内容記述 | The Δ^<14>C concentration in the collagen of human teeth was retrospectively investigated to elucidate the relationship between the number of nuclear weapon tests and the distribution of Δ^<14>C concentration in teeth. Teeth were extracted for dental therapy from July 1987 to February 1991 from patients who were residents of Aichi prefecture, Japan. Tooth collagen was extracted with HCl and converted to amorphous carbon by heating in a vacuum line. Specimens for Δ^<14>C analysis were prepared by mixing the amorphous carbon with silver powder. The Δ^<14>C concentration was measured by a Tandetron accelerator mass spectrometer. The distribution was analyzed in detaile by separating the third molar from other teeth. Two peaks were observed in both the third molar and other teeth. The shape of peaks of the third molar was broader than that of other teeth. These two peaks correspond to the peaks of the number of nuclear weapon tests in 1958 and 1962. The first peak year and the second peak year of other teeth fall behind by 3 to 4 years those peaks of the number of nuclear tests, respectively. the Δ^<14>C concentration in human teeth collagen makes clear two peaks corresponding to the number of the nuclear weapon tests. | |||||
