Environmental radioactivity in Denmark in 1988 and 1989

Strontium-90, radiocesium, and other radionuclides were determined 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 precipitation, ground water, other fresh waters, and sea water. The y-background was measured regularly by TLD's and a NaI detector. The marine environments at Barseback and Ringhals were monitored for ¹³⁷Cs and corrosion products (⁵⁸Co, ⁶⁰Co, ⁶⁵Zn, ⁵⁴Mn).
During 1988 and 1989 the expanded programme initiated after the Chernobyl accident in 1986 was brought back to the pre-Chernobyl level.
