Abstract:

Thermoluminescence in the main dosimetric peak at 450 K in the 2.4-, 3.0- and 3.8-eV emission bands of the TLD-500 detectors has been studied. The thermoluminescent (TL) curves, which are obtained at the doses Δ D = 10- 5 - 1 Gy, are approximated by the general-order kinetics equation. A compensation relation between the activation energy and the effective frequency factor is observed for all the bands. The compensation relation parameters-the isokinetic temperature Ti and the constant s0-are estimated. Possible applications of the said quantities in practical luminescent dosimetry are noted. It is concluded that the compensation effect influences the kinetics of TL processes in the TLD-500 dosimetric crystals. © 2007 Elsevier Ltd. All rights reserved.
