title: [Content of thorium isotopes in human teeth].
abstract: The concentrations of Th isotopes were determined in the teeth of persons belonging to 3 age groups (under 7,8-16, over 16) from 10 areas of RSFSR. Differences in the content of 228Th and 232Th in the teeth of persons of various ages living in different areas of the RSFSR are statistically insignificant. There is no balance between them in all the samples. The ratio of their concentrations is on an average 2.4 +/- 0.9. The Th isotope summary irradiation dose absorbed by the osseous tissue is 9.6 X 10(-6) Gy/year.
