Differences in the Radiation Sensitivity of Human Tooth Enamel in an Individual and among the Individuals in Dental ESR Dosimetry

To study the individual difference of radiation sensitivity of tooth enamel in dental ESR dosimetry, 144 enamel samples were separated from 5 subjects, irradiated with 60Co gammarays up to 1290×10-4C/kg (500 R), and measured with the ESR system. The coefficient of variation of ESR signals obtained f...

Summary:To study the individual difference of radiation sensitivity of tooth enamel in dental ESR dosimetry, 144 enamel samples were separated from 5 subjects, irradiated with 60Co gammarays up to 1290×10-4C/kg (500 R), and measured with the ESR system. The coefficient of variation of ESR signals obtained for all enamel samples except two samples from one tooth was 7.8%.
