The thermoluminescence kinetic parameters of MgSO4:Cu microcrystalline was obtained by various methods. These parameters are kinetic order (b), activation energy (E) and frequency factor (s). Deconvolution, Isothermal decay, Various heating rate and Initial rise are the methods that were used in this survey. For obtaining kinetic order of each peak, Deconvolution and Isothermal decay methods were used. In Deconvolution method Im, Tm and number of peaks are the input of the program, the first and second was determined by the shape of each peak, the third was obtained by Tm-Tstop method. Three different methods: Deconvolution, various heating rate and Initial rise was applied to calculate activation energies. Frequency factor or probability of escape for each peak was calculate by Various heating rate method.
