    Abstract

    The present report deals with the measurement of fall-out radioactivity in Denmark in 1973. Strontium-90 was determined in samples from all over the country of precipitation, soil, ground water, stream and lake water, sea water, grass, dried milk, fresh milk, grain, bread, potatoes, vegetables, fruit, total diet, drinking water, and human bone. Furthermore 90Sr was determined in local samples of air, rain water, grass, sea plants, fish, and meat. Caesium-137 was determined in soil, sea water, milk, grain products, potatoes, vegetables, fruit, total diet, and meat, and 137Cs was measured by wholebody counting in persons from a control group at Risø. Estimates of the mean contents of radiostrontium and radiocaesium in the human diet in Denmark inl 973 are given. The Y-background was measured regularly at locations around Risø, at ten of the State experimental farms and in an area in Zealand, one in Jutland where future nuclear power plants might be located, and along the shores of the Great Belt. Finally the report includes, as previously, regular purveys of environmental samples from the Risø area.
