Title: Round-robin ²³⁰Th–²³⁴U age dating of bulk uranium for nuclear forensics

Abstract

We report that in an inter-laboratory measurement comparison study, four laboratories determined ²³⁰Th–²³⁴U model ages of uranium certified reference material NBL U050 using isotope dilution mass spectrometry. The model dates determined by the participating laboratories range from 9 March 1956 to 19 October 1957, and are indistinguishable given the associated measurement uncertainties. These model ages are concordant with to slightly older than the known production age of NBL U050.

Application of the ²²⁶Ra–²³⁰Th–²³⁴U and ²²⁷Ac–²³¹Pa–²³⁵U radiochronometers to uranium certified reference materials

Journal Article Rolison, John M. ; Treinen, Kerri C. ; McHugh, Kelly C. ; ... - Journal of Radioanalytical and Nuclear Chemistry

Uranium certified reference materials (CRM) issued by New Brunswick Laboratory were subjected to dating using four independent uranium-series radiochronometers. In all cases, there was acceptable agreement between the model ages calculated using the ²³¹Pa–²³⁵U, ²³⁰Th–²³⁴U, ²²⁷Ac–²³⁵U or ²²⁶Ra–²³⁴U radiochronometers and either the certified ²³⁰Th–²³⁴U model date (CRM 125-A and CRM U630), or the known purification date (CRM U050 and CRM U100). Finally, the agreement between the four independent radiochronometers establishes these uranium certified reference materials as ideal informal standards for validating dating techniques utilized in nuclear forensic investigations in the absence of standards with certified model ages for multiple radiochronometers.

Mass spectrometric sup 230 Th- sup 234 U- sup 238 U dating of the Devils Hole calcite vein

Journal Article Ludwig, K R ; Simmons, K R ; Szabo, B J ; ... - Science (Washington, D.C.); (United States)

The Devils Hole calcite vein contains a long-term climatic record, but requires accurate chronologic control for its interpretation. Mass-spectrometric U-series ages for samples from core DH-11 yielding {sup 230}Th ages with precisions ranging from less than 1,000 years (2{sigma}) for samples younger than {approximately}140 ka (thousands of years ago) to less than 50,000 years for the oldest samples ({approximately}566 ka). The {sup 234}U/{sup 238}U ages could be determined to a precision of {approximately}20,000 years for all ages. Calcite accumulated continuously from 566 ka until {approximately}60 ka at an average rate of 0.7 millimeter per 10{sup 3} years. The precise agreementmore »« less

/sup 230/Th-/sup 234/U dating of pedogenic carbonates in gravelly desert soils of Vidal Valley, southeastern California

Journal Article Ku, T L ; Bull, W B ; Freeman, S T ; ... - Geol. Soc. Am., Bull.; (United States)

Radioactive disequilibrium relationships among /sup 230/Th, /sup 234/U, and /sup 238/U can be used to date pedogenic carbonates formed in regions of arid to semiarid climate. Samples suitable for dating consist of dense carbonate rinds around pebbles from the Cca soil horizon. Analytically, the method involves leaching the samples with dilute hydrochloric acid and measuring /sup 238/C, /sup 234/U, /sup 230/Th, and /sup 232/Th in both the leachate and residue fractions. As the soil carbonate commonly incorporates silicate mineral-bearing detritus, corrections are made to account for possible introduction of detrital /sup 230/Th and /sup 234/U into the acid leachate.

²³⁵U–²³¹Pa age dating of uranium materials for nuclear forensic investigations

Journal Article Eppich, Gary R. ; Williams, Ross W. ; Gaffney, Amy M. ; ... - Journal of Analytical Atomic Spectrometry

Here, age dating of nuclear material can provide insight into source and suspected use in nuclear forensic investigations. We report here a method for the determination of the date of most recent chemical purification for uranium materials using the ²³⁵U-²³¹Pa chronometer. Protactinium is separated from uranium and neptunium matrices using anion exchange resin, followed by sorption of Pa to an SiO₂ medium. The concentration of ²³¹Pa is measured by isotope dilution mass spectrometry using ²³³Pa spikes prepared from an aliquot of ²³⁷Np and calibrated in-house using the rock standard Table Mountain Latite and the uranium isotopic standard U100. Combined uncertaintiesmore »« less

International cooperation in age-dating uranium standards for nuclear forensics using the ²³¹Pa/²³⁵U radiochronometer

Journal Article Denton, Joanna S. ; Treinen, Kerri C. ; Chen, Yan ; ... - Journal of Radioanalytical and Nuclear Chemistry

During 2017–2018 Los Alamos National Laboratory, Lawrence Livermore National Laboratory and the China Institute of Atomic Energy collaborated in an interlaboratory ²³¹Pa/²³⁵U radiochronometry exercise. The laboratories used different analytical methods to obtain a consensus model purification date for CRM U010 of December 28, 1958 ± 198 days and for CRM U850 of May 20, 1958 ± 363 days. These results agree with previously reported model dates using the ²³⁰Th/²³⁴U radiochronometer as well as the production histories of these materials. The concordance of interlaboratory data here confirms the ability of laboratories to make reproducible radiochronometry measurements using distinct analytical approaches.
