Radiochemical measurements of the concentrations of thorium and uranium isotopes were carried out for a total of 10 samples of hot springs, mineral springs, and lakes collected in the vicinity of the Nevada Test Site. The uranium-to-thorium ratios in the water samples were found to be generally much greater than those in soils and in rain water. The apparent (230)Th ages calculated from the (230)Th/(232)Th and (234)U/(238)U ratios for most of these water samples were less than 100 years.
