[en] New techniques that could assist law enforcement officers in the evaluation of radioactive materials of unknown provenance are required. This paper provides preliminary results on a new method for iridium metal dissolution using pressure digestion vessels and hydrogen peroxide, which has been developed for use in forensic applications. The results were generated using iridium powder as a surrogate, but it is anticipated that the method will be directly transferable to iridium source materials. (author)

[en] Samples of materials involved in the conversion of uranium into nuclear-grade products are collected to support the verification of States' declarations and to look for indications of possible undeclared materials and activities. Samples are analysed by several laboratories to determine concentrations of about sixty impurities; the data consistency is addressed through the unified reporting requirements, the use of common reference materials, and via inter-laboratory comparisons. The impurity analysis results, along with other essential parameters, are interpreted to judge sample conformity to the relevant specifications, to evaluate the facility design information, to assess material provenance and intended use.

[en] The paper will discuss an array of TTX-based nuclear forensics training tools that are being used and developed, with a more thorough explanation of the Tabletop Cooperative Simulation Exercises (TCSE). Discussion will suggest guidelines and resources for preparing an exercise appropriate to training goals within a systematic approach. This work is intended to bolster international efforts to deliver nuclear forensics training offerings that are well characterized within best practices. (author)

[en] During the last years a coherent program started in IFIN-HH with the aim of establishing the first dedicated nuclear forensics laboratory in Romania. The steps taken in the implementation of this program are presented, with some results obtained our R&D activity. (author)

[en] Different approaches to interpretation of the same analytical results as well as of the same information are demonstrated. Examples of TTX “Glowing Tulip” as well as of one real investigation are considered. Possible reasons of different results of analysis of the same data are mentioned and discussed. (author)

[en] Forensic science seeks to predict source characteristics using measured observables. Statistically, this objective can be thought of as an inverse problem where interest is in the unknown source characteristics or factors (X) of some underlying causal model producing the observables or responses (Y = g (X) + error). Here, this paper reviews several statistical methods for use in inverse problems and demonstrates that comparing results from multiple methods can be used to assess predictive capability. Motivation for assessing inverse predictions comes from the desired application to historical and future experiments involving nuclear material production for forensics research in which inverse predictions, along with an assessment of predictive capability, are desired.

[en] The University of Tennessee formed its Radiochemistry Center of Excellence (RCoE) in 2013 with support from the U.S. National Nuclear Security Administration. One of the major thrusts of the RCoE is to develop deeper understanding of rapid methods for radiochemical separations that are relevant to both general radiochemical analyses as well as post-detonation nuclear forensics. Early work has included the development and demonstration of rapid separations of lanthanide elements in the gas phase, development of a gas-phase separation front-end for ICP-TOF-MS analysis, and the development of realistic analytical surrogates for post-detonation debris to support methods development.
