European standards DIN EN 13751 | DIN EN 1788
Food stuff often is irradiated with ionizing radiation for sterilisation purposes. This requires the detection and estimates of the applied doses. The attached mineral dust or the food itself serves as dosimeter.
TL/OSL to detect irradiation of e.g. spices
Presence/absence of signal specific features shows the irradiation
Dose estimates are possible for some materials
Jo, Y., Sanyal, B., Chung, N., Lee, H.-G., Park, Y., Park, H.-J., and Kwon, J.-H. (2015). Calibrated photostimulated luminescence is an effective approach to identify irradiated orange during storage. Radiation Physics and Chemistry 111, 81-86.
Photo Stimulated Luminescence (PSL)
Silicate minerals contained in food according EN 13751
Spices (dust attached to spices)
Shrimps (intestines contain dust/sand)
Shells (crushed)
Thermoluminescence (TL)
Silicate minerals extracted from food according to EN 1788
Herbs (dust attached to herbs)
Seafood
For a detection of food irradiation with luminescence methods (EN1788, EN13751) the food has to be irradiated in the laboratory for comparison. The large doses required are achieved with the Xray Dose irradiator.
