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)

“…Ondorioz, markatzaileen identifikazioa beharrezkoa da material nuklearraren trazabilitatearen jarraipena egiteko [80]. Hori dela eta, gaiari buruz adituak direnek (JRC Institute for Transuranium Elements, JRC-ITU) funtsezkoak diren parametroen identifikazioaren eta ezarpenaren garrantzia azpimarratzen dute behin eta berriz [81]. N. Grijalba Konfiskatutako material nuklearraren karakterizazio kimikoa egiteko giza aktibitateen aztarnak (fisiko zein kimikoak) edo erradiazio parametroak ikertzen dira.…”

Laburpena: 80ko hamarkadaz geroztik, laser bidezko ablazioa eta akoplamendu induktibozko plasma-masa espektrometria (LA-ICPMS) konbinatzen dituen teknika analitikoa sakonki ikertu eta garatu da, eta, gaur egun, lagin solidoen analisi elemental zein isotopiko zuzena egiteko erreferentziazko teknika bilakatu da. Ezaugarri bereizgarrienak hauexek dira: erabilpen erraza, analisi-denbora laburra, laginari eragindako kalte urriak, sentsibilitate handia eta elementu nagusi zein minoritarioen eta ratio isotopikoen aldibereko neurketa ahalbidetzen duen tarte dinamiko zabala. Lan honetan, LA-ICPMS teknikaren oinarriak eta konfigurazio orokorra azaldu eta femtosegundo/ nanosegundo laser bidezko ablazioaren erabileraren arteko desberdintasun nagusiak nabarmentzen dira. Azkenik, teknika honen egungo egoeraz jabetzeko, jatorri askotariko laginen analisi elementala laburbildu eta berrikusten da biologian eta ingurumenean, osasunean, geokimikan zein auzitegi zientzien alorretan.Hitz gakoak: Laser bidezko ablazioa (LA), akoplamendu induktibozko plasma-masa espektrometria (ICPMS), femtosegundo, nanosegundo, lagin solidoen analisi zuzena. Abstract:Since the early 80s, laser-ablation inductively-coupled-plasma mass spectrometry (LA-ICPMS) has been widely explored and nowadays is considered to be one of the most versatile analytical techniques for the direct trace elemental and isotopic analyses of solid samples. The most remarkable features are ease of use, fast sample throughput, limited sample damages, high sensitivity and wide dynamic range which allows the simultaneous acquisition of major and trace elements, as well as the meas-EKAIA 31.indd 45 EKAIA 31.indd 45

“…Process variables inherent in the synthesis of nuclear materials are known to influence the morphology of uranium oxide products [4,[6][7][8][9][10][11][12][13][14][15]. In particular, comparison of the morphology of precipitates with those of subsequent calcination products suggests that microstructures of the precursor precipitates are retained through heat treatment [6][7][8][13][14][15][16].…”

Changes in the visual characteristics of uranium oxide surfaces and morphology following storage under different conditions of temperature and relative humidity may provide insight into the history of an unknown sample. Sub-samples of three a-U 3 O 8 materials-one that was phase-pure and two that were phase-impure-were stored under controlled conditions for two years. Scanning electron microscopy was used to image the oxides before and after storage, and a morphology lexicon was used to characterize the images. Temporal changes in morphology were observed in some sub-samples, and changes were greatest following exposure to high relative humidity.
