Abstract:Chicken and fish have been investigated for the detection of radiation treatment using thermoluminescence (TL) technique. The samples were irradiated by 60Co gamma-source at the absorbed doses of 1, 2, 3, 4 and 5 kGy. TL response of treated and untreated samples in the temperature range of 50–300 °C was measured using TL reader with a temperature profile of 10 °C/s. The results revealed that TL values increased with temperature and maximum signal were obtained at 195 °C, in each case. It was also observed that the TL intensities enhanced with the absorbed doses (1–5 kGy) and the increase was dependent on the absorbed dose. From this study it is concluded that the TL technique is a rapid, simple and promising method for identifying chicken and fish treated with gamma-irradiation.
