Peak 5 in the glow curve of TLD-100 (at a temperature of approximately 200°C) was studied as a function of post-irradiation annealing at 165°C. Computerized glow peak analysis shows that the order of kinetics of peak 5 increases from 1.2 ± 0.05 (1 SD) following 165°C annealing for five minutes to 1.72 ± 0.07 (1 SD) following annealing at 165°C for thirty minutes. Extrapolation of the results to zero annealing time yields a value of kinetic order consistent with unity. The glow curve analysis also indicates that peak 4 (the satellite peak at approximately 175°C) is undetectable even at the lowest annealing duration of 5 minutes. The high temperature satellite of peak 5 (peak 6 at approximately 225°C) grows with increasing annealing time to 10% of the intensity of peak 5 after annealing for 30 min. Glow curve analysis including peak 6, however, does not significantly change the conclusions regarding the increase in the order of kinetics of peak 5 as a function of annealing time or the consistency of the extrapolated results with kinetic order unity at zero annealing time. Analysis of isothermal decay curves at 165°C shows that the relative intensity of peak 4 to peak 5 decreases with increasing annealing time, from 8% after 5 min annealing to 0.5% after 30 min annealing.
