Investigating the Attenuation Coefficient for Different Material using X-Ray and Gamma Ray

Abstract

In this research two different source were used with different material in order to investigate the attenuation of x-ray and Gamma- ray as function of the absorber thickness and to compare the effect of this source in attenuation coefficient and to verify Lambert’t law of attenuation. It was found that the attenuation coefficient for X-ray is greater than Gamma ray. It was also found attenuation coefficient of X-ray for Cu is equals 11.7, Fe is equals 6.82 and Al is equals 1.2. The attenuation coefficient of Gamma ray for Cu is equals 0.103, Fe is equals 0.687 and Al is equals 0.0235. Thus Cu is best shielding compared to Fe and Al.
