Abstract
In the present work, the gamma ray shielding performance of Fe/Cr16/Ni72, Fe/Cr21/Ni32.5, Fe/Cr25/Ni20, Fe/Cr18/Ni10 and Fe/Cr17/Ni7 ternary alloys was investigated. In this respect, some important photon shielding parameters such as the linear and mass attenuation coefficients, mean free path, half, quarter and tenth value layers, effective conductivity and effective atomic number for the selected ternary alloys were determined experimentally in the energy range of 81 keV-1333 keV emitted by Na-22, Mn-54, Co-57, Co-60, Ba-133 and Cs-137 radioactive sources. Besides, the obtained parameters were compared with the calculated values with the help of WinXCOM program based on mixture rule. It is observed that the theoretical results confirmed the experimental results. According to the obtained experimental and theoretical results of all presented parameters, Fe/Cr16Ni72 alloy has the best radiation shielding properties, while Fe/Cr17/Ni7 alloys possesses the worst radiation shielding properties among the selected alloys.
