초록
발아억제 선량범위인 0.15 kGy와 0.30 kGy의 감마선과 전자선이 조사된 감자와 마늘을 대상으로 thermoluminescence (TL) 측정에 의해 방사선 조사유무를 확인하였다. 감자와 마늘로부터mineral을 추출하여 TL 측정을 함으로써 방사선 조사선량과 TL intensity 간의 높은 상관관계를 확인하였다. 방사선 조사되지 않은 시료들은 특이한 TL glowcurve를 나타내지 않았으나 방사선 조사된 시료들은
Potato and garlic irradiated with gamma ray and electron beam at sprout-inhibition doses, 0.15 and 0.30 kGy were subjected to the detection whether they are irradiated or not by measuring thermoluminescence(TL) for the minerals adhering to the samples. Minerals extracted from the samples showed a high correlation coefficients between absorbed doses and corresponding TL responses. Nonirradiated samples, however, did not exhibit characteristic TL glowcurves. Major glowcurve peaks were observed at 200 to
