Theoretical Calculation of Radiation Shielding Properties of B2O3–Bi2O3–Al2O3–MgO Glasses Alloyed with MnO

The current work aims to calculate the gamma-ray shielding coefficients for six samples. The samples were 65B2O3.20Bi2O3.10Al2O3. (5-x) MgO. xMnO (0 ≤ x ≤ 1 mol%). prepared these samples by using the melt quenching method. The study measures MAC (mass attenuation coefficient) and linear attenuation coefficient (μm, μ). It also calculates the halve-value layer, ten-value layer (TVL), and mean free path (MFP). The calculation was conducted using the Phy-X/PSD and XCOM programs, in an energy range 1 keV–100 GeV. The study discusses comparing the results with each other showing a good agreement. The study has shown many results such as when the energy is higher than 10 MeV. There were many peaks in the low photon energy region (<0.1 MeV). The glass sample with the biggest MnO composition S6 shows many peaks at the M-, L-, and K-absorption photoelectric edges. The measured values that Phy-X/PSD and XCOM software produced showed good agreement. Also, there is a negative correlation between the HVL and material density. In addition, MFP and HVL values begin low and continuously increase as the incident energy of the photon rises to 5 MeV. Beyond 5 MeV, with energies, HVL and MFP dropped softly. Half-Value Layer values drop with the rise in the density and MnO contents.
