Estimating the risk of top predator contamination via tracing the 137Cs activity in the marine food web (AMORAD)

This French (ANR-Investissement d’Avenir) research project  AMORAD (Improvement of radionuclides dispersion modeling and impact assessment in the environment) led by IRSN is studying the transfer of radionuclides in sediments and marine organisms as a result of catastrophic accidents (e.g., Fukushima).  The mechanisms of transfer and accumulation of radioactive 137Cs in the marine food web are investigated and included in a new coupled SEAPODYM and radioecological model.

An operational model will be then implemented to produce the maps of risk indicators that could be helpful in monitoring and  sampling strategy development in case of radionuclide release in marine environment.
