Abstract: Fast neutron and gamma-ray attenuation characteristics of Inconel-600, -601, -625, and − 718 superalloys, stainless steel-304, and lead were studied using MCNPX Monte Carlo code, WinXCom, XMuDat, and Auto-Z eff computer programs. The µ m , HVL, MFP, σ a , σ e , Z eff and N eff , and Σ T were calculated for 192 Ir, 18 F, 137 Cs, and 60 Co gamma sources and 1 MeV fast neutrons. The difference between the MCNPX and calculated results was less than ± 2%. Above and below 511 keV photon energy, respectively, Inconel-600 and Inconel-625 have the highest mass attenuation coefficient among Inconel alloys. The thickest HVL and MFP values were achieved for the Inconel-601 superalloy. The σ a and σ e values decreased as photon energy increased. The Z eff values were approximately constant with photon energy increase. The Z eff of the Inconel-601 was the lowest, while that of Inconel-625 was the highest. In the studied gamma-ray energies, the N eff value variations were insignificant. The stainless steel-304 material was found to have the highest Σ T , while Inconel-600 had the highest value between Inconel superalloys. Calculated data indicates that Inconel-600 is the superior candidate for shielding gamma rays among Inconel superalloys.
