All very good questions. The answer is that NOBODY licenses, or registers
the units themselves or the users of these scanners. The regulation of
the use of x-rays is ordinarily the responsibility of the states. FDA
regulates the manufacturers of the equipment but the installation and use
of all such equipment is under state authority. The problem is that TSA
is a federal agency. As such it is immune from regulation by the states.
Another federal agency could regulate TSA, but no federal agency has been
given authority to do so. In effect TSA is self-regulated when it comes
to the application of radiation to humans. But, don't worry. They are
only trying to protect us.
