My only experience (that I know of) with PIN diodes was a "personal radiation safety detector" Bill Fain bought for us to test. It had a supposedly large-area pin diode between two pieces of copper tape (keep the light out) and a preamp and amp to click when radiation hit, clamed also to be sensitive to neutrons.
Well, in some sense, probabably. They were so numb it was hard to get 60 cpm with on laying on top of my fusor - eg enough to completely saturate a geiger counter or 3He tube. Even tobernite - waste from a natural reactor in Africa that makes even a pen type electrostatic dosimeter read, was "nothing" to one of those. So, we sent it back.
Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
