There is a growing amount of concern and unhappiness at the rush by the TSA to deploy whole body imaging scanners – they may or may not work and they may or may not subject passengers to dangerous doses of radiation.
The US Government Accountability Office accuses the TSA of deploying the machines without fully testing them and without assessing whether they can effectively detect concealed explosives. The Israelis condemn them as being useless, and a growing body of scientific evidence suggests that the radiation levels may be hundreds of times more harmful than the government claims them to

Probably nothing will stop the TSA from continuing full-speed ahead with their plans to waste hundreds of millions of dollars purchasing and deploying these machines at US airports. But there is one thing that we can all do and we should all do. If we are ever selected to go through one of these machines, just say no.
Fortunately, we currently have a right to refuse to be screened by one of these machines, in which case we will be given a pat down search instead. If everyone makes a point of always refusing to be subjected to these whole body imaging machines, perhaps sooner or later the TSA will get the message and turn them off permanently.
There is one more reason why we should always refuse to go through these machines. As long as sufficient people exercise this right, it will remain available to us, but if most people meekly comply, then those of us who do not want a bonus dose of radiation will be treated more suspiciously/aggressively by the TSA and our right to refuse may end up being removed based on a spurious claim that ‘no one complains about it anymore’.
