The TL parameters such as activation energy, order of kinetic, geometrical symmetry factor and pre-exponential frequency factor were investigated from the glow peak by Peak Shape (PS) method and Computerized Glow Curve Deconvolution (CGCD) technique. Within the heating rate 2–10 K/s only a low temperature distinct peak was observed in the temperature range 348–357 K. Natural TL of muscovite was checked, but no significant TL was observed within 298–520 K in any heating rate. The thermoluminescence (TL) glow curves of X-ray irradiated micro-grain natural muscovite were recorded within 298–520 K at various linear heating rates (2 K/s, 4 K/s, 6 K/s, 8 K/s and 10 K/s).
