Abstract
The current work is aimed to study the thermoluminescence (TL) properties of natural milky quartz associated with Metamorphic Rocks extracted from the Eastern Desert of Egypt. Atomic absorption spectrometer was used to assess the chemical compositions of the samples, and X-ray diffraction was used to examine the structural properties (XRD). The deconvolution of the glow curve was carried out and revealed that there were ten trapping sites at 0.623, 0.936, 1.02, 1.06, 1.31, 1.47, 1.58, 1.76, 2.49, and 2.96 eV. The linearity of the sample was examined for each glow peak. The analysis of the glow curve was studied also by Tm − Tstop and various heating rates (VHR) giving the kinetics parameters (activation energy E, eV).The minimum detectable dose of the investigated samples was found to be 24 µGy. The dosimeter demonstrated a high level of repeatability. The fading signal was investigated for varying storage times up to 30 days.Graphical abstract
