Abstract (English)

In this work, the significance of the determination of the ratio of the activity concentrations of 228Th and 232Th in the context of age determination of ivory was discussed and the corresponding dating uncertainty was reduced. Calibration curves for the relevant isotopes for ivory dating, namely 14C, 90Sr and 228Th/232Th, were created by analyzing young ivory samples with known age. It was shown ...

Translation of the abstract (German)

Im Zuge dieser Arbeit wurde die Bestimmung des Aktivitäten Verhältnisses von 228Th und 232Th zum Zwecke der Altersdatierung von Elfenbein weiterentwickelt. Die Bedeutung der Methode wurde diskutiert und deren Datierungsunsicherheit reduziert. Es wurden Kalibrierkurven für die datierungsrelevanten Isotope 14C, 90Sr und 228Th/232Th erstellt, indem junge Elfenbeinproben bekannten Alters analysiert ...
