Under the collaboration between EC-JRC and JAEA, the in-situ age dating method was subject to joint validation, and six different uranium materialswere used for this purpose. The age dating result by in-situ isotope method was consistent with known production dates of the respective samples. The uncertainty evaluation according to GUM for the in-situ isotope method indicates that the measured Th/Th ratio provides the highest contribution. The accuracy of in-situ isotope method can be improved by higher precision in Th/Th measurement.
