Abstract
In this research, we studied the graded shielding using one of gamma-ray spectroscopy techniques, which consists of a scintillation detector sodium iodide activated by thallium NaI (Tl) with dimensions of 3"×3" and its electronic accessories .Shielding is fundamentally necessary to minimize the influence of ambient radiation, which consists of single or multiple layers of different materials, such as copper, aluminum and fiberglass, in addition to the lead shield manufactured with a thickness 3cm and through this work it led to reducing the values of the Compton edge and background scattering using industrial source of Cs-137.
This method works to attenuate unwanted complications, which leads to reducing the count rates in some
channels. These new layers should not contain any materials that would add new contributions to the radiation background, ultimately eliminating the complications resulting from the use of the lead shield.Theexperimental results and theoretical conclusion show consistent.
