Description
Objective: To estimate the exposed dose levels of 2 two victims, who died one month after they were accidentally irradiated by Cobalt-60. Methods: Three teeth were extracted from 2 victims. The signal intensities of separated enamel samples were measured with ESR spectrometer. The accumulated exposed doses were reconstructed according to a calibration curve established using Cobalt-60 γ-rays. Results: A calibration curve between signal intensity and exposed dose was established. The estimated doses of 3 teeth were 26.1 ∼ 29.4 Gy, for victim A, 14.9 ∼ 18.3 Gy and 15.2 ∼ 18.5 Gy for victim B. The doses are close to the result of the other Laboratory. Conclusion: The application of ESR dosimetry in human tooth enamel could provide important information for a dose estimation of victims exposed to heavy doses of radiation. (authors)
