Exploration of activity measurements and equilibrium checks for sediment dating using thick-window Germanium detectors

Warner, Jacob A; Fitzsimmons, Kathryn; Reynolds, Eva; Gladkis, Laura; Timmers, Heiko


Activity measurements on sediment samples for trapped-charge geological dating using gamma-ray spectroscopy are an important verification of the field-site dose rate determination. Furthermore gamma-ray spectroscopy can check if the natural decay series are in secular equilibrium which is a crucial assumption in such dating. Typically the activities of leading members of the Thorium and Uranium decay series are measured, which requires Germanium detectors with thin windows and good energy...[Show more]
