What about those full body scanners? I always opt out due to health concerns. Does anyone known anything about the actual radiation levels involved in those and

  If you assume the dose is absorbed by the "whole body," then it isnt of any concern. However, in reality the energy is so low that almost all the dose is absorbed by the outer portions of skin, which could be more hazardous. Public-facing literature i've come across doesnt address this, so erring on the side of caution isnt a bad idea. More importantly it disincentivises use of these devices for security theater.

  I know a lot about them; I researched them extensively even to the point of talking to designers. I came to the understanding that they're quite harmless; even considering the radiation doses you get while flying after (because, radiation is additive of course)- However using them many times per day can cause damage to the skin over long periods of time. Regardless, Opt out anyway; if people choose to opt out the economics of the devices will stop making sense and perhaps they'll be a little less invasive in future. I will always opt-out, even when I'm being threatened or condescended to (as was the case in Gatwick airport some time ago).
