N2 - This research is devoted to studying the radiation-protecting characteristics of calcium titanate (CaTiO3) perovskite-based ceramic material. The ceramics were made by the solid-state reaction method (SSRM) and treated at temperatures of 1300 degrees C, 1200 degrees C, and 1100 degrees C. The structural characteristics of the ceramics were analyzed by XRD and FT-IR. The results indicated a CaTiO3 phase formation with an orthorhombic structure. The size of the crystallites was in the range of 27-36 nm and was found to increase as the temperatures increased. The relative density showed an increase from 93% to 96% as the temperatures varied from 1100 degrees C to 1300 degrees C. The impact of temperature on the radiation-protecting characteristics of the CaTiO3 ceramic was assessed using the Monte Carlo simulation (MCS). There was a slight decrease in the gamma-photons average track length with a raising of the temperature. At a gamma-photon energy of 0.662 MeV, the gamma-photons' average track lengths diminished from 3.52 cm to 3.38 cm by raising the temperature from 1100 degrees C to 1300 degrees C. The illustrated decrease in the gamma-photons average track length affected the linear attenuation coefficient (mu) where the mu increased from 0.28 to 0.30 cm(-1) with a rising temperature from 1100 degrees C to 1300 degrees C.
