Description
Glow curves of abundant quartz powder were obtained with the RGD-3B thermoluminescence (TL) reader. TL peaks with 448, 551, 654, 756 K were identified at the heating rate of 5 K/s. The activation energy, frequency factor and lifetime of trapped charge were evaluated at ambient temperature for four peaks by the method of various heating rates. Within a certain range of activation energy, the equivalent dose increases exponentially with the activation energy. The equivalent dose increases from 54 Gy to 485 Gy with the temperature from 548 K to 608 K, and it fluctuates around 531 Gy with the temperature from 608 K to 748 K. (authors)
