A new method to analyze the thermoluminescence, (TL) glow curve has been presented. It has been shown that this method is efficient and fast in generating the TL glow curves and can be adopted in a numerical curve fitting for obtaining the relevant TL parameters of a given TL glow curve data. This new method is based on a general approximation (GA) which assumes only that the concentration of the electrons in the conduction band is negligible when compared with the concentration of the electrons in the traps. The GA method has been tested against the reference glow curve data which was generated by the full iteration method without any prior approximation in the one-trap-one-recombination-centre model. By finding the best fit between the reference data and the curves generated by the GA method, the values of the kinetics parameters have been determined, Also, the general order kinetics (GOK) and the peak shape method have been examined. The fitted values of the activation energy and the initial concentration of electron by the GA method match reasonably well with the original value.
