Gamma absorption and radiation shielding properties of apatite-wollastonite containing SiO2, Fe2O3, and TiO2

This research presents the gamma interaction parameters of glass-ceramics with the apatite-wollastonite (AW) crystal structure within the SiO2–CaO–Al2O3–MgO–P2O5–CaF2 glass (AW) doped with 10% SiO2 (AW-10Si), Fe2O3 (AW-10Fe), and TiO2 (AW-10Ti) by weight. The density of the glass ceramics was determined based on the Archimedes method while the mass attenuation coefficients (MACs) of the glasses were estimated using the PHITS simulation code for gamma photons within the 15 keV-15MeV energies. The obtained densities of AW, AW-10Si, AW-10Ti, and AW-10Fe are 2.90, 2.92, 2.91, and 3.05 g/cm3, respectively. The linear attenuation coefficients of the glasses followed the order LACAW
