Shielding Properties of Al- Cu- Pb Alloys by XCOM and Experimental Data

The current study, the efficiency of many binary and triple aluminum alloys was examined for the alloys samples consisting of (Al-Cu-Pb). These alloys were manufactured in the laboratories of the physics Department and the manufacture of melting furnaces as well as the design of casting molds, and then we used the gamma ray penetration technique to study the behavior of radiation attenuation by the manufactured alloys. The shielding properties of the prepared samples include mass attenuation coefficient ( ), radiation protection efficiency (RPE), half-value layer (HVL), and mean free path (MFP), Which were calculated theoretically using XCOM software. Experimental measurements were made at 60Co (1173, 1332 keV) 137Cs (662 keV) using a Gama spectrometer, which it contains the NaI (Tl) detector. It found that there is a good agreement between the experimental and theoretical values.
