“…Işınlama dozu ile sinyal şiddeti artışının orantılı olmamasının nedeni, her ölçümde numunelere yapışmış silikat minerallerinin miktarlarının ve/veya tiplerinin farklı olmasından kaynaklanmaktadır. Işınlanmış numunelerin yüksek OSL yoğunluklarına sahip olmasının nedeni, numuneye bağlı silikat minerallerinde bulunan elektron tuzaklarının fazlalığından kaynaklanmaktadır (Aygün vd., 2016;Yüce, 2021).…”

In this study, the potential of using OSL (Optically Stimulated Luminescence) reader for fast, easy and inexpensive detection of irradiated black cumin and poppy samples of different brands was investigated under blue light excitation. Three different brands were selected for each food from local markets and each brand of food was irradiated with Co-60 gamma radiation at doses of 1 kGy, 3 kGy, 5 kGy and 7 kGy. OSL signal intensities for each dose were measured both immediately after irradiation and one year after irradiation. While no OSL signal was observed in any of the non-irradiated samples, a significant increase in OSL signal intensities was observed in all samples after irradiation. In addition, it was determined that the OSL signal intensities obtained from some poppy and black seed brands were high enough to allow the determination of irradiation even one year after irradiation.
