Gamma-ray and fast neutron shielding characteristics of inconel super alloys, stainless steel-304, and Pb using MCNPX, WinXCom, XMuDat, and Auto-Zeff software
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<sub>eff</sub> computer programs. The µ<sub>m</sub>, HVL, MFP, σ<sub>a</sub>, σ<sub>e</sub>, Z<sub>eff</sub> and N<sub>eff</sub>, and Σ<sub>T</sub> were calculated for <sup>192</sup>Ir, <sup>18</sup>F, <sup>137</sup>Cs, and <sup>60</sup>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<sub>a</sub> and σ<sub>e</sub> values decreased as photon energy increased. The Z<sub>eff</sub> values were approximately constant with photon energy increase. The Z<sub>eff</sub> of the Inconel-601 was the lowest, while that of Inconel-625 was the highest. In the studied gamma-ray energies, the N<sub>eff</sub> value variations were insignificant. The stainless steel-304 material was found to have the highest Σ<sub>T</sub>, 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.
