I have an old document from the State of Oregon's Radiation Control Division. It shows data from 1961-1983 on
environmental radiological surveillance of Oregon's soils. A quick look shows that most of the Cs-137 values from
1984-1990 are at ~1-2 pCi/g with some peak values at 7-8 pCi/g. These peak values are most likely from drainage
areas.
