[ RadSafe ] HPGe efficiency calibration source for soil samples

[JPreisig at aol.com]

Hey Radsafe,
 
      I did use a Personal Computer based MCA  system called the Inspector. 
 It worked pretty well.
I don't know about low cost, though.  Physics Today sometimes has  
advertisements concerning
Multi Channel Analyzers.  Good Luck.

Mr.  Willis, did you get an answer to your Tokyo soil sample analysis  
question?

The reason I ask is that I also want to play with mca's  again as a hobby 
myself.  It has been many years since I did that  professionally and I'd 
like to take it up again.  So far, I have no  equipment, no sources, and 
no samples.  :) :)  I hear all these  tales of low cost equipment but I 
can't find any via web  searches!

Thanks,
David  Merchant
