[ RadSafe ] Neutron Detection Instrument Recommendation

[Cueva, Louie]

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!
