Determination of U, Pu and Am isotopes in Irish Sea sediment by a combination of AMS and radiometric methods

Froehlich (previously Srncik) , Michaela; Hrnecek, E.; Steier, P; Wallner, Gabriele

Description

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® and finally Am separation with TRU® Resin. Additionally to radiometric determination of these isotopes by alpha spectrometry, the separated samples...[Show more]
