[ RadSafe ] Fwd: Neutron Generator regulations

[JPreisig at aol.com]

Mike,
 
      This all makes me wonder if  Radiation/security people even have 
neutron detectors.  Sure, XRays would  work in such a scenario also.

While such a thing would almost certainly get some excited  news coverage
when discovered, I suspect it would be difficult to do much  harm with
it.  You could accomplish as much by doing the same thing  with an x-ray
tube, which would be cheaper and easier.  

As for  directing the neutron flux, I haven't been paying attention to
that field,  but the last time I looked it was more a matter of shielding
in all but one  direction, with the neutrons going the wrong way  being
absorbed.

Radsafe:

Something to  consider about neutron  generators.  If a person is
well-trained  in electronics, and perhaps they  could get their hands on
a neutron  generator, then they might possibly be able  to build a
suitcase  version of a neutron generator weapon.  Take the  suitcase to
the  location of 
interest, plug it in and turn it on from afar.    Kind of like a poor
man's neutron 
bomb.  Quite lethal if  done  correctly.  It wouldn't explode, but rather
would just  provide a neutron  flux density (directed???) and would kill
people  and/or other animals.
I guess security people should be taught to keep an  eye out for
suitcases and/or other packages which are plugged in to an  electrical
socket.  When one would see such a suitcase or whatever,  then one should
move away from the  suitcase.  Safety teams could  approach such a device
with a remball, Snoopy, Anderson-Braun detector etc.  to see if a neutron
signal is  present.  
The next step to do  would probably be to turn-off local electric  power,
and again  approach the suitcase with some caution.  I don't know if  any
of  this scenario is likely.  From what I can remember, Schlumberger
keeps  track of it neutron generators.

What are  the regulations regarding an electronic neutron  generator?  
Something  like a D-D fusion type.  It's  possible to make one in a
reasonably well  equipped lab, so if someone  did, what licensing and use
regulations would  apply?
Regulations  on an x-ray machine are fairly clear (and they're   MUCH
more  
common! - both the machines, and regs!).
I realize that "standard   radiation dose limits" would apply, but most
of the regulations I see  are  associated with the Tritium content of a
D-T generator, is there  anything  special someone would have to do if
they made a D-D  neutron  generator?

And yes, I realize that if it was done in a  DOE facility  their rules
would apply.

Thanks in  advance!
