• The desired target of the current report was to examine the efficiency of MnO-based glass systems against x- or g-rays, and mechanical properties with varying amounts of MnO incorporation. The focus was on evaluating their radiation shielding performance and determining their elasto-mechanic intrinsic characteristics. Various gamma and neutron shielding factors, including HVL (half-value layer), Z eff ( Z eff : effective atomic number), Z eq (equivalent atomic number), EBF (exposure buildup factor), EABF (energy absorption buildup factor), ACS (atomic cross-section), ESC (electronic cross-section), and SAFE * (specific absorbed fraction of energy) were planned to assess the radio-protection capabilities of the probed glass systems. Exemplified at E  = 15 keV, the MAC (mass attenuation coefficient) values are: 13.99 cm 2 /g, 14.03 cm 2 /g, 14.18 cm 2 /g, 14.36  cm 2 /g, and 14.55 cm 2 /g for the glass blocks encoded as LZBP, 0.1Mn:LZBP, 0.5Mn:LZBP, 1.0Mn:LZBP, and 1.5Mn:LZBP respectively, while the SAFE values vary between 31907 g −1 and 32013 g −1 as Mn 2+ is increased from 0.0 mol% to 1.5 mol%. The outcomes indicate that as the manganese (II) oxide mol% increases, then the MAC, Z eff , Z eq , ACS, and ESC values also increase. Among the samples, 1.5Mn:LZBP exhibited the least HVL, EBF, EABF, and SAFE values. This glass, which contains 1.5 mol% of MnO and has the highest interconnecting bonding/volume, may be deemed as an advanced glass for ray protection in the different fields, providing valuable insights into their radiation shielding performance.
