Distribution of 137Cs and 90Sr in various tissues and organs of freshwater fish in Finnish lakes
The degree of radiocontamination in fish is usually analysed to estimate doses to fish consumers, for which the radionuclide contents in the edible parts of fish are needed. Recently increasing attention has been focused on radiation protection in plants and animals. To estimate the effects of radia...
