Abstract
The fields of use of aluminum and its alloys have diversified, making it essential in our daily lives, due to the various properties of aluminum, including light weight, durability, formability, remanufacturability, and resistance to corrosion. It has been used in the aviation industry, high-speed trains, and most advanced engineering industries. Despite the low melting point of aluminum alloys, it is used in the manufacture of missiles and in the construction of internal combustion chambers. Here, aluminum alloys were employed in the fields of protection from electromagnetic radiation, especially gamma rays, by manufacturing gamma ray shields. Three alloys of (AlCuZnxPb10-x) were manufactured, differing in the proportions of zinc and lead elements. The main attenuation parameters were studied, including the linear and mass attenuation coefficient, the value-describing layer, the tenth value layer, and the free path rate, through a theoretical study using the X-COM program. It was noted that with an increase in the zinc concentration, the value of the linear and mass attenuation coefficient increased.
