    Abstract

    Strontium-90 was determined in samples from all over the country of precipitation, ground water, drinking water, sea water, dried milk, grain, bread, potatoes, vegetables, fruit, total diet, and human bone. Furthermore, 'uSr was determined in local samples of air, rain water, marine sediments, grass, sea plants, fish and meat. Cesium-137 was determined in, air, precipitation, sea water, sediments, milk, grain products, potatoes, vegetables, fruit, total diet, sea plants, fish, and meat. Estimates of the mean contents of radiostrontium and radiocesium in the human diet in Denmark during 1982 are given. Tritium was determined in precipitation, fresh water and sea water. Plutonium and Americium were measured in sra water, sediments, sea plants and mussels. The ϒ-background was measured regularly by TLD, ionization chamber and on site ϒ-spectroscopy at locations around Risø, at ten of the State experimental farms along the coasts of the Great Belt and around Gylling Nas. The marine environments at Barseback and Ringhals were monitored for 137Cs and corrosion products (58Co, 60Co, 65Zn, 54Mn).
