“…According to Table 1, Fig. 7 Half-value layer (HVL) values as a function of photon energy of all the samples produced then become almost constant due to pair production process [42]. Comparable results have been achieved in the previous studies [43][44][45].…”

In this study, optical properties and nuclear protective efficiency of newly fabricated PbO-GeO 2 glass samples (GP) fabricated with different concentration of TiO 2 (0.2%, 0.5%, and 4%, in wt%) were investigated. PbO-GeO 2 glass samples have been prepared by the conventional melt-quenching method. Using optical absorption spectra, band gap and optical properties of the PbO-GeO 2 glass samples were evaluated. In addition, mass attenuation coefficient values of the fabricated glass samples were calculated in the energy range of 0.015-15 MeV using MCNPX simulation and the theoretical WinXcom program. In addition, several nuclear shielding parameters were calculated for gamma ray and neutrons such as half-value layer, mean free path, effective atomic number (Z eff ), exposure buildup factor, energy absorption buildup factor, and fast neutron removal cross sections (Σ R ). The results showed that glass sample with 0.2% of TiO 2 and with the highest density has an excellent nuclear radiation shielding ability for gamma ray, whereas the one with the highest TiO 2 contribution (4.0% of TiO 2 ) has a better protection against fast neutrons shielding among the produced glass samples. The results also showed a slight change for the E opt with TiO 2 concentration and the same applies to the refractive index. However, E opt tends to decrease when TiO 2 concentration increases and, consequently, the refractive index tends to increase.

“…It can be observed from the figure 11 that increasing photon energy has increased the requirements of half value layer thicknesses for all the glass samples. This can be attributed to process of gamma-ray / material interaction that higher energy gamma-rays need thicker material for being decreased to half of original intensity [29,30]. As previously discussed, Dy2.5 material demonstrated remarkable μ values.…”

In this study linear/nonlinear optical and γ-photon attenuation competences of dysprosium oxide (Dy3+ ions) doped zinc-aluminoborosilicate glasses based on (40−x) B2O3—20SiO2 –10Al2O3 –20NaF—10ZnO—xDy2O3, (where x = 0, 0.1, 0.5, 1.0. 1.5, 2.0 and 2.5 mol%) were investigated. Different types of calculation methods along with Monte Carlo simulations were used for determination of linear/nonlinear optical and γ-photon attenuation competences. Both molar refractivity (Rmolar) and molar polarizability (α molar) decreased as Dy3+ ions concentration increased. The optical transmission (Toptical) of the investigated glasses varied inversely to their reflection loss (Rloss). The obtained values of metallization criterion (Mcriterion) quantity showed that the studied glasses are insulator materials. The results also showed that Dy2.5 sample with the highest amount of Dy2O3 additive has the highest mass attenuation coefficients (μ m) and effective atomic number (Zeff) values. On the other hand, Half (HVL) and tenth (TVL) value layers were reported as (HVL, TVL)Dy0.0 > (HVL, TVL)Dy0.1 > (HVL, TVL)Dy0.5 > (HVL, TVL)Dy1.0 > (HVL, TVL)Dy1.5 (HVL, TVL)Dy2.0 > (HVL, TVL)Dy2.5. The maximum and minimum values of exposure and energy absorption buildup factors (EBF and EABF) were reported for Dy0.0 and Dy2.5 samples, respectively. It can be concluded that studied glasses are candidate materials for optical fibers and photonic devices. It can be also concluded that Dy2.5 sample is the superior sample in terms of gamma-ray attenuation competences.

“…In circumstances when concrete or other materials such as polymers or metals fail, glasses can be utilized as a protective layer. Different research groups have since explored tellurite, lithium borate, silicate, lead fluoroborate, bismuth-borate, commercial glasses, and zinc borotellurite glasses for their possible use as photon shielding materials [6][7][8][9][10][11][12]. Tellurium dioxide (TeO 2 ) is the most stable oxide of tellurium.…”

Transmission Factor (TF) Behavior of Bi2O3–TeO2–Na2O–TiO2–ZnO Glass System: A Monte Carlo Simulation Study

et al. 2022

The main objective of the present work was to assess the gamma radiation shielding competencies and gamma radiation transmission factors (TFs) for some tellurite glasses in the form of Bi2O3–TeO2–Na2O–TiO2–ZnO. MCNPX general-purpose Monte Carlo code (version 2.6.0) was utilized for the determination of TF values at various well-known radioisotope energies for different glass thicknesses from 0.5 cm to 3 cm. Moreover, some important gamma ray shielding properties were also determined in the 0.015–15 MeV energy range. The results show that glass densities were improved from 5.401 g/cm3 to 6.138 g·cm3 as a function of Bi2O3 increment in the glass composition. A S5 glass sample with the maximum Bi2O3 additive was reported with superior gamma ray shielding properties among the studied glasses. It can be concluded that Bi2O3 can be used as a functional tool in terms of improving glass density and, accordingly, gamma ray shielding attenuation properties of tellurite glasses, where the role Bi2O3 is also critical for other material properties, such as structural, optical, and mechanical.
