“…Glasses contain heavy metal oxide (HMO) such as PbO, Bi 2 O 3 , and others have more attention from several technologists, researchers, and investigators due to their interesting structural, physical and physiochemical characteristics like as substantial improvements in their linear/nonlinear optical features and radiation protection application [15][16][17][18][19][20].…”

Potassium lead borate glasses doped with MnO (40B 2 O 3 +40PbO+(20-x)K 2 O+xMnO: x= 0-5 mol%) have been prepared via standard melting quenching process. The impact of MnO on the structure, optical, magnetic and gamma-ray protection properties of pottisium lead borate glasses have been examined. The density was increased from 4.83±0.01 to 5.23±0.01 g/cm 3 as MnO content increased. The obtained direct optical gap (E g ) values were 2.84, 2.59, 2.41, 2.19, 1.95, and 1.84 eV for the Mn-x (x=0, 1, 2, 3, 4, and 5) glass samples, respectively. FTIR spectra demonstrated that as the MnO concentration increases in the glass network the intensity and width of the IR bands were increased. The magnetic measurement revealed that the magnetic situation (M s ) was decreased while the magnetic coercivity (H c ) was increased with increasing MnO substitution ratio. The linear attenuation coefficient of the 𝜇 𝑀𝑛−𝑔𝑙𝑎𝑠𝑠 follows the order: µ Mn-0 < µ Mn-1 < µ Mn-2 < µ Mn-3 < µ Mn-4 < µ Mn-5 . Half value layer (HVL) rises as µ decreases and vice versa. The range of the HVL is 0.002 -3.378, 0.002 -3.334, 0.002 -3.291, 0.002 -3.248, 0.002 -3.176, and 0.002 -3.106 cm for 1,2,3,4, and5). The trend of Z eff variation is related to that of both linear and mass attenuation coefficients (µ and µ m ). The produced Mn-glasses can be employed in a variety of optical, magnetic and radiation protective applications.

“…The MAC of BLa15 decreases from 0.150 to 0.054 cm 2 /g at energies of 0.284 and 1.275 MeV, respectively, while the MAC of BLa25 decreases from 0.164 to 0.053 cm 2 /g for the previously mentioned energies, respectively. Clearly, at higher energies, the difference between the MAC is almost negligible, and this is explained according to the Compton scattering as stated in [23]. At 1.275 MeV, BLa10 has an MAC equal to 0.054 cm 2 /g, while BLa30 has a MAC equal to 0.053 cm 2 /g.…”

The role La2O3 on the radiation shielding properties of La2O3-CaO-B2O3-SiO2 glass systems was investigated. The energies were selected between 0.284 and 1.275 MeV and Phy-X software was used for the calculations. BLa10 glass had the least linear attenuation coefficient (LAC) at all the tested energies, while BLa30 had the greatest, which indicated that increasing the content of La2O3 in the BLa-X glasses enhances the shielding performance of these glasses. The mass attenuation coefficient (MAC) of BLa15 decreases from 0.150 cm2/g to 0.054 cm2/g at energies of 0.284 MeV and 1.275 MeV, respectively, while the MAC of BLa25 decreases from 0.164 cm2/g to 0.053 cm2/g for the same energies, respectively. At all energies, the effective atomic number (Zeff) values follow the trend BLa10 < BLa15 < BLa20 < BLa25 < BLa30. The half value thickness (HVL) of the BLa-X glass shields were also investigated. The minimum HVL values are found at 0.284 MeV. The HVL results demonstrated that BLa30 is the most space-efficient shield. The tenth value layer (TVL) results demonstrated that the glasses are more effective attenuators at lower energies, while decreasing in ability at greater energies. These mean free path results proved that increasing the density of the glasses, by increasing the amount of La2O3 content, lowers MFP, and increases attenuation, which means that BLa30, the glass with the greatest density, absorbs the most amount of radiation.

In the present work, bismuth borate glass samples with the composition of (99-x) B2O3 + 1Cr2O3 + (x) Bi2O3 (x = 0, 5, 10, 15, 20, and 25 wt %) were prepared using the melt quenching technique. The mass attenuation coefficient (MAC) of the prepared glass samples was measured through a narrow beam technique using a NaI(Tl) scintillation detector. Four point sources were used (241Am, 133Ba, 152Eu, and 137Cs) to measure the MAC for the prepared glasses. The experimental data were compared with the theoretical results obtained from the XCOM, and it was shown that for all samples at all tested energies, the relative deviation between the samples is less than 3%. This finding signifies that the experimental data can adequately be used to evaluate the shielding ability of the glasses. The MAC of the sample with x = 25 wt % was compared with different lead borate glasses and the results indicated that the present sample has high attenuation which is very close to commercial lead borate glasses. We determined the transmission factor (TF), and found that it is small at low energies and increases as the energy increases. The addition of Bi2O3 leads to reduction in the TF values, which improves the shielding performance of the glass system. The half value layer (HVL) of the BCrBi-10 sample was 0.400 cm at 0.595 MeV, 1.619 cm at 0.2447 MeV, and 4.946 cm at 1.4080 MeV. Meanwhile, the HVL of the BCrBi-20 sample is equal to 0.171 and 4.334 cm at 0.0595 and 1.4080 MeV, respectively. The HVL data emphasize that higher energy photons tend to penetrate through the glasses with greater ease than lower energy photons. Furthermore, the fast neutron removable cross section (FNRC) was determined for the present samples and compared with lead borate glass and concrete, and the results showed a remarkable superiority of the bismuth borate glass samples.
