Neutron PICs

[Johannes Strydom <js165@prism.gatech.edu>]

	I have some neutron PICs (Pocket Ionization Chambers) that were made by
Dosimeter Corporation.  I understand that this company has gone out of
business.  I am trying to find some documentation of how these things
work.  There are two different kinds:

	One is a fast neutron and gamma tissue equivalent dosimeter
		Model Number 884

	THe other is a thermal neutron dosimeter (Model # 609)

	If anyone has any information on these PICs, please let me know. 
Thank you.
