摘要

The main objective of the present study is to investigate the shielding characteristics of charged particles, gamma rays, and fast neutrons for magnesium alloys. Despite the extensive utilization of these alloys in electromagnetic shielding applications, their radiation shielding properties are not available in the literature, to the best of our knowledge. Consequently, this study aims to address this knowledge gap by providing a comprehensive and comparative analysis of the radiation protective abilities of the alloys. To this end, the radiation shielding parameters are evaluated through the utilization of the PHITS, PAGEX, SRIM and Phy-X/PSD codes. Moreover, a comprehensive and comparative analysis of the results is conducted. Observations are made concerning the proportionality of shielding effectiveness for charged particles (protons and α-particles), neutrons and gamma rays, as a function of aluminum, copper, zirconium, lithium, tin, manganese, calcium, lanthanum, cerium, gadolinium, samarium and yttrium contents for binary, ternary and quaternary Mg alloys. It is determined that the alloys including contents of lanthanum, gadolinium, yttrium and samarium were characterized by enhanced levels of protective properties. Among the alloys, the highest protective feature is observed for Mg-Zn-Sm, Mg-La, Mg-Sm and Mg-Gd, respectively, and the lowest one is seen for Mg-Li, Mg-Al-Ca-Mn, Mg-Zn-Mn and Mg-Zn-Ca-Ce, respectively.
