Abstract

© 2022 Elsevier LtdThe radiation shielding properties of some ceramic materials have been measured and obtained results were compared with the simulation. Gamma rays with energy of 662, 1173, and 1332 keV produced from 137Cs and 60Co radioactive sources were utilized in the experimental part of this work to measure linear attenuation coefficients (LAC). A gamma spectrometer with a 3″ × 3″ NaI(Tl) detector, high-voltage electrical components, a preamplifier, an amplifier, and 16384-channel Multi-Channel Analyses (MCA). For simulation the Monte Carlo method to compute and evaluate the linear attenuation coefficients of ceramic materials employed in the human body as synthetic or natural materials. In the simulations conducted with the Gamos 6.2 software, a mono-energetic point photon source geometry between 1 keV and 15 MeV was employed in the computational phase of the investigation by focusing a parallel photon beam toward the absorber material.
