Abstract
A series of experiments is performed to measure radon concentration in the near-surface soil gas at the four locations (Cheju-Si, Seoguipo-Si, Taejeong-eup, Seongsan-eup) in Cheju Island, using CR-39 detectors placed inside radon cups. Two types of radon cups are installed in shallow holes of about 15 cm in diameter and 50cm in depth. The optimum etching conditions, i.e., the concentration of NaOH solution, etchant temperature and etching time, are found to be 625N,
CR-39 검출기를 부착한 두 종류의 라돈컵을 사용하여 토양중의 라돈 농도를 제주도 일원의 4개지역(제주시, 서귀포시, 대정읍, 성산읍)에서 측정하였다. 본 실험에서는 CR-39 검출기의 최적 부식조건을
