Natural and anthropogenic radionuclides in Norwegian farmed Atlantic salmon (Salmo salar).

Norway is one of the main producers of farmed fish and the world's second-largest exporter of seafood. Farmed Atlantic salmon (Salmo salar) represents the most exported species. This is the first comprehensive survey of anthropogenic (Cs, Sr, Pu, Pu and Am) and natural (K, Ra, Ra, Pb, Po) radionuclides in farmed salmon and manufactured fish feed from Norway.
