Fukushima Daiichi Nuclear Accident Monitoring, Taylor Wilson at University of Nevada, Reno, April 17, 2011:
To test different types of Soil, a sample was collected from the base of the Sierra Nevadas. This soil is less sandy, and more organic, which would suggest a higher coefficient for sorption for Radionuclides. It also has more moisture content. The data is still preliminary however, there appears to be ~700 pCi/kg or ~26 Bq/kg of Cs137. Which is ~30 times the amount present in Valley soil.
