Modelling approach for environmental impact assessment from radioactive contamination of marine environment

One approach for modelling the consequences for the marine environment from radioactive contamination is promoted. The method is based on the modified approach for box modelling, which includes dispersion of radionuclides during time (non-instantaneous mixing in oceanic space). The model can provide information concerning the dispersion of radionuclides in water, sediment and biota phases of the marine environment. The assessment of internal and external doses to the marine organisms is based on assumptions about uniform distributions of radionuclides in organisms as well as surrounding water and sediment boxes.
