초록
각종 가공식품 원료로 사용되고 있는 건조 채소류 중 표고버섯, 시금치, 무청, 미나리, 무, 호박 등 6종에 대하여 1, 4, 7 kGy의 선량으로 감마선을 조사하고, photostimulated luminescence (PSL)와 thermoluminescence (TL) 등 물리적 분석방법을 이용하여 감마선 조사 여부를 확인하였다. PSL 측정에서 비조사 표고버섯, 시금치, 무청, 미나리, 무 및 호박에서는 각각 194.0±223.4, 695.5±26.2, 598.0±4.2, 266.5±9.2, 503.0±190.9 및 270.5±245.4 수준의 photon count가 측정되어 비조사 시료의 범위(700 이하의 값)에 속하였으며, 1 kGy 이상 조사군에서는 모두 방사선 조사시료의 범위인 5000 이상의 photon count를 나타내었다. 또한 6종의 시료에 대해 TL 분석을 실시한 결과, 비조사군의 TL ratio (TL1/TL2)는 0.021 이하를, 1 kGy 이상 조사군에서는 0.653 이상으로 나타나 본 연구에 사용된 6종의 건조 채소류는 PSL과 TL 분석에 의해 조사여부의 검지가 가능한 것으로 확인되었다.
Abstract
Photostimulated luminescence (PSL) and thermoluminescence (TL) were analyzed for dried vegetables irradiated at 0, 1, 4 and 7 kGy, such as dried oak mushroom, spinach, radish leaves, water cress, radish, and pumpkin, to detect irradiation treatment. PSL results that photon counts for non-irradiated samples were lower than 700 that corresponds to negative, while those of irradiated samples over 1 kGy showed positive photon counts(≥5000), indicating irradiation treatment. Meantime, TL ratio by normalization was lower than 0.021 in threshold value for non-irradiated samples and more than 0.653 for irradiated samples, and therefore it was possible to detect whether the 6 kinds of dried vegetables were irradiated or not by analyzing PSL and TL.
