Abstract:
The variation of uranium-238 (U) and thorium-232 (Th) in metallurgical slags and ores, withextension in metals, is examined using alpha scintillation counting. Data indicate a great variability:0.1 to 12ppmforUand0to3ppmforTh, while Th/U <1. These isotopic data coupled with the ratioRa-226/ Th-230 in the U-series disequilibrium in ancient metal objects offer a potential means of datingancient metals.
