Strontium-90 in shed deciduous teeth collected in Denmark, the Faraoes and Greenland from children born in 1950-1958
Shed deciduous teeth were collected in 1962-1965 from 25 schools in Denmark, the Faroes and Greenland. Approx. 10,000 teeth from children born in the period 1950-1958 are included in the present investigation, which compiles 215 90Sr analyses. The 90Sr level in deciduous teeth crowns increased by a factor of four from 1953 to 1958.
Faroese teeth contained nearly 4 times as much 90Sr as teeth from Denmark and Greenland. Incisors contained approx. three fourths of the level found in second molars. The 90Sr diet levels measured in 1962-1966 in Denmark, the Faroes and Greenland showed a similar variation between locations as the 90Sr in deciduous teeth from children born in 1950-1958 in the same areas.
The 90Sr mean level in shed deciduous teeth is considered as an estimate of the 90Sr content in the tooth donors bone when he was 1 year old. (C)1968Health Physics Society
