“…Considering a codispersion between radionuclides and Pb originating from the U-mine, Pb isotope fingerprinting allowed highlighting of the dissemination of radionuclide-enriched materials in the environment and calculating their percentage of impact. ,,,,,− Pilot studies have also shown the possibility of using Pb isotopes in blood samples as an exposure indicator of U-mine employees on radioactive dusts . The isotopes of Pb were also used in the field of nuclear forensics for the identification of the origin of U-ores and U-ore concentrates (yellowcake). − …”

“…evaporation, condensation, diffusion, isotopic exchange, radiometric decay, etc.). Specifically, isotopes of Pb are of particular importance in archaeology, Earth and planetary science, and other scientific fields because they provide insights into the origin of the material [1,2]. For example, the isotopic ratio of Pb can identify the production area of archaeological artefacts (e.g.…”

Elemental isotopic ratios are measured in various research fields and provide useful information regarding age, origin, geological and biological activities, ancient climate, etc. Here, we report a new isotopic analysis method without sample destruction using muon-induced characteristic X-rays. We demonstrated this method by conducting muon-beam irradiation experiments on two Pb plates with different isotopic ratios: natural isotopic composition and artificially enriched 208 Pb. The observed broad X-ray peaks of the Pb K α line around 6 MeV were deconvolved with 206 Pb, 207 Pb, and 208 Pb isotopes, giving the isotopic ratios. The resulting isotopic ratios were consistent with those obtained from mass spectrometry.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…Measuring the stable isotope such as Lead (Pb) is an established technique in geolocation [6,15]. Natural Pb is composed of four stable isotopes, and the International Union of Pure and Applied Chemistry (IUPAC) [16] reports small natural variations on the representative isotopic composition: 204 Pb-1.4%, 206 Pb-24.1%, 207 Pb-22.1% and 208 Pb-52.4%.…”

“…Applying Nuclear Forensics as a fingerprinting tool to compare with reference data allows the researcher to determine the origin, the intended use, the last legal owner and the smuggling route of the nuclear or radioactive material [6]. This makes Nuclear Forensics to be a key element of Nuclear Security.…”

In this work, a total of twenty samples selected for investigation originate from South Africa and Namibia uranium mines. The aim of this study was to determine whether the lead ratios measured in particular samples could be used to attribute the uranium sample to the production or reprocessing plant. Measurements were carried out using an inductively coupled plasma mass spectrometer PerkinElmer NexION 2000. The precision obtained for the 208 Pb/ 206 Pb ratio, the 207 Pb/ 206 Pb ratio and the 204 Pb/ 206 Pb ratio values was considerably lower than 0.02% demonstrating the applicability of the technique for Pb isotope ratio studies.
