“…Laser ablation multi-collector inductively-coupled plasma mass spectrometry (LA-MC-ICP-MS) has seen a recent increase in application since the introduction of laser-induced breakdown spectroscopy in the 1980s [46][47][48][49][50][51][52][53][54]. Continuous-wave CO2 lasers remain the preferred method due to their power, wide availability, and wide application.…”

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.

“…One such effort has been the development of surrogate nuclear debris for laboratory and field training exercises. Several debris formulations have been developed at laboratories including Idaho National Laboratory, 3 Los Alamos National Laboratory, 4 Lawrence Livermore National Laboratory, 5 the Pacific Northwest National Laboratory, 6–8 and the University of Tennessee. 9–11 Early versions of these formulations used trinitite, the debris formed from the first nuclear weapons test, as a benchmark since trinitite is openly available and has been well characterized.…”

“…Different synthesis approaches have also been explored including the melting of precursor ingredients in a box furnace as proposed by Nizinski 22 and formation by high power continuous wave (CW) CO 2 laser irradiation as suggested by Liezers. 7 Each variant holds potential advantages and disadvantages; in each case, the surrogate material characterization is essential to determine the degree to which it replicates our expectations for the morphology, chemical and radio-analytic properties of actual debris.…”

Mapping of Uranium in Surrogate Nuclear Debris Using Laser-Induced Breakdown Spectroscopy (LIBS)

et al. 2019

This work describes the use of a laser-induced breakdown spectroscopy (LIBS) system to conduct macroscopic elemental mapping of uranium and iron on the exterior surface and interior center cross-section of surrogate nuclear debris for the first time. The results suggest that similar LIBS systems could be packaged for use as an effective instrument for screening samples during collection activities in the field or to conduct process control measurements during the production of debris surrogates. The technique focuses on the mitigation of chemical and physical matrix effects of four uranium atomic emission lines, relatively free of interferences and of good analytical value. At a spatial resolution of 0.5 mm, a material fractionation pattern in the surrogate debris is identified and discussed in terms of constituent melting temperatures and thermal gradients experienced.
