Abstract

The development steps of the radiological box model of the Aegean Sea are presented here. The applied methodology combines all the available and necessary site specific information. The modelling approach includes terms describing the radionuclide dispersion into oceanic space with time (non-instantaneous mixing), while the model’s algorithms also cover whole processes of radionuclides’ transfer, bioaccumulation and doses assessment. The model includes 50 marine and sediment boxes, optimized based on experimental radiocesium measurements followed the Chernobyl accident. The process is expected to reveal the key parameters controlling the radionuclides’ fate as well as their effect on the model’s prediction.
