摘要：

In the present paper we have investigated sensitization of the 220 degrees C TL peak in quartz, separated from sand, as a function of pre-gamma dose and post-irradiation annealing treatment at a test gamma dose of 50 Gy. A pre-gamma dose of 2.50 kGy followed by 400 degrees C post-irradiation annealing treatment yielded the maximum sensitization factor of 35. The sensitization decreases for pre-doses higher than 2.50 kGy as well as for post-irradiation annealing temperatures higher than 400 degrees C. The sensitization of the peak in quartz due to accrued geological dose of 72 Gy and thermal annealing treatment was estimated to be 2.36. The position and shape of the TL glow curve in sensitized and unsensitized samples was nearly the same. (C) 1997 Elsevier Science Ltd.
