Radiation shielding is a popular subject in physics due to its widely utilization in different fields in the paralel of technological development and thus recently many recearches have focused in this subject. Most of works were performed using simulation code as experimental studies are more difficult and required technical setup. The simulation works performed in this study to obtain radiation shielding properties of marble concretes at the gamma rays energies of 0.511, 0.835 and 1.275 MeV. The simulation were done using Phy-X/PSD code in order to obtain the linear attenuation coefficients (µ, cm⁻¹). Some other radiological parameters such as mean free path (mfp), half value length (HVL), tenth value length (TVL), Effective atomic number (Z_eff), electron density (N_eff), Equivalent atomic number (Z_eq), Exposure Buildup factor (EBF), fast neutron removal cross section (FNRC), and Zeq were also obtained.

大理石混凝土放射参数的模拟研究

辐射屏蔽由于其在技术发展的并行领域中的广泛应用而在物理学中很受欢迎，因此最近许多研究都集中在该主题上。大多数工作都是使用仿真代码执行的，因为实验研究更加困难且需要进行技术设置。在这项研究中进行的模拟工作是为了在0.511、0.835和1.275 MeV的伽马射线能量下获得大理石混凝土的辐射屏蔽性能。为了获得线性衰减系数（μ，cm ^-1），使用Phy-X / PSD代码进行了仿真。其他一些放射学参数，例如平均自由程（mfp），半值长度（HVL），十分值长度（TVL），有效原子序数（Z _eff），电子密度（N _eff），等效原子序数（Z _eq），暴露累积因子（EBF），快速中子去除截面（FNRC）和Zeq。
