Gamma spec. of natural soil

[Mr Jo <mjo@scs.unr.edu>]

To soil samplers and analyzers:

I took natural soil samples from the depths of 0, 2, 4, 6, 8, and 10 feet from
one location. There were no Cs-137 peaks from the samples taken at 4 feet and
deeper. Is this normal? This area is dry and average rainfall is less than 10
inches per year (I think). I used Genie2K + extended range HPGe for this
analysis. Thank you. M. Jo
