|Abstract:||A simple and rapid method has been developed for the direct determination of the age (i.e. the prodution date) of uranium-containing nuclear materials by inductively coupled plasma mass spectrometry based on the measurement of the 230 Th/234 U radionuclide ratio. The concentration of the trace-level 230 Th in the samples was measured directly without the need of prior chemical separation. the tailing of the highly abundant 238 U peak, which is tipically around 10 orders of magnitude higher that that of the 230 Th signal, was eliminated by the matematical deconvolution of the measured mass spectrum. The 230 Th and 234 U contents were quantified by isotope dilution method. thje developed method was validated using reference materials of known production date.|
