POSEIDON: A Dispersion Computer Code for Assessing Radiological Impacts in a Marine Environment

At the request of the French Nuclear Protection and Safety Institute, the CEPN has developed a dispersion computer code to assess at medium and long time scales the evolution of the radiological consequences associated with a radioactive release in European sea waters. The general methodology and the physical parameters have been derived from the EC 'Marina' project and EC RP 72 report. The specificity of the modeling is that it integrates the daughter products and operates under a Windows environment on PC computers.
