Abstract

The present paper describes the individual analytical methodologies (Thermal Ionization Mass Spectrometry, Inductively Coupled Plasma Mass Spectrometry and Alpha Spectrometry) that were developed for uranium age determination and discusses their advantages and drawbacks. With respect to a potential application of the methods (e.g. Fissile Material Cut-off Treaty), the discussion focuses on highly enriched uranium, as this appears to be of highest strategic relevance. The different analytical methodologies were tested using uranium reference materials of different {235}U enrichments and of known ages.
