Sumario:The paper describes the applicability of different characteristics (signatures) in nuclear safeguards and forensics for assessment of uranium material provenance in terms of production process. The study follows a uranium ore concentrate production from an ore to a U(3)O(8) product. It turned out that rare-earth elemental pattern, radiochronometry (age of ore body and material production date), sulphur and organic impurities are useful to find out the origin or history of the material, while certain trace-elements and isotopics of Pb or Sr were found to be inconclusive. The results will be important to understand the signatures in nuclear safeguards and forensics. ELECTRONIC SUPPLEMENTARY MATERIAL: The online version of this article (doi:10.1007/s10967-017-5247-5) contains supplementary material, which is available to authorized users.
