Investigation of Gamma Shielding Properties of Some Industrial Materials

Abstract

This paper has investigated the radiation absorption properties of some industrial materials. The most widely used for industrial purposes gamma radioisotope source is60Co. In this study, the linear attenuation coefficients of some industrial samples (Aluminium, AISI 4140 alloy steel, and AISI 4130 alloy steel) have been measured experimentally at 1173, and 1332 keV photon energies using a gamma spectrometer that contains a 3”x3” NaI (Tl) detector that is connected to Multi-Channel Analyzer (MCA) and calculated theoretically with the XCOM computer program. These results have been used to calculate the obtained radiation shielding parameters. The calculations from experimental methods were observed to be consistent with the XCOM data. As a result of this study, it was seen that AISI 4130 alloy steel has the largest linear absorption coefficients (0.487 and 0.364 cm-1) at 1173 and 1332 keV energies, whereas aluminium has the lowest values (0.177 and 0.106 cm-1). In addition, it was seen that the industrial samples used in this study were more suitable among radiation shielding materials compared to granite and concrete samples in previous studies.
