First study on 236U in environmental samples from Bangladesh by ICP-MS/MS prior to the operation of its first nuclear power plant

Deciphering sources of U contamination using isotope ratio signatures in the Loire River sediments: Exploring the relevance of 233U/236U and stable Pb isotope ratios

“…global fallout and NPP accident), the lack of a second anthropogenic uranium isotope is a disadvantage compared to plutonium for the source identification: 236 U/ 238 U ratio variation depends on the dilution with natural U. For the Loire River, it is clear that the 236 U/ 238 U ratio variation fits within the global fallout range (10 -9 to 10 -6 ) (Alam et al, 2021;Liu et al, 2020;Quinto et al, 2013;Sakaguchi et al, 2010Sakaguchi et al, , 2009Srncik et al, 2011a;Wang et al, 2021;Yang et al, 2019), thus making a reliable identification of possible other U emission sources challenging.…”
