Strontium-90, radiocesium, and other radionuclides were deter mined in samples from all over the country of air, precipitation, stream water, lake water, ground water, drinking water, sea water, soil, sediments, dried milk, fresh milk, meat, fish, cheese, eggs, grain, bread, potatoes, vegetables, fruit, grass, moss, lichen, sea plants, total diet, and humans. Estimates are given of the mean contents of radiostrontium and radiocesium in the human diet in Denmark during 198S and 1989. Tritium was determined in precipita tion, ground water, other fresh waters, and sea water. The -/-background was measured regularly by TLD's and a Nal detector. The marine environments at Barseback and Ringhals were monitored for t3/Cs and corrosion products (5«Co,«>Co,MZn,WMn). During 1988 and 1989 the expanded programme initiated after the Cherno byl accident in 1986 was brought back to the pre-Chernobyl level.
