The influence of heating rate on the TL response of the main glow peaks 5 and 4 + 5 of sensitized TLD-100 treated by two different annealing protocols

Abstract

In this study, the recently developed annealing protocol, which is based on the simultaneous application of UV (253.7 ± 1.2 nm) light and thermal annealing (300 °C for 30 min followed by 90 °C for 6 h), and the standard annealing protocol, which is based on 400 °C annealing for 1 h followed by 100 °C heating for 10 min were studied to obtain the sensitivity changes of the main dosimetric peak 5 and the summation of peaks 4 + 5 of sensitized TLD-100 dosimeter in 10 consecutive cycles after different heating rates between 1 and 50 °C/s. The results indicate that the heating rate highly influences the sensitivity of sensitized dosimeters and that the sensitivity change in the area of the main dosimetric peak 5 is generally higher than that of the summation of peaks 4 + 5 for the standard annealing protocol while it is less than that of the summation of peaks 4 + 5 for the newly developed annealing protocol at all the studied heating rates.
