英文摘要	The current work was going to study the TL properties of natural milky quartz mineral associated with tintungsten-fluorite mineralization in the Eastern Desert of Egypt. The chemical compositions of the investigated samples were examined by Atomic Absorption Spectrometer. The samples were irradiated to different gamma doses from 250 mGy up to 2 kGy. The kinetic analysis of the glow curve was carried out and it revealed that there were composed of six trapping sites at energies 0.92, 0.99, 1.08, 1.22, 1.32 and 1.48 eV responsible for deconvoluted glow peaks at 417.1, 433.9, 474.1, 532.1, 571.8 and 641.7 K respectively. The TL response exhibited a linear behavior in the range from 5 Gy up to 500 Gy and supralinear attitude in the range 500 Gy up to 2 kGy. The minimum detectable dose of the investigated samples was evaluated as 627 mu Gy and the sensitivity was measured to be 293.27 Gy(-1) mg(-1). For the fading results, the TL-intensity of the samples was decreased to be 55% from its original value in five days and after then no change in the intensity was observed up to two months.
