Monitoring of radioactivity along the French Mediterranean coast
Résumé
Since the beginning of the 90’s, IRSN realised sampling of bioindicators (mullet fishes and mussels) along the French Mediterranean coastline in order to (1) establish reference levels and (2) highlight the possible influence of nuclear installation/activities on the marine environment. Gamma analyses, conducted since
the beginning, are now completed by measurements of 3H(OBT), 14C, 241Am, 238Pu, 239+240Pu and allow to
obtain a new overview of the radiological influence of human activities on this environment. Additional
measurements of 210Po in fishes and mussels also used to best estimated the dose by ingestion for seafood
consumers.
Historical and spatial analyses are presented, and the influence of the different nuclear site/activities is
investigated
