“…Studies of the effects of heat treatment [8] and irradiation with different Ultraviolet (UV), beta and gamma sources on the TL response were also performed on limestones [9,10]. Determination of the kinetic parameters of the traps responsible for the TL peaks and studies on TL peaks deconvolution were carried out to understand the stability of the centers of samples used for luminescence dating, which is very important, since in dating, the sample must have stable peaks that remain for a few hundred up to million years [11][12][13] Calcite samples taken from caves, shells and limestone samples have also been successfully dated by TL in several other studies in the last decades [14][15][16][17][18] which emphasizes its role in the area.…”

The study presents TL and OSL characterization of orange calcite. It is known that calcite exhibits TL however its OSL emission is unwell studied. The morphological characterization was done by means of X-rays diffraction (XRD) technique and it was confirmed that the sample is a pure calcium carbonate. Total and traces elements were determined using Total Reflection X-Ray Fluorescence (TXRF) technique and several impurities were found as P (53070 mg/kg), S (877 mg/kg), K (442.1 mg/kg), Ca (118290 mg/kg), Fe (330.4 mg/kg), Cr (101.19 mg/kg), and Ni (115.01 mg/kg), also some trace impurities, as Cu (1.96 mg/kg) and Zn (1.30 mg/kg), Mn (57.21 mg/kg) were determined and they may have important role in the luminescent emission. Sample in powder form was irradiated with crescent doses of beta particles, in an interval of 5–25 Gy and showed TL peaks at approximately 93, 125, 162, 189 and 227 °C. An OSL response was verified and can be fitted using 3 components with decay constant values of 2.3, 10.0 and 77.4 s.

“…Thermoluminescence (TL) dosimetry is considered one of the most used techniques for studying the interaction of radiation with the matter for various applications [1]. Although numerous natural materials [2][3][4][5][6] are employed in thermoluminescence dosimetry, developing and synthesizing novel materials remains an ongoing research topic [7][8][9].…”

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.

“…Based on radiation induced free radicals, Egyptian limestone was used as an effective and low-cost electron paramagnetic resonance (EPR) gamma dosimeter [21]. Thermoluminescence characteristics of sedimentary natural calcite in Gebel El Galala, Egypt, revealed an average TL sensitivity of 322.356 Gy −1 mg −1 with minimum detectable dosage of 976.221 µGy and a wide range of linearity, from 1.1 to 330 Gy in response to beta particle irradiation [22]. For the sake of retrospective dosimetry, thermoluminescence properties of natural tuff were investigated in the dose range 0.5-5 Gy, where linear doseresponse is obtained [23].…”

Thermoluminescence characteristics of natural rhyolite have been studied. Dose response at a wide dose range of 0.5–2000 Gy has been determined. Minimum detectable dose and thermal fading rate are evaluated. Glow curve deconvolution is conducted after determining the best read-out conditions. The repeated initial rise (RIR) method is used to detect the overlapping peaks, and a glow curve deconvolution procedure is used to extract the thermoluminescence parameters of rhyolite. According to the findings, rhyolite glow curves show five interfering peaks corresponding to five electron trap levels at 142, 176, 221, 298, and 355 °C, respectively, at a heating rate of 3 °C/s. The obtained kinetic order for the deconvoluted peaks showed mixed-order kinetic. The reported results might be useful to introduce rhyolite as a natural sustainable material for radiation dosimetry applications.
