Strontium-90 content was measured by means of Cerenkov radiation in deciduous teeth collected in three areas in northern Finland from children born in 1952 to 1964. The /sup 90/Sr levels in tooth crowns in areas I and II showed a continuous increase in children born in 1952 to 1958, no further increase during the years 1959 to 1961, a sharp increase in 1962 to 1963, and no further change in 1964. In the northernmost part of Finland (area III) the /sup 90/Sr contents of deciduous teeth when ploited against year of birth showed a slightly different trend with no increase during the years 1952 to 1957 and a steep rise in 1958 and 1959. These changes occurred in both Lapp and non-Lapp children. These differences in the /sup 90/Sr content of deciduous teeth were presumably related to environmenial peculiarities and specific dietary habits in area III. The maximum /sup 90/Sr level, 16.76 pCi/gCa, was found in a sample of tooth roots of four Skolt children born in 1963. The /sup 90/Sr contents in the crowns of the four types of deciduous teeth were related as follows: second molars> cuspids> first molars> incisors. (auth)
