Considering no one can figure out what kind of dose we're actually
getting I guess the next set of questions would be: 
Who is licensed to use and operate these machines? 
Do the operators possess a Limited X-Ray License or any form of
Just what are the licensure requirements?
Are the x-ray units registered and operated in compliance with the state
in which they are used. 
Who does the annual (?) safety inspections? 
Where are the manufacturer's specifications published?
For regulatory purposes how are these classified - medical, industrial,
Under what regulation is it permissible to drive around in a backscatter
van and randomly X-ray everyone and anything?

None of this is passing my giggle test.

The TSA will not let anyone wear a small dosimeter during a scan. Why

Does the TSA oppose objective measurements by independent experts of 
actual dose to the skin during a typical scan?
