The present report deals with the measurement of fall-out radioactivity in Denmark in 1976. Strontium-90 was determined in samples from all over the country of precipitation, soil, ground water, sea water, grass, dried milk, fresh milk, grain, bread, potatoes, vegetables, fruit, total diet, 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, fish, and meat. It was also
measured by wholebody-counting of a control group at Risø. Estimates of the mean contents of radiostrontium and radiocaesium in the human diet in Denmark during 1976 are given. The y-background was measured regularly at locations around Risø, and ten of the State experimental farms. The marine environments at Barsebäck and Ringhals were monitored for 137Cs and corrosion products. Finally the report includes routine surveys of environmental samples from the Risø area. Results of plutonium determinations in soil and sediments from 1975 and in grain from 1963 and 1965 are presented in this report.
