- Abstract
Samples from a marine sediment core from the Irish Sea (54.416 N, 3.563 W) were analyzed for the isotopic composition of uranium, plutonium and americium by a combination of radiometric methods and AMS. The radiochemical procedure consisted of a Pu separation step by anion exchange, subsequent U separation by extraction chromatography using UTEVA (R) and finally Am separation with TRU (R) Resin.
Additionally to radiometric determination of these isotopes by alpha spectrometry, the separated samples were also used for the determination of U-236/U-238 and plutonium isotope ratios by Accelerator Mass Spectrometry (AMS) at the VERA facility.
