Determination of photon-shielding features and build-up factors of nickel–silver alloys

摘要: Abstract In this study, a comprehensive study on photon and fast neutron interactions was conducted to determine the possible uses of four different copper-based Nickel–Silver (NS) alloys as alternative protective materials. For purpose, interaction parameters (μ, μm, X1/2, σT, Zeff, Neff, Ceff) NS which have Cu65Ni18Zn17, Cu62Ni18Zn20, Cu64Ni12Zn24 Cu55Ni18Zn27 compositions were presented experimentally in energy range 30–1333 keV using ideal transmission geometry conditions. order compare experimental theoretical results evaluation wide (0.015–15 MeV), these also calculated WinXCOM based Phy-X/PSD software. It found that there is good agreement between results, maximum relative difference approximately 1.2%. test suitability radiation shielding capacities studied for nuclear applications, all theoretically ordinary concrete (OC), basalt (BM) steel magnetite (SM) concretes. Furthermore, exposure build-up factors concretes G-P fitting method at from 0.015 15 MeV up 40 mean free path (MFP) penetration depth. Moreover, removal cross-sections materials determined According data obtained, it has been observed are far superior selected both neutrons. revealed may be an material candidate due their high density, melting points (about 1100 °C) mechanical strength.
