This study investigates the luminescence characteristics of quartz samples irradiated with a 60Co gamma source across a dose range of 57 to 570 Gy. Prior to irradiation, the samples were annealed at 650°C for two hours. The thermoluminescence (TL) spectra were measured at a heating rate of 5°C/sec, revealing two primary peaks at approximately 200°C and 320°C. The intermediate peak displayed a shoulder around 150°C. It was observed that the peak temperature maximum (Tm) at 206±2°C remained constant regardless of the irradiation dose. The intensity of the intermediate peak decreased significantly over time, with a lifetime estimated at 8±2 days for most doses and 19±2 days for the highest dose (570 Gy). Dose-response studies showed a linear relationship between the TL intensity and the irradiation dose up to 600 Gy. Comparisons with natural quartz samples indicated significant differences in glow curve shapes and sensitivities. Computerized glow curve deconvolution (CGCD) methods confirmed that the annealed quartz glow curve could be described as a superposition of four first-order kinetic peaks. These findings provide important insights into the stability and behavior of TL signals in quartz, which are crucial for applications in radiation dosimetry and archaeological dating.
