Title: Radium-226 and Lead-210 in Human Teeth and Bones
Abstract: This is the report of a study on the suitability of using measurements of certain isotopes in tooth to estimate levels of the same isotopes in bone. Human tooth, jaw, tibia shaft, calvarium, femur head, and rib from thirteen autopsies were analyzed for 226Ra, 210Pb and stable calcium. The degree of uniformity among subjects of the tooth-bone ratio for each type of bone was examined by rank-difference correlation. The calculated coefficients were consistent with the existence of a high positive correlation between tooth and bone burdens of the isotopes measured. Regression analysis using our data as a calibration set led to the prediction that in future sampling when tooth is measured at or above the presently reported mean level for 226Ra, the mean bone value will lie within approximately ±50% of the tooth value at the 95% confidence level. Lead-210 level predicted for bone is subject to larger error and is more dependent on the bone type to which the tooth level is referred.
