Abstract

This paper reports TL glow curve analysis and evaluation of kinetic parameter for Amarnath stone collected from Amarnath Holy Cave. TL was recorded with different heating rates (3.3, 4, 6.7, 8, and 10 ° s−1). The samples gave good TL peaks at 310, 314, 308, 323, and 327 °C for the different heating rates. The corresponding activation energy (E) values were calculated. The peaks were indicative of second-order kinetics. Samples were characterized by XRD analysis. Inductively coupled plasma activated emission spectroscopic (ICP–AES) analysis was performed to determine percentages of elements in the natural mineral. Results from ICP–AES and XRF (X-ray fluorescence spectroscopy) studies were compared.
