Nanocrystalline boehmite material was synthesized using the hydrothermal method. Different annealing temperatures have been used to transform boehmite into different alumina phases to study the effect of different phase transitions on the thermoluminescence properties of alumina. XRD analysis was carried out to investigate the crystal structure of the different alumina phases. The thermoluminescence glow curves for different alumina phases showed different structures; however, the sensitivity was almost constant for all the phase transitions of alumina over the applied dose ranging from 0.55 to 330 Gy.

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

The current work was going to study the dosimetric properties of Egyptian muscovite minerals irradiated with β‐rays using the thermoluminescence technique (TL). The analysis of the TL glow curves was done using the (Tm − Tstop) and the initial rise methods. The deconvolution of the muscovite glow curves was analyzed to have eight superimposed trapping peaks. These trapes were located at 0.72, 0.80, 0.98, 1.09, 1.19, 1.30, 1.50, and 1.59 eV. Muscovite samples were studied at doses up to 330 Gy and exhibited good linearity in relation to beta radiation. The kinetic parameters, sensitivity, and dosimetric characteristics were evaluated. High accuracy was achieved through the repeatability of TL measurements.
