    Abstract

    Strontium-90 was determined in samples from all over the country of precipitation, stream water, lake water, ground water, drinking water, sea water, dried 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. Cesium-137 was determined in air, precipitation, sea water, sediment, 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 1985 are given. Tritium was determined in precipitation, stream water, lake water, drinking water, ground water and sea water. Technetium-99 and 210Po 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 Barsebåck and Ringhals were monitored for 137Cs and corrosion products (58Co, 60Co, 65Zn, 54Mn).
