Environmental radioactivity in Denmark 1990 and 1991

Strontium-90, radiocesium, and other radionuclides were determined in samples from all over the country of air, precipitation, stream water, lake 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 1990 and 1991. Tritium was determined in precipitation, fresh waters, and sea water. The γ-background was measured regularly by TLD's and a NaI detector. Tc-99 determinations were carried out on various marine samples, first of all sea water. (au) (164 tabs., 76 ills., 23 refs.)
