Dose distribution in the oral region of a subject treated by radiation therapy for cancer of the epipharynx was determined retrospectively by ESR measurements of 38 tooth enamel samples using a calibration curve prepared previously. The result is considered to agree well with the prescribed doses. Doses to ten of the above samples were determined by the additive re-irradiation method as well as the calibration curve method. Both methods yielded almost identical dose values in the range of 3 to 20Gy.
