摘要:Abstract The paper reports themoluminescence glow curve analysis of \{UV\} (ultraviolet), β (beta) and γ (gamma) induced limestone collected from Amarnath holy cave. The collected natural sample was characterized by X-ray diffraction (XRD) technique and crystallite size calculated by Scherer's formula. Surface morphology and particle size was calculated by transmission electron microscopy (TEM) study. Effect of annealing temperature on collected lime stone examined by \{TL\} glow curve study. The limestone was irradiated by \{UV\} radiation (254 nm source) and the \{TL\} glow curve recorded for different \{UV\} exposure time. For beta irradiation Sr90 source was used and is shows intense peak at 256 °C with a shoulder peak at higher temperature range. For gamma radiation Co60 source and \{TL\} glow curve recorded for different doses of gamma. The kinetic parameters calculation was performed for different glow curve by computerized glow curve deconvolution (CGCD) technique. The chemical composition of natural limestone was analyzed by energy dispersive X-ray spectroscopy (EDXS).
