Studies of bioactive glasses give an advanced roadbook to realize radiation applications in nuclear medicine and other medical applications. This paper aims to investigate the gamma ray interaction parameters of the PbCl2–SnCl2–P2O5 glass system. The mass attenuation coefficients (μm) of the selected bioactive glasses have been obtained using XCOM and dosimetry Phy-X/PSD programs in the photon energy range 10–150 keV and also correlated with those simulated through MCNP5 code. The other parameters, such as the effective atomic number (Zeff), electron density (Ne), and mean free path (MFP), tenth-value layer (TVL), and half-value layer (HVL) values have also been computed. Among all the selected bioactive glasses, the S4 bioactive glass has the lowest MFP, HVL, and TVL, showing that it is highly effective in absorbing gamma rays. The values of MFP of all samples (S1–S8) are also compared to the RS 253G18 and RS 360 commercial glasses at energy 150 keV. The fast neutron removal cross-sections have been obtained to study the fast neutron absorption behavior with the selected bioactive glasses.
