Comparison of Gamma Sources (Cobalt and Cesium) for Density Measurement of Metals and Alloys via Using Transmission Technique

Abstract

One of the solutions for density measurement is to make use of gamma-ray transmission technique. We studied by this technique, using by Co-60 and Cs-137. Each source, without materials in geometry, was counted and noted intensities as (I0). All materials were counted and noted intensities as (I). [I/I0] rates were calculated. Now, density of materials could be determined via using Beer-Lambert Equation. Experimental application was performed on industrial metals or metal alloys like lead&copper and steel&brass. Given densities and obtained densities were compared. Differences or deviations for lead, stell copper and brass are -5.07; 0.26; 1.11; -5.73 (Co-60) and 1.07; 3.08; -0.22; 2.34 (Cs-137) consequently. It could be said that, these differences are still in acceptable limits.
