Re: Soil Scanning for Cs-137

Dave:

If you specifically want to detect Cs137 and rule out other nuclides, there
are several approaches.   A portable GeLi detector is one approach
(Canberra or EG&G ??).   There are several mfg's that make portable MCA's
with NaI detectors (I'm familiar with Oxford - but there are others).  
There is also a nice compact unit made by Exploranium (GR-130) that
incorporates a NaI detector, a count per second mode, a uR/hr mode and an
MCA mode, all in one instrument.   It should have enough counts to identify
Cs137 if you are in the 50 - 100 pCi/g range.
