“…Nevertheless, at all energies, the C-N15 sample had the greatest LAC out of these three samples. The half-value layer (HVL) is an important radiation shielding parameter [36][37][38][39]. The HVL for C-0, C-B5, C-N5, C-N10, and C-N15 is illustrated in Figure 6.…”

“…Moreover, when comparing C-B5 and C-N5, which both have the weight fraction of Bi2O3, it can be seen that the HVL for the concrete with NP Bi2O3 is lower than that of bulk Bi2O3, which means that the use of NPs decreases the thickness of the concretes and improves their ability to shield photons. The half-value layer (HVL) is an important radiation shielding parameter [36][37][38][39]. The HVL for C-0, C-B5, C-N5, C-N10, and C-N15 is illustrated in Figure 6.…”

The aim of this study is to investigate the radiation shielding properties of novel concrete samples with bulk Bi2O3 and Bi2O3 nanoparticles (Bi2O3 NP) incorporated into its composition. The mass attenuation coefficient of the concrete samples without Bi2O3 and with 5 and 7 wt% bulk Bi2O3 were experimentally determined and were compared against values obtained using the XCOM and Geant4 simulations. Both methods greatly agree with the experimental values. The linear attenuation coefficients (LAC) of blank concrete (C-0), concrete with 5% bulk Bi2O3 (C-B5), and concrete with 5% nanoparticle Bi2O3 (C-N5) were determined and compared at a wide energy range. We found that the LAC follows the trend of C-0 < C-B5 < C-N5 at all the tested energies. Since both C-B5 and C-N5 have a greater LAC than C-0, these results indicate that the addition of Bi2O3 improves the shielding ability of the concretes. In addition, we investigated the influence of nanoparticle Bi2O3 on the LAC of the concretes. The half-value layer (HVL) for the concretes with bulk Bi2O3 and Bi2O3 nanoparticles is also investigated. At all energies, the C-0 has the greatest HVL, while C-N15 has the least. Thus, C-N15 concrete is the most space efficient, while C-0 is the least space efficient. The radiation protection efficiency (RPE) of the prepared concretes was found to decrease with increasing energy for all five samples. For C-0, the RPE decreased from 63.3% at 0.060 MeV to 13.48% at 1.408 MeV, while for C-N15, the RPE decreased from 87.9 to 15.09% for the same respective energies. Additionally, C-N5 had a greater RPE than C-B5, this result demonstrates that Bi2O3 NP are more efficient at shielding radiation than bulk Bi2O3.

This paper studies the role of B2O3 in the radiation shielding properties of (100-x)(60TeO2-40PbO)-xB2O3 glass systems where x = 0, 1, 2, 3, 4 and 5 mol%. Through the scanning electron microscope (SEM) and X-ray diffraction (XRD) tests of the glass, the structure of the glass was studied. Physical radiation sources (57Co, 60Co, 137Cs, 133Ba, and 241Am) and WinXCOM software were used to experimentally and theoretically calculate the radiation properties of the glass, respectively. The gamma shielding ability of the glass was evaluated using its mass decay coefficient (μm), half-value layer (HVL), mean free path (MFP) and effective atomic number (Zeff). The neutron shielding ability of the glass was evaluated by calculating the fast neutron removal cross-section (RCS) value. The glass’s gamma and neutron shielding properties were compared to various ordinary concrete and other tellurite glasses. The measured mass decay coefficients agree well with the theoretical values obtained using WinXCOM software. Low HVL, MFP, and high μm, Zeff, and RCS values indicate that this series of glass materials have good shielding properties. According to the obtained results, among the glass samples doped with B2O3, the TPB-1 glass sample showed the best radiation shielding performance.

Ag 2 O-MoO 3 -V 2 O 5 -TeO 2 (AMVT) glasses were reported by means of their optical properties such as polarizability, optical transmission, and optical basicity. Moreover, the photon attenuation properties were explored by using FLUKA simulation code for energies up to 1.275 meV. From the optical study, it was noted that the molar polarizability (α Mol. ) decreased from 11.8630 × 10 -24 to 9.4846 × 10 -24 cm 3 , while the optical transmission increased from 0.5498 to 0.5976 as the Ag 2 O concentration increased from 0 to 25 mol%. From the photon attenuation study, the maximum values of µ/ρ (MAC, mass attenuation coefficient) were observed at 0.284 meV. Such those values were 0.1501, 0.1525, 0.1549, 0.1572, 0.1593 and 0.1616 cm 2 /g for AMVT1, AMVT2, AMVT3, AMVT4, AMVT5 and AMVT6, respectively. From the view of practical application, it is found that the HVL values of the AMVT glasses are evidently lower than those of ordinary concrete and RS-253-G18 commercial glass.
