A comparison of marine radionuclide dispersion models for the Baltic Sea in the frame of IAEA MODARIA program

Four radionuclide dispersion models have been applied to simulate the transport and distribution of 137Cs fallout from Chernobyl accident in the Baltic Sea. Models correspond to two categories: box models and hydrodynamic models which solve water circulation and then an advection/diffusion equation....
