Summary:Sequential leaching of Clyde sea area and Loch Etive sediments suggests that partitioning of Sellafield (formerly Windscale)-derived 137Cs is related, to a larger than expected extent, to the concentration of sedimentary oxides, organics and, less importantly, carbonates. These components act to prevent 137Cs release from clay mineral exchange sites. Leaching of wet sediments appears to provide quite different and presumably more realistic information on nuclide associations relative to that produced by leaching dry sediments. The latter 137Cs partitioning data appear to overestimate the degree of 137Cs fixation in these coastal deposits. The observed partial association of 137Cs with non-clay constituents means that diagenetic remobilization of the nuclide is in theory feasible and a preliminary study suggests its occurrence to a minor degree.
