“…Work byŠvedkauskaitė- LeGore et al (2008) identified the utility of elemental impurity data in conjunction with Pb isotope data in identifying the origin of uranium ore samples. In a comprehensive study of Australian UOCs, Keegan et al (2008) analyzed uranium and lead isotopes and 23 trace elements in samples from three active mines in Australia.…”

Nuclear forensic science seeks to identify the origin of nuclear materials found outside regulatory control. It is increasingly recognized as an integral part of a robust nuclear security program. This review highlights areas of active, evolving research in nuclear forensics, with a focus on analytical techniques commonly employed in Earth and planetary sciences. Applications of nuclear forensics to uranium ore concentrates (UOCs) are discussed first. UOCs have become an attractive target for nuclear forensic researchers because of the richness in impurities compared to materials produced later in the fuel cycle. The development of chronometric methods for age dating nuclear materials is then discussed, with an emphasis on improvements in accuracy that have been gained from measurements of multiple radioisotopic systems. Finally, papers that report on casework are reviewed, to provide a window into current scientific practice. Ian Hutcheon, our friend, colleague, and mentor, passed away on March 26, 2015, during the writing of this review paper. Ian (PhD, Physics, University of California, Berkeley, 1974)

“…Due to nuclear security issues, knowing the origin of uranium-bearing materials is important. Švedkauskaitè-LeGore et al [65] demonstrated the usefulness of a combined approach determining Pb isotopes by multi-collector ICP-MS (MC-ICP-MS) and trace elements by ICP-MS (66 variables). The results from a set of 35 uranium ore samples and 10 yellow cake samples were evaluated using cluster analysis.…”

Analytical Proof of Origin for Raw Materials

Growing public interest in getting information on the origin of raw materials used to manufacture goods for daily life has triggered the development of concepts to increase the transparency of raw material supply chains. Analytical proofs of origin (APOs) for raw materials may support those transparency concepts by giving evidence about the origin of a specific raw material shipment. For a variety of raw materials like gemstones, TTT (tantalum, tin, tungsten) minerals, and others, APOs have been developed. The identification of features that distinguish different origins, databases of those features from reliable reference samples, and a data evaluation strategy adopted to the envisaged application scenario are the key aspects of APO methods. Here, an overview is given on APO methods developed for different raw materials and application cases.

“…Svedkauskaite-LeGore and colleagues collected 35 uranium ore and 10 yellow cake samples from different mines world-wide and then used ICP-MS to determine their impurities. 248 Use of pattern recognition techniques such as cluster analysis on the analytical data enabled the samples to be characterized according to their geographical origin. The results apparently showed a clear relationship between samples of the same region and the authors concluded that a satisfactory fingerprinting method had been developed.…”
