      Don't know if this really exists, but I've heard of something like
it.  A suitcase is placed next to the suitcase
to be screened.  A neutron generator produces neutrons and a
photomultiplier tube or other detector detects
the return gammas or whatever.  Shhhhhh....

> Description
> Passenger screening at commercial airports in the United States has gone
> through significant changes since the events of September 11, 2001. In
> response to increased concern over terrorist attacks on aircrafts, the
> Transportation Security Administration (TSA) has deployed security systems
> of advanced imaging technology (AIT) to screen passengers at airports. To
> date (December 2014), TSA has deployed AITs in U.S. airports of two
> different technologies that use different types of radiation to detect
> threats: millimeter wave and X-ray backscatter AIT systems. X-ray
> backscatter AITs were deployed in U.S. airports in 2008 and subsequently
> removed from all airports by June 2013 due to privacy concerns. TSA is
> looking to deploy a second-generation X-ray backscatter AIT equipped with
> privacy software to eliminate production of an image of the person being
> screened in order to alleviate these concerns.
