Influence of MnO on gamma attenuation characteristics of modified borate bioglass

Abstract

Abstract Modified borate Hench glass was successfully synthesized with the composition of (xMnO-(42.5-x)B2O3-28.7CaO-26Na2O-2.8P2O5) where x = (0, 0.1, 0.2, 0.3, 0.4, 0.6, and 0.8) mol% via melting technique and investigated by using different techniques. The density, molar volume, and several physical parameters were calculated. The density has nonlinear behavior by increased MnO due to the manganese ions' nonlinear behavior since they have numerous stable valence states, while the molar volume was increased. The UV/Vis measurement produced a peak that indicated the presence of manganese in Mn3+. The radiation shielding properties of the prepared samples were calculated theoretically using the Phy-X program at energies from 0.015 to 1.5 MeV. Linear and mass attenuation coefficients, as well as half value layer (HVL), tenth value layer (TVL), mean free path (MFP), effective conductivity (Ceff), and exposure buildup factor (EBF), were assessed. The results show that the shielding parameters are affected by MnO concentration and photon energy. Based on the results, it was determined that the synthesized glass sample containing 0.2 mol % MnO has the best optical properties and shielding capabilities, making it great for optical and shielding applications.
