CONTENTO DE STRONTIUM-90 IN DENTES DECIDUE DE JUVENILES.—Le contento de strontium-90 del coronas de dentes decidue de juveniles nate inter 1950 e 1958 es adequatemente describite per le equation CT = KCd ubi CT es le Sr90 del corona dental e Cd le Sr90 del lacte. Pro incisores e cuspides intacte e prime e secunde molares cariose, le pendentia K es 0,59, 0,76, 0,69, e 0,77, respectivemente. Le equation predice nivellos de inter 12 e 16 pC Sr90/gm Ca in incisores e secunde molares pro juveniles nate durante le anno 1963 quando le concentration medie de Sr90 in le lacte attingeva un nivello maximal de 21 pC Sr90/gm Ca in St. Louis, Missouri, U.S.A.
