초록
In this study, we investigated the applicability of the photostimulated luminescence(PSL), thermoluminescence (TL) and electron spin resonance (ESR) methods for various foods. The analysed samples consist of 11 items including dried fruits (6 items) and mushrooms (5 items). To compare between non-irradiated and irradiated food, all samples were irradiated with 60Cogamma-ray source. In PSL study, the photon counts of all the unirradiated sample were identifiednegative (lower than 700). The photon counts irradiated (1, 5, 10 kGy) dried date-palm, dried jujubeand mushrooms (Auricularia auricula, Phellinus linteus and Sarcodon aspratus) showed positive(higher than 5,000) and the results for the other samples were negative or intermediate (¤700 and¤5,000). In TL analysis most of items can be applicable to detect irradiated foods because ofshowing TL ratio above 0.1. The glow curves by TL method were estimated in the range of 150~250C in irradiated samples. In ESR measurements, the intensity of ESR signal (single-line)increased as the dose of irradiation increased. In particular, the specific ESR signals of irradiationinducedradical were detected in dried papaya, dried date-palm, dried banana, dried pineappleand S. aspratus. According to the results, PSL, TL and ESR methods were successfully applied to detect the irradiated foods. It is concluded that PSL, TL and ESR methods are suitable for detectionof irradiated samples and a combined method is recommendable for enhancing the reliabilityof detection results.
