Photostimulated luminescence (PSL) and thermoluminescence (TL) analyses wereapplied to identify the cookie molds mixed with 2 mg of 10 kGy-irradiated minerals according tocookie processing methods and sonication time (0~60 min) for mineral separation. PSL analysisshowed that photon counts of cookies, dried or baked, ranged intermediate levels between thelower and upper threshold (700~5,000 counts/60 s), thereby showing its unsuitablility for screeningof irradiated cookie. The TL glow curve intensities, measured according to mineral separationtime (5, 10, 20, 40 and 60 mins) from the cookies using a sonicator, were high enough to identifyirradiation status and significantly increased with the time in dried cookies. Those of baked cookies,however, were relatively low and not linearly increased with the time, but still possible to identifythem (p⁄0.05).
