摘要: Abstract Evaluation of the radiological significance Sellafield waste radionuclide discharges to Irish Sea requires characterisation redistribution processes affecting contaminated marine sediment, and investigations sediment concentration profiles are often used in this context. Results presented here for a study concentrations saltmarsh sediments south-west Scotland, which provide record deposition since 1960s. Comparison results with data discharge other studies indicates that dominant mechanism transport sites involves silt. It is also observed preserve time-integrated rather than annual variations. Temporal variations explained terms simple model includes effects dispersion/dilution silt redissolution. concluded that, provided do not increase substantially, continuation these will result decrease time pollutant being deposited, but an inventories accumulating intertidal sediments.
