摘要

This paper explores the feasibility of using U–Th isochrons as a tool to help interpret ²³⁰Th–²³⁴U model ages derived from uranium metal samples. We introduce the basic concepts of the isochron, including the conditions required to produce a meaningful isochron from U–Th isotope data. Then, using examples from cast uranium metal samples, show how isochrons can be used to guide our understanding of the assumption of purification in a ²³⁰Th–²³⁴U model-age, and provide additional age data that can used to aid nuclear forensic investigations.
