Tittel

REMOTRANS

Sammendrag

The aim of the project is to study remobilisation of radiologically important radionuclides from sediments of different characteristics in European environments. Transboundary exposure has to be taken into account into the modelling and assessment of commited doses. The radiological consequences will be evaluated by the study of long-range transport of the radionuclides, their speication, uptake in biota and radioecological modelling. The objectives will be achieved through collaboration between experienced scientists regarding field sampling, laboratory experiments and analytical methods using latest techniques. The results will create a more precise knowledge of long-term effects on environment and man from present and past sources and a more informed debate on waste management or controlled release of radioactivity in the marine environment. AUN will:· provide input data for long range marine transport and essential for the source term,· information on o processes controlling radionuclide remobilisation from contaminated oxic and anoxic sediments, with emphasis on the role of environmental parameters, radionuclide speciation and solid partitioning (including colloids) in sorption/desorption processes at the sediment-water interfaceo the bioavailabilty of artificial radionuclides which have been remobilised from sediments in the aquatic environment. · to improve the methodology for describing sediment-water interactions and transport models with special regards to the study of the mechanisms for remobilisation and bioavailability.
