چکیده

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 U3O8 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.

The paper describes the preparation and production of the reference materials, IRMM-1000a and IRMM-1000b, certified for the production date based on the 230Th/234U radiochronometer in compliance with ISO Guide 34:2009. The production date of the reference materials corresponds to the last separation of 230Th from 234U, i.e. when the initial daughter nuclide content in the material was finally r...

Isolation and identification of native sulfuroxidizing bacterium capable of uranium extraction

Bioleaching is the extraction of metals from their ores through the use of microorganisms. Inthis process, the use of native bacteria leads to achieve more yields of metals. So, in the presentstudy, native sulfur-oxidizing bacterium in potentiality of uranium extraction was isolated fromGhachin mine in Iran and identified by partial gene sequencing. For this purpose, the watersamples were colle...
