    Strontium-90 was determined in samples from all over the country of precipitation, ground water, sea water, dried milk, grain, bread, potatoes, vegetables, fruit, total diet, and an human bone. Furthermore, 90Sr was determined in local samples of air, rain water, 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 1984 are given. Tritium was determined in precipitation, ground water and sea water. Polonium-210 was measured in some marine samples. Radium-226 was determined in ground water. The Y-background was measured regularly by TLD, ionization chamber and on site Y-spectroscopy at locations around Risø, at ten of the State experimental farms, along the coasts of the Great Belt and around Gylling Næs. The marine environments at Barseback and Ringhals were monitored for 137Cs and corrosion products (58Co, 60Co, 65Zn, 54Mn).
