Radium-226 Measurements Below Uranium-Mill-Tailings Piles
A total of 2773 Ra-226 in-soil measurements have been made in and beneath 12 uranium mill tailings piles. Four conditions were found beneath the piles: (1) rock, with essentially no contamination; (2) very dry soil with contamination of 1000 pCi/g above the interface to 15 pCi/g at 7.5 feet below the interface; (3) near-saturated to saturated soils with contamination similar to condition 2; and (4) saturated soils underlaid by cobbles and water where the water contained very fine particles of Ra-226 in suspension. A number of exceptions to the above conditions were found during this study. Vertical-profile holes of the tailings, using 2.5-foot core-barrel samplers, exhibited activities from > 2000 pCi/g to approximately 15 pCi/g. This paper describes the counting system used to determine Ra-226 and the resulting data. (ERA citation 07:049418)
