The retrospective dosimetry is a part of dose reconstruction for estimation of exposed dose occurred years before the estimation. As a biosample, tooth enamel is known as to show good sensitivity to the absorbed dose and is widely used. Since the later 1980s, EPR dosimetry with tooth enamel has been studied and applied for the retrospective dosimetry. There are some factors affecting the sensitivity of enamel to absorbed dose. One of the factors is a size of enamel. Grain size of the 1.0 mm -0.1 mm range is commonly used and 0.60 mm ~ 0.25 mm is recommended in other study. But the sensitivity can be varied by the grain size. In this study, the granular effect of enamel to the sensitivity of EPR spectrum is examined. To verify the effect, 15 teeth were used for the enamel separation. In the enamel separation, to minimize the physically induced EPR spectrum, only chemical separation method was use...Read More
