In numerous tissue engineering and dental applications, bioactive glasses are utilized.

These glasses have unique characteristics that make them attractive candidates for a variety of applications. A new bioactive glass system with the structure of 45P2 O5 __ 20CaO __ 15CaCL2 __ 8KF __ (10 __ x) Li2 O __ (x) TiO2 was developed in this study, with x = 2, 6, and 8 mol%. For usage in radiation protective applications, it was evaluated. By using an ultraviolet–visible spectrophotometer, we were able to measure the absorbance (Abs) and transmittance (T %) in the range of wavelengths 190–2500 nm. Furthermore, the optical energy gap of the produced glasses was determined. Using the MIKE software, the mass attenuation coefficients (MAC) of the bioactive glasses under investigation were calculated for energies ranging from 15 to 200 keV. The LAC, zeff , Neff , HVL, TVL, and MFP (Linear attenuation coefficient, effective atomic number, effective electron density, half value layer, tenth value layer, and mean free path) of the bioactive glasses were calculated. According to the findings, the addition of titanium dioxide (TiO2) as well as the metal oxide such as Li2O to bioactive glasses generates significant differences in the attenuation characteristics of bioactive glasses. The results indicate that the PCKLT3( Ti02 = 8mol%) bioactive-glass sample had the best attenuation among other samples.
