건조 채소류 중 건조 양파 및 마늘에 대하여 감마선 조사(1,4,7kGy)에 따른 검지특성을 photostimulated luminescence(PSL), thermoluminescence(TL) 및 electron spin resonance (ESR)분석에 의해 확인하였다. PSL분석 결과, 건조 양파 시료는 설정된 negative 및 Positive 기준에 맞게 비조사군과 조사군의 차이를 쉽게 확인할 수 있었다. 그러나 건조 마늘의 경우 1

The identification characteristics of inadiated dried onion and garlic at 1, 4 and 7 kGy were investigated by analyzing their photostimulated luminescence (PSL), thermoluminescence (TL) and electron spin resonance (ESR). The PSL results showed that the photon counts of non-irradiated dried onion were less than 700 (negative) and those of irradiated samples at 1kGy or more were over 5000 (positive), making it possible to discriminate non-irradiated onions from irradiated ones. However, the intermediate counts (700-5000) were observed in irradiated garlic at 1 and 4 kGy, even though positive counts were measured in 7 kGy group. Radiation-induced TL glow curves were measured at range in both irradiated onion and garlic samples at 1 kGy or more, which could identify irradiated groups. Furthermore, determination of TL ratios for both samples could verify the above results. It was found, however, that ESR spectroscopy was not suitable for the detection of irradiated dried onion and garlic.
