Studies of Long-Term Ecological Effects of Exposure to Uranium V.
Abstract
Research performed by the Los Alamos Scientific Laboratory for the Air Force Armament Laboratory, Eglin Air Force Base, Florida, is reported. A Statistical Technique known as kriging was used to analyze the uranium concentrations in surface soil at E-F Site (LASL). Kriging provided a much more realistic contour surface for U concentrations than either a polynomial trend analysis or contouring the original data. The major advantages of kriging are: (1) a measure of the uncertainty of the contoured surface is provided, and (2) the nonparametric nature of the method allows very irregular surfaces to be fitted. A function relating the counting efficiency for uranium of the phoswich portable survey instrument to ambient temperature (10 C-30 C) was developed. Counting efficiency is maximum at approximately 10 C and declines significantly for higher temperatures. Soil moisture and relative humidity were also considered, but did not affect the counting efficiency of the phoswich. (Author)
