    In this study, dose rates and radiation attenuation features of a group of fabricated bioactive glasses were investigated. The borate-based 13-93B3 bioactive glass powders (B3) containing cerium (III), gallium (III) or vanadium (IV) were prepared by melting a homogenized mixture of reagent-grade CaCO3, Na2CO3, MgCO3, K2CO3, H3BO3, CaHPO4.2H2O, Ga2O3, V2O5 or Ce(CH3CO2)3, and disc-shaped scaffolds were prepared by die pressing. Bioactive glasses were modelled by using MCNPX (version 2.7.0) general-purpose Monte Carlo code. A gamma-ray transmission set-up was utilized for determination of mass attenuation coefficients. The obtained coefficients were used for determination of other essential attenuation properties. Finally, exposure (EBF) and energy absorption (EABF) build-up factors were determined. Although the chemical structure of the additive material in bioactive glasses is identical, it can be inferred that the chemical structure of the additive is closely linked to the radiation attenuation characteristics of the bioactive glasses. Results also revealed that, although the bulk densities of the disc-shaped bioactive glass samples were lower than the measured true density values of the melt-derived glass powders due to porosity concerns, they exhibited radiation shielding effect. Findings of the study may be useful in understanding the radiation shielding characteristics of the bioactive glass scaffolds fabricated by powder processing. It can be concluded that outcomes of recent investigation can be useful during the evaluation of potential interactions between the bioactive glasses and medical radiation in the body. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.
