[ RadSafe ] Neutron Detection Instrument Recommendation

[JPreisig at aol.com]

Dear Radsafe:
 
     I like LiI(Eu) detectors for thermal  neutrons.  You can read about 
them in Patterson and 
Thomas's book Accelerator Health Physics, if you actually find a  copy.  
Also interesting is any
book of course notes on Accelerator Health Physics by Cossairt.
 
    Neutron Remballs, I believe, have BF3 detectors.   The detectors just 
can be pulled out of the
spherical moderator.  Don't know who makes the remballs.
 
    Ludlum has LiI(Eu) detectors for sale, and I expect you  could buy one 
or two such detectors without
a full set of Bonner Sphere moderators, which are pretty expensive.
 
    Good Luck...  Joe Preisig

I  received an atypical "Friday afternoon" question from a researcher and 
wanted  to share with the list.  His interest is in detecting ambient thermal 
 neutrons via boron interactions.  Essentially he's looking for a "bare"  
BF3 detection instrument without a polyethylene moderator.  Hoping to  garner 
ideas for commercial off the shelf products (or close to it) that might  
fit the bill?  Most results I found in quick internet searches of common  
radiation safety instrumentation providers yielded instruments that are either  
moderated or have moved to He-3 detector designs.

Any suggestions are  greatly appreciated!
