Abstract
The aim of this study is to explore the thermoluminescence properties of beta irradiated natural quartz annealed at 900â¯Â°C, that is, beyond its second phase inversion temperature of 867â¯Â°C. The sample was annealed to improve its sensitivity and to deplete any residual charge from electron traps. The glow-curve corresponding to 10â¯Gy shows three peaks when measured at 1â¯Â°C/s; a dominant one at 71â¯Â°C, the subject of this report, and two other ones at 125 and 177â¯Â°C. The dose response of the main peak was studied in the range 1-300â¯Gy. The activation energy of the main glow-peak was evaluated as ~1â¯eV. Kinetic analyses using various methods show that the main glow-peak follows first order kinetics.
