Thorium-230 dating of natural waters at the Nevada Test Site

摘要

Radiocarbon determinations have been used in the past to estimate the ages of groundwater from the Paleozoic aquifer underlying the Nevada Test Site and adjacent areas. We measured the concentrations of (sup 230)Th, (sup 232)Th, (sup 234)U and (sup 238)U in several water samples taken from the wells and spring at the Nevada Test Site and calculated the (sup 230)Th ages. 2 refs.
