Detection of baby food sterilized with ionizing radiation using thermoluminescence

Abstract Food sterilization with ionizing radiation is a well-established technology, which constantly extending to several products due its numerous advantages. However, radiosterilization prohibited food categories, such as baby since it could cause nutrient degradation of foods significant effects on the infants’ health. As result, any governmental agency responsible for detection irradiated should first focus consumed by babies/children. To this respect, present work explores whether TL can be employed method post-sterilization dosimetry food, studying properties their glass containers they would equally and jointly exposed during process. Two different reputable brands, i.e., Hipp ® Nestle , are used purpose. Both exhibit linear dose response doses up 3 kGy, while no sensitization main peaks observed. Though behavior not very stable time (strong fading) yet fading correction possible. Dose recovery tests were successfully conducted, calculating administered high accuracy. A computerized curve deconvolution analysis (CCDA) was also performed revealing that all glow curves fitted one peak continuous trap distribution three discrete-energy peaks, demonstrate over range 50–3000 Gy. Thus, findings promising towards through containers.
