Ingestion doses in Finland due to 90Sr, 134Cs, and 137Cs from nuclear weapons testing and the Chernobyl accident

90Sr and 137Cs in domestic foodstuffs and water have been analysed in Finland since the early 1960s, and 134Cs since 1986. Using data on radionuclide deposition levels, agricultural production, and the processing and consumption of foodstuffs, the average intake and radiation dose from the ingestion of these radionuclides have been assessed. The estimated committed effective dose from the ingestion of 90Sr, 137Cs, and 134Cs in food and water for the period 1960–2005 is 2.2 mSv, and for the period since the Chernobyl accident in 1986 it is 1.3 mSv.
