Abstract

In this work, the x-ray shielding properties of novel 45Na 2 O + 10 Bi 2 O 3 + (5 - x)TiO 2 + (x) Nb 2 O 5  + 40 P 2 O 5 , were x = 0, 1, 3, 5 mol%, glass materials were studied using the Phy-X/PSD software and geant4 was used to validate the funding’s. The results revealed that sample S1 (with no Nb₂O₅) exhibited the lowest LAC (ranging from 95,129.721 cm⁻¹ at 15 keV to 2.956 cm⁻¹ at 80 keV), whereas sample S4 (with 5 mol% Nb₂O₅) had the highest LAC, confirming that increasing Nb₂O₅ enhances X-ray shielding. The sample S4 with 5 mol% of Nb 2 O 5 has the highest linear attenuation coefficient (6.861–0.703 cm − 1 ) at photon energies between 80 to 300 keV. These calculations indicated that adding more Nb 2 O 5 content makes the glass more effective for shielding X-rays in this low energy range.
