This method is based on the formation of paramagnetic centers due to the ionization. The electron is captured by carbonate anions that appear as hydroxyapatite crystal lattice defects. The probability of formation of radiation-induced defects is proportional to the carbonate impurity concentration and, therefore, determines the enamel radiation sensitivity. The concentration of carbonate anions depends on the content of micro- and macronutrients in water and food, so the enamel radiation sensitivity may differ for people living in different geochemical conditions, as well as in areas with different anthropogenic pollution. The present study aims to investigate the uncertainty of the EPR dosimetry associated with the calibration of the EPR signal. The tooth enamel radiation sensitivity of the Ural residents was studied. It was found that the enamel radiation sensitivity for ...
