“…The colour centres light abortion bands are different by the nature of the impurities found in the exposed sample. As it was previous shown in the literature [11], the magnitude of the "glass browning" effect can be corroborated to the magnitude of the dose absorbed in the glass sample. The "glass browning" can be reversed by applying of a thermal treatment to the used samples [12,13], making them reusable for other experiments.…”

“…Each type of ionizing radiation beams presents different interaction mechanisms when reaching an exposed material. In the case of the ionizing radiation sources having a homogenous 2πsr or 4πsr distribution, specialized detectors dose calibrations can be used by placing them in very well determined positions, simultaneous to the glass samples needed to be calibrated [11]. In the case of accelerator produced beams, because of the narrow emission angle, this type of calibrations cannot be technical applied.…”

“…Thermoluminescence dosimetry (TLD) is one of the most important techniques used to quantify the absorbed dose, in addition to other techniques based on solid‐state dosimetry such as radiation‐induced absorbance (RIA) . In practice, TLD badges are used for different radiation monitoring applications .…”

Thermoluminescence (TL) materials exhibit a wide range of applications in different areas such as personal dosimetry, environmental dosimetry, medical research etc.Doping of different rare earth impurities in different hosts is responsible for changing the properties of materials useful for various applications in different fields. These materials can be irradiated by different types of beams such as γ-rays, X-rays, electrons, neutrons etc. Various radiation regimes, as well as their dose-response range, play an important role in thermoluminescence dosimetry. Several TL materials, such as glass, microcrystalline, nanostructured inorganic materials and recently developed materials, are reviewed and described in this article.

“…TLDs were most important and widely used passive dosimeters for measuring absorbed dose because of its small size, reproducibilty, re-usability, low hygroscopicity, low fading, lower cost, high senstivity for low dose measurements and good response at high dose measurements. [7][8][9][10][11][12] TLDs are used for monitoring radiation level over a fixed time span. Absorbed energy from intracting particle excite the material or phosphor.…”

In the present work, twelve inorganic thermoluminescence dosimeteric (TLD) materials doped with some rare earth elements (LiF:Sm, LiBaP2O7:Eu, CaCO3:Eu, CaSO4:Dy, SrSO4:Sm, CdSO4:Dy, BaSO4:Eu, Li2B4O7:Dy, MgB4O7:Gd, Al2O3:Gd, MgAl2O4:Ce, and LiCaAlF6:Eu) and three organic TLD materials (C3H7NO2, C7H8O2 and C4H6BaO4) were selected for comparative analysis on the basis of different photon sensing parameters. About nine photon sensing parameters viz. mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), mean free path (mfp), half value layer (HVL), tenth value layer (TVL), effective atomic number (EAN), effective electron number (EEN), exposure buildup factor (EBF), and energy absorption buildup factor (EABF) were obtained for the selected fifteen TLDs. The simultaneous variation of these photon sensing parameters for the selected TLDs with photon energy and composition has been analyzed. This analysis will help radiation physicists to easily select a particular dosimeter for their research laboratory from different existing compositions. All photon sensing parameters strongly depends upon incident energy and chemical composition in lower and higher energy regions. Among the selected TLDs; BaSO4:Eu3+ offers best results (maximum values for MAC, EAN, EEN; minimum values for TNPs, EBF, EABF); whereas MgB4O7:Gd3+ offers EAN value close to tissue and less variation in sensing parameters with respect to energy.
