Variations of 210Po and 210Pb in various marine organisms from Western English Channel: contribution of 210Po to the radiation dose
International audience Measurements of 210Po were carried out in various marine matrices (mussels, oysters, seaweed, fish, and abalones) and in seawater at several points along the French coast, over a period of 2 years (2003-2005). These measurements contribute to a better knowledge of this element...
