The reason that Paquette and I are making a big deal about the radiation of the scanner isn't because it is huge risk, it is because the threat of terrorist is really small. Less than 25 people/per year over the last decade including 9/11.
Yup, and we're looking a radiation exposure levels from the Rapiscan 1000 and similar devices leading to 8 deaths from cancer per year using the TSA numbers, and a bit over 100 per year using the SFSU numbers.
I suspect that the most effective real changes post 9/11 were the changes to a locked and armored cockpit door, and increased passenger awareness (e.g., a hijacking is no longer an inconvenient detour, but something a passenger might want to act on. AKA "Let's roll!", or "Excuse me, steward, but this gentleman seems to be tying to light his shoelaces on fire.")
