Calculation and Study of Gamma ray Attenuation Coefficients for Different Composites	2017	9	.pdf	application/pdf	2282	95	59	The total linear attenuation coefficients of gamma ray for 15 composites have been calculated using the XCOM program (version 3.1) in the energy range of 0.1-20 MeV. Key words: linear attenuation coefficients, composite materials, gamma ray. In fig (1) , the linear attenuation coefficient ( µ ) was displayed as a function of the applied energy, it was clear that linear attenuation coefficient ( µ ) sharply decreased with the increase of the photon energy in the range (0.1-1) MeV for all composites .Such	cache/iajs-576.pdf	txt/iajs-576.txt
