Why Was I Thinking a Civil Defense Survey Meter Would Detect Alpha Particles?

 Gamma only.  That uranium ore is of no value.  Apparently the K40 in banana is gamma rays but I doubt that will get enough bunches to measure. 


Does anyone need it?

I guess that I will assume the calibration done in 2009 is sufficient or that sanity breaks out.

  1. CDV 700 will detect K40 in bananas.

    It is sensitive enough.

    The 715/717/720 are not sensitive enough.

    None will detect Alpha.

  2. I thought the CDV-700 probe had an openable window to allow alpha detection.....
