Nuclear forensic analysis on uranium ore concentrates: A multi-laboratory intercomparison study
摘要
A collaboration between the United States and Japan performed nuclear forensic analyses on a set of 7 uranium ore concentrate (UOC) samples with known origins to improve methodologies and best practices in the field. Overall, good agreement between the 4 participating laboratories was achieved for uranium assay, uranium isotope composition, strontium isotope composition, and trace element analysis. The combination of these four signatures is sufficient to distinguish the different origins among these studied UOCs.
