? The thermoluminescence （TL） from anhydrous magnesium sulphate irradiated with γ-rays was measured in pure nitrogen environment from room temperature up to 500℃ The TL glow curves were deconvoluted into four elementary peaks based on the Gaussian function The trapping parameters including activation energy

frequency factor and kinetics order were determined for each peak by two heating rates and variable heating rate methods The results show that the total glow curve can be well fitted with general order kinetics
