“…The standard most relevant to nuclear forensic methods is the Daubert standard, as it applies to the Federal Rules of Evidence, Article 7, Rule 702 [5][6][7]. Based on the Daubert standard, judges are given means by which they can assess an expert's scientific testimony on the grounds of reasoning or methodology.…”

“…Application of this forensics standard has rightly received rigorous attention in the scientific community [5,[8][9][10][11]. In addition, the National Institute of Standards and Technology (NIST) and other researchers are establishing certified reference materials (CRMs) and recognized databases of nuclear information that may act as a known standard for other nuclear materials [12].…”

Deterring nuclear terrorism is a critical national asset to support the preclusion of non-state actors from initiating a nuclear attack on the United States. Successful attribution of a detonated nuclear weapon, which includes locating the source of the radiological materials used in the weapon, allows for timely responsive measures that prove essential in the period following a nuclear event. In conjunction with intelligence and law enforcement evidence, the technical nuclear forensics (TNF) post-detonation community supports this mission through the development and advancement of expertise to characterize weapon debris through a rapid, accurate, and detailed approach. Though the TNF field is young, numerous strides have been made in recent years toward a more robust characterization capability. This work presents modern advancements in post-detonation expertise over the last ten years and demonstrates the need for continued extensive research in this field.

“…In nuclear forensics, it is important that the accuracy and precision are maximized, in other words, it is important that the measurement uncertainties are well-understood and fit-for-purpose to make comparisons between materials useful [8,9]. Therefore, an overestimation of certain elements may be detrimental to the use of a measurement result.…”

Measurements of the lanthanide series with ICP-SF-MS provide low detection limits but suffer from oxides of the lighter lanthanides interfering on the heavier ones. In this work, two different methods to measure the lanthanide series without interferences, were investigated and compared to measuring the lanthanides directly with a standard sample introduction system. It is shown that by using a desolvating sample introduction system during measurements, the impact of polyatomic interferences are eliminated. It is also shown that using chemical separations to separate the elements in the lanthanide series into three fractions almost eliminates polyatomic interferences, while direct measurements with a standard sample introduction system may lead to inaccurate results due to interferences.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…In consequence, an emerging need for such materials has been recently expressed by the community involved in nuclear security programs (Inn et al, 2013;Leggitt et al, 2009). In practice, due to the lack of radiochronometry reference materials, already available reference materials certified only for major isotopic composition are used by nuclear forensic laboratories as a pragmatic solution to check the accuracy of their measurement results by comparing them with the reasonably well-known dates of final purification of these materials (usually referred to as assumed or archive ages) (Gaffney et al, 2009;Wallenius et al, 2002).…”

The results of a joint effort by expert nuclear forensic laboratories in the area of age dating of uranium, i.e. the elapsed time since the last chemical purification of the material are presented and discussed. Completely separated uranium materials of known production date were distributed among the laboratories, and the samples were dated according to routine laboratory procedures by the measurement of the (230)Th/(234)U ratio. The measurement results were in good agreement with the known production date showing that the concept for preparing uranium age dating reference material based on complete separation is valid. Detailed knowledge of the laboratory procedures used for uranium age dating allows the identification of possible improvements in the current protocols and the development of improved practice in the future. The availability of age dating reference materials as well as the evolvement of the age dating best-practice protocol will increase the relevance and applicability of age dating as part of the tool-kit available for nuclear forensic investigations.
