Abstrakt

Recently, the anthropogenic uranium isotope U-236 has been recognized as one of the "environmental uranium (U) isotopes". With the development of instruments and detection techniques of sufficient abundance sensitivity, the applications that use U-236 as a proxy/tool for environmental and geochemical uranium studies are expanding. The origin and level of U-236 in the vicinity area of the Japan Sea were deduced from measurements of U-236 and Cs-137 in surface soils, seawater, suspended particulate matter and oceanic bottom sediments. This study also presents the feasibility of U-236 use as an oceanic circulation tracer.
