we had to wait for a man. The same would apply to female travelers--only female agents can pat them down.

The radiation on the other hand... My son has been exposed to way more radiation than I'm comfortable with already, frequently without the little lead apron for his private parts (they're a little lax on that sort of safety measure here). No more of that than absolutely medically necessary, thank you very much.
