Calculation of The Effects of Fly Ash in Concrete Samples Used as Construction Materials on Radiation Shielding Efficiency Using EGS4 Code
Abstract
The aim of this study is to determine the effects of reducing cement and replacing it with fly ash in concrete samples used as construction materials on the radiation shielding efficiency. The radiation shielding effect of concrete samples was determined using the EGS4 code. By contrasting the outcomes with XCOM data, theoretical discussion was conducted. At gamma ray energies between 59.5 and 1332 keV, the mass attenuation coefficients (μ/ρ) of concrete samples mixed with fly ash were theoretically investigated using WinXCOM and EGS4. Then, several shielding parameters, including mean free path (MFP), half value layer (HVL), radiation protection efficiency (RPE), effective atomic number (Zeff), and gamma-ray kerma coefficients (kγ), were found using the mass attenuation coefficients. It has been noted that the parameters governing radiation shielding performance of concrete samples used as building materials are altered when cement is reduced and fly ash is substituted.
