Abstract

A method for measuring archaeological dose of Packjae pottery shards using thermoluminescence dosimetry(TLD) has been studied. TL measurement has been achieved using quartz crystals in the size range of 90 to $125{\mu}m$ diameter extracted from the pottery shards. The stable temperature region of the TL glow curve which is devoid of anomalous fading components was identified by the plateau test and found to exist from 265 to $300^{\circ}C$. The archaeological dose of the pottery shards was estimated to be 7.43 Gy using the dose calibration curves obtained from sequential irradiation of $^{137}Cs$ gamma source to the samples and TL measurement of natural samples.

TL 연대측정법을 이용하여 백제 토기 시편의 고고학적 선량 분석방법을 확립하였다. TL 측정을 위한 시료는 토기 시편으로부터 $90{\sim}125{\mu}m$ 크기의 석영 결정만을 분리하여 준비하였다. TL 측정을 통하여 얻어진 글로우 곡선에 대한 plateau 평가 결과 $265{\sim}300^{\circ}C$ 영역에서 비정상적인 fading이 없는 안정된 TL이 방출됨을 확인하였다. 토기 시료에 축적된 자연 TL량과 감마선원인 $^{137}Cs$을 인위적으로 조사하여 얻어진 선량에 따른 TL량의 외삽을 통하여 시편의 선량을 결정하였다. 그 결과 백제 토기 시편에 축적된 고고학적 선량은 7.43 Gy이었다.
