[ RadSafe ] Neutron Generator regulations

[Brennan, Mike (DOH)]

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!
