Abstract
Since the radioactivity of U was discovered by Becquerel in 1896, a number of radiometric dating techniques based on radioactive decay have been developed with the help of precise and accurate instruments. Among them, radiocarbon dating was introduced as the most effective method in archeology in Korea. However, though the radiocarbon methods have contributed greatly to the development of archeology in Korea, it is limited to organics in a matrix of soil and sediment, including organic carbon, charcoal, bone and so on. If there are no organics in some paleolitic sites, other methods are required for dating. Therefore, we introduced OSL (Optically Stimulated Luminescence) dating method in this paper. The method is mainly based on quartz grains or other particles. The aim of this paper is to discuss about sampling method and the limitation of its application in archeology.
1896년 Becquerel에 의해 우라늄의 방사능이 발견된 후, 방사붕괴 원리를 이용한 수많은 연대측정법이 개발되었고, 분석기기도 정밀화되면서 그 정확도도 날로 높아지고 있다. 방사성동위원소 연대측정법 중에서
