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

Name: Work Video:
Duration: 3 min 30 s
Description: 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%.
