[ RadSafe ] Neutron Source Licensing Requirements

Zaid:

Nice to see you here in RadSafe.  It is not difficult to write the license 
application, just mind numbing with respect to the hoops they will make you 
jump through.

I believe Ohio is an agreement state, so contact the regulators there and 
ask for the forms you will need.  Also ask for any guidance documents or 
instructions they may have available.

An old trick is to do a FOIA request (or whatever the equivalent state open 
records law is called there in Ohio) for an exemplary permit application 
done by some other licensee (I used to actually say in the request that I 
wanted the one or two they considered the best they ever received) and use 
that as a template.  Back before computers, that is how lawyers built their 
"form files", the forms they copied when doing documents for clients.  The 
only hitch here is that your request may be denied on a homeland security 
rationale; it just depends on how much they have calmed down recently.

Your real problem is acquiring an AmBe neutron source.  There is presently a 
critical shortage of Americium-241.  There are a couple of members here on 
the list who can better address that situation if they are watching.

Good luck.
