“…Gamma-ray analysis for actual trinitite has already been carried by a number of groups including Eppich et al, [3,[5][6][7][8][9][10][11][12]. These results are used as a basis for comparison of the trinitite to the surrogate samples developed in this work.…”

The development of realistic nuclear melt glass surrogates is important to the nuclear forensics community in order to establish analytical protocols for post-detonation analysis. In addition to creating surrogates that are accurate with regard to physical morphology and chemical composition, it is important to develop surrogates that also have similar radiological characteristics. A synthetic melt glass sample was irradiated at the High-Flux Isotope Reactor at Oak Ridge National Laboratory. This sample was counted twice using a semiconductor radiation detector to capture both fission-product signatures as well as those from neutron activation. A qualitative and quantitative analysis was performed to make recommendations for the next irradiation campaign.

“…The individual lanthanides Nd and Gd are removed using a Dowex AG50W x 8 (30 × 5 cm) column pre-treated with NH4 + to remove the H + , with subsequent elution using α-HIBA (α-hydroxyisobutyric acid) at a pH of 4.7. The cuts are dried and dissolved in 0.8M HNO3 [55]. Eppich et al [64] reports a similar process prior to performing analysis, wherein the matrix elements are removed using a 1.8mL U-TEVA ion exchange resin conditioned with 10mL of 4M HNO3.…”

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 addition to the first row transition elements, the separation of other elements found in the melt glass debris are also of interest, such as Group 1 and 2 elements and the actinides. [8][9][10][11]. Therefore, this separation of urban melt glass, which consists of both cement and glass, with the intent to separate some of the first row transition metals using DGA resin, is unique.…”

A new method was developed for separating Co, Fe, and Sc from complex debris matrices using the extraction chromatography resin DGA. The activation products Co-58, Mn-54, and Sc-46 were used to characterize the separation of the synthetic melt glass solutions. In the separation scheme that was developed, Au, Co, Cu, Fe, Sc, and Ti were separated from the rest of the sample constituents. In this paper, the synthetic melt glass separation method, efficiency, recoveries, and the length of procedure will be discussed. Batch contact adsorption studies for Na and Sc for DGA resin are discussed as well.
