dc.description.abstractWhile environmental sampling is a well established nuclear safeguards tool, the information contained in measurements performed on radioactive environmental samples may also be of use for nuclear forensic purposes. Nuclear forensics (NF) is the scientific analysis of nuclear or radioactive material, or of evidence that is contaminated with radioactive material, in the context of legal proceedings [1]. Piecing together collected evidence, for instance in the case of a detonated radiological dispersal device (RDD), may provide clues as to the provenance of the material involved in such nuclear security events. Research in this area involves profile analysis on radioactive or nuclear materials and debris identifying parameters, such as isotopic composition, which constitute a unique ‘signature’ of the material, potentially leading to attribution. This paper will outline the research activities of ANSTO’s recently established Nuclear Forensic Research Facility (NFRF) and its endeavors in performing measurements on environmental samples within the context of nuclear forensics. For instance, uranium mining and milling are a potential source of contamination of the environment with radioactive material. Work carried out by the NFRF has demonstrated that even particle sized samples of uranium ore concentrate (UOC) can be tracked back to the mine from which it originated. New analytical capabilities within NFRF will be presented and discussed. For example, the 231Pa/235U isotope chronometer while being developed for NF purposes can also be readily applied to environmental monitoring.en_AU
