I get that and I appreciate the additional info on radiation exposures (I had not seen the 2nd link you posted before).

I was trying to imply that the argument of "it's not that bad" can quickly become moot considering that imaging companies have more powerful scanners standing by for purchase & use. It really becomes a question of how much is too much? And, for what benefit am I being dosed with an extra amount of radiation?

Unfortunately, most travelers are unaware that they are even being dosed with radiation by a scanner. No doubt, the TSA would like to keep that fact hidden.
