Abstract

Abstract: Radioluminecscence (RL), the light emitted from a material immediately upon ionizing radiation, has been used to detect the dose rate. On the other hand, thermoluminescence (TL) and optically stimulated luminescence (OSL) by the stimulation with the heat and light after irradiation have been used to find out the cumulated radiation dose. Because it was considered as effective to handle these three phenomena in integration to estimate the energy band structure of the material precisely, an algorithm for calculating the glow rapidly and consistently was developed in this study when three types of stimulations including irradiation are applied concurrently or sequentially. The deconvolution using this algorithm can decide the properties contained in the material more precisely because the glows from different stimulations are related frequently to the different aspects of the properties. The computer program to realize the deconvolution by means of these schemes was also developed and it was applied to the glow curves of RL and OSL from Al2 O3 :C to evaluate the efficiency of the developed algorithm. Highlights: RL, TL and OSL glow curve deconvolution employing interacting model. Simulation both irradiation and TL/OSL readout stages for various dose level. Application in the identification OSL kinetics of Al2 O3 :C.
