Popis: In this report, the physical, optical, and radiation shielding features of 65PbO–(20−x)B2O3–15Bi2O3–xAlO9P3 (x: 0, 2.5, 5, and 7.5 mol%) glasses coded as PBB-Al0, PBB-Al1, PBB-Al2, and PBB-Al3, respectively, are presented. Gamma-ray linear and mass attenuation coefficients were estimated via FLUKA simulations and validated by XCOM calculations for photon energies between 0.1 and 10 MeV. Also, charged particles (electron (e−) proton (p+), α-particle (He2+) and carbon ion (C+)) attenuation competence, $${\Sigma }_{R}, {\sigma }_{tot}$$ , and scattering cross-section for fast, thermal, and cold neutrons of the glasses were estimated. With an increase in AlO9P3 doping rate, the glass density ρglass exhibits a downward trend from 7.358 to 6.987 g⋅cm−3 for PBB-Al0 to PBB-Al3, respectively. Contrary to this, the molar volume Vm grew from 36.06 to 39.77 cm3⋅mol−1, as a function of insertion ratio in AlO9P3 from 0 to 7.5 mol%. Optical parameters such as refractive index (n), dielectric constant (ϵ), molar refractivity (Rm), and molar polarizability (αm) of the glasses were found to vary depending on AlO9P3 content. Analysis of the obtained radiation shielding parameters revealed that gamma-ray shielding capacity of the glasses follows the trend PBB-Al0 > PBB-Al1 > PBB-Al2 > PBB-Al3. However, the influence of Al(PO3)3 on the charged particle shielding abilities of the glasses was insignificant. Furthermore, $${\Sigma }_{R}$$ ranged between 0.1095 and 0.11113 cm−1. $${\sigma }_{tot}$$ for thermal neutron declined as the weight fraction of B, Pb, and Bi declined in the glasses. On the other hand, the scattering cross-section of cold neutrons in the glasses rose throughout the considered energy spectrum as Al(PO3)3 concentration declined in the glass matrix. Comparatively, the investigated PBB-Alx glasses are superior gamma-ray photon shields than ordinary concrete, RS-360 commercial glass shield, P2 polymer, and some recently investigated glass shields. This study concludes that the presently investigated glasses have a significant role to play as alternative radiation shields in contemporary and future application of radiation.
