“…Despite this progress, no single parameter has yet been identified that is able to discern the identity and origin of unknown UOC samples. Increasingly, combined isotopic fingerprinting approaches are used to constrain the provenance and processing history of samples, and multivariate statistical techniques are used to discriminate between different sources of UOCs (Keegan et al 2008(Keegan et al , 2012(Keegan et al , 2014Bayne et al 2009;Robel et al 2009Robel et al , 2011Sirven et al 2009;Varga et al 2010). Likewise, approaches to chronometry have evolved over time, toward an increasing emphasis on obtaining concordant results from multiple parent, daughter, and granddaughter systems.…”

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)

“…As the resolution of portable spectrometers is generally not suffi cient to avoid spectral interferences on most matrices, LIBS is always used in association with chemometrics techniques. Sirven (2009) demonstrated in the case of powdered uranium concentrates (yellow cake) that LIBS combined with PCA can discriminate samples from 11 different geographical origins, and Doucet et al . (2011) performed isotope ratio analysis of uranium and hydrogen.…”

“…The nuclear forensics is one such application where LIBS has found significant application [1]. Several studies have demonstrated the ability of LIBS to detect nuclear material in matrices relevant to the nuclear community, such as geological deposits [2,3], uranium ores [4,5], and surrogate nuclear debris [6]. Other studies validated the use of LIBS in nuclear safeguard applications, including analysis of IAEA swipe samples [7], nuclear reprocessing plant activities [8], and standoff detection of radiological threat materials [9].…”

A hand-held laser-induced breakdown spectroscopy device was used to acquire spectral emission data from laser-induced plasmas created on the surface of cerium-gallium alloy samples with Ga concentrations ranging from 0 to 3 weight percent. Ionic and neutral emission lines of the two constituent elements were then extracted and used to generate calibration curves relating the emission line intensity ratios to the gallium concentration of the alloy. The Ga I 287.4 nm emission line was determined to be superior for the purposes of Ga detection and concentration determination. A limit of detection below 0.25% was achieved using a multivariate regression model of the Ga I 287.4 nm line ratio versus two separate Ce II emission lines. This LOD is considered a conservative estimation of technique's capability given the type of the calibration samples available and low power (5 mJ per 1 ns pulse) and resolving power (λ/∆λ = 4000) of this handheld device. Nonetheless, the utility of the technique is demonstrated via a detailed mapping analysis of the surface Ga distribution of a Ce-Ga sample which reveals significant heterogeneity resulting from the sample production process.
