“…Another significant parameter in the radiation shielding field is the tenth value layer (TVL), which is the material thickness needed to attenuate 10% of the initial incident gamma-ray intensity. As shown in Table 2, the half value layer (T1/2) values of the investigated S5 samples were compared with those of Glass1 (Cr2O3-doped BS glass) [40], Glass2 (obsidian glass doped with CeO2) [41], Glass3 (BaO-TiO2-SiO2-B2O3 glass) [42], Glass4 (Li2O-K2O-B2O3-PbO glass) [43], Glass5 (Li2O-K2O-B2O3-HMO (HMO = SrO/TeO2/PbO/Bi2O3)) [44], Glass6 (xBaO-(0.30-x) MgO-0.10Na2O-0.10Al2O3-0.50B2O3 glass) [45], and standard shielding materials (ordinary concrete: OC [46], and hematite-serpentine concrete: HSC [47]); the T1/2 values of the S5 samples were lower than those of all other samples, even OC and HSC. As shown in Table 2, the half value layer (T 1/2 ) values of the investigated S5 samples were compared with those of Glass1 (Cr 2 O 3 -doped BS glass) [40], Glass2 (obsidian glass doped with CeO 2 ) [41], Glass3 (BaO-TiO 2 -SiO 2 -B 2 O 3 glass) [42], Glass4 (Li 2 O-K 2 O-B 2 O 3 -PbO glass) [43], Glass5 (Li 2 O-K 2 O-B 2 O 3 -HMO (HMO = SrO/TeO 2 /PbO/Bi 2 O 3 )) [44], Glass6 (xBaO-(0.30-x) MgO-0.10Na 2 O-0.10Al 2 O 3 -0.50B 2 O 3 glass) [45], and standard shielding materials (ordinary concrete: OC [46], and hematite-serpentine concrete: HSC [47]); the T 1/2 values of the S5 samples were lower than those of all other samples, even OC and HSC.…”

The direct influence of La3+ ions on the gamma-ray shielding properties of cobalt-doped heavy metal borate glasses with the chemical formula 0.3CoO-(80-x)B2O3-19.7PbO-xLa2O3: x = 0, 0.5, 1, 1.5, and 2 mol% was examined herein. Several significant radiation shielding parameters were evaluated. The glass density was increased from 3.11 to 3.36 g/cm3 with increasing La3+ ion content from 0 to 2 mol%. The S5 glass sample, which contained the highest concentration of La3+ ions (2 mol%), had the maximum linear (μ) and mass (μm) attenuation coefficients for all photon energies entering, while the S1 glass sample free of La3+ ions possessed the minimum values of μ and μm. Both the half value layer (T1/2) and tenth value layer (TVL) of all investigated glasses showed a similar trend of (T1/2, TVL)S1 > (T1/2, TVL)S2 > (T1/2, TVL)S3 > (T1/2, TVL)S4 > (T1/2, TVL)S5. Our results revealed that the S5 sample had the highest effective atomic number (Zeff) values over the whole range of gamma-ray energy. S5 had the lowest exposure (EBF) and energy absorption (EABF) build-up factor values across the whole photon energy and penetration depth range. Our findings give a strong indication of the S5 sample’s superior gamma-ray shielding characteristics due to the highest contribution of lanthanum oxide.

New glass systems of bismuth borate with various concentrations of cadmium oxide are prepared based on the melt‐quenching method. The X‐ray diffraction (XRD) reveals a fully amorphous structure of the prepared glasses (S1–S4), and the UV–vis results display good transparency (>50%) in the visible and near‐UV region. In addition, the radiation shielding properties (mass attenuation coefficient, half‐value layer, tenth value layer, mean free path, effective atomic number, and electron density) of the new glass system are determined at selected energies experimentally and by using MCNP5 simulation code and XCOM computer program. Based on the calculated relative difference, the obtained values from MCNP5 and XCOM are in good agreement with the experimental data. The mean free path of the current systems (particularly S4) shows optimistic results when compared with the barite and chalcocite concretes.

“…In Equation ( 1), t represents the thickness of the sample, while I and I 0 in Equation ( 2) are the attenuated and incident intensities of the photons. Moreover, the half value thick-ness (HVL) represents the width of glass that able to shield half of the initial radiation [32]. The smaller the sample thickness that is able to provide adequate radiation protection, the better it will be used in practical applications.…”

This research work aims to investigate the radiation shielding ability of a Yb3+-doped calcium borotellurite glass system. The system has the basic composition of CaF2–CaO–B2O3–TeO2–Yb2O3 but is denoted as TeBYbn for simplicity. The effect of increasing the TeO2 content in the glasses from 10 to 54 mol% was investigated, with five different chosen compositions and densities. The Phy-X/PSD program was used to investigate the mass attenuation coefficient (µ/ρ) of the samples. The mass attenuation coefficients were theoretically determined by using an online software for the calculation of shielding parameters. Other parameters were then calculated and analyzed, such as the linear attenuation coefficient (µ), transmission factor (TF), radiation protection efficiency (RPE), effective atomic number (Zeff), and mean free path (MFP). TeBYb5, the glass with the greatest TeO2 content, was shown to have the greatest µ/ρ; however, at greater energies, the differences between the values are practically negligible. µ was shown to increase with density, such as from 0.386 cm−1 to 0.687 cm−1 for TeBYb1 and TeBYb5 at 0.284 MeV, respectively. The least TF was found for samples with a thickness of 1.5 cm, proving an inverse correlation between the thickness of the sample and the TF. The HVL and TVL of the glasses decreased as the density of the samples increased, which means that TeBYb1 is the least effective out of the investigated glasses. The five samples proved to have a lower MFP than some other shielding glasses, demonstrating their capabilities as radiation shields. Based on the calculated parameters, TeBYb5 indicated the greatest photon attenuation ability.
