title: Dental ESR dosimetry of a medical physicist who received occupational radiation exposure for almost 40 Y.
abstract: Dose distribution in the oral region of a medical physicist who received occupational radiation exposure for almost 40 y was determined retrospectively by electron spin resonance measurements of 24 tooth enamel samples using a calibration curve method. The result is considered to agree well with the value estimated from the record of his occupational exposure, including the measured values of personnel monitors. Doses to twelve of the above samples were determined by the additive re-irradiation method. The measured values obtained by the two methods agreed with the exception of one sample.
