| Abstract | ||||
| In the present study, chemical, mineralogical compositions, petrographic characteristics, physical and mechanical properties and the radiation shielding characteristics of some Egyptian granitic rocks were established and compared with two types of concrete as reference materials (ordinary concrete (OC) and reactive powder concrete (RPC)). Two neutron types, namely slow neutron and neutron with energy greater than 10 keV) have been employed for calculating the macroscopic neutron cross-sections (Σ, cm-1). Different gamma ray energy lines ranged from 121.78 to 1407.92 keV were utilized for evaluating mass attenuation coefficients of gamma rays. Gamma shielding parameters were tested and computed. The results indicated that in the case of fast neutrons, the Ʃ10 for rocks is greater than that of OC and RPC of about 45%, while in the case of slow neutrons, ƩS is greater than that of OC and RPC of about 18%. Further, the results indicated that the three rock types have attenuation behavior favorable than that of OC and RPC in all used γ-rays energies. On the other hand, the calculated mass attenuation coefficient (MAC) using WinXcom computer program and the experimental values showed excellent agreements | ||||
