Study of the thermoluminescence kinetic parameters of a β-irradiated natural calcite

Abstract The current study was going to investigate the thermoluminescence properties of brownish calcite of sedimentary origin in Gebel El Galala, Egypt. The analytical characteristics of the calcite samples were performed using XRD and atomic spectroscopy techniques. The samples were irradiated to different doses of beta particles from 0.11 Gy up to 330 Gy. The TL glow curves of the samples were deconvoluted using new TL software. The deconvolution indicated the presence of 6 overlapping glow peaks. The kinetic parameters were obtained using different methods and their results were in a good agreement with each other. The samples exhibited sensitivity in average of 322.356 Gy−1 mg−1 and a minimum detectable dose of 976.221 μGy. The samples exhibited a long range of linearity from 1.1 up to 330 Gy responding to beta particles irradiation. The fading results recommended to start the measurements of the calcite samples after 2 days to give established measurements.
