EPR and TL-based beta dosimetry measurements in various tooth components contaminated by 90Sr.
Radiat. Meas. 43, 813-818 (2008)
Thermoluminescence-based beta dosimetry, previously proposed for the estimate of the internal contamination in teeth, and EPR has been used in this paper to investigate the homogeneity of 90Sr contamination and of dose within nine teeth of one person born in the year of the onset of waterborne radioactive releases of the Mayak plutonium facility. A large deviation of dose and activity distributions in both enamel and radical dentine of the various teeth was observed. Average dose was View the MathML source in enamel and View the MathML source in radical dentine. Average 90Sr concentration was View the MathML source in enamel and View the MathML source in radical dentine. The observed deviation around the mean value of dose and 90Sr concentration can be explained due to the specific mineral evolution of each tooth at the time of Sr intake. In the same donor, a negative correlation was also observed between radical dentine and enamel for the 90Sr specific activity as well for the dose.
