“…The intensity of radiation can also be written in terms of the mass attenuation coefficient such as: (μ/ρ) is the mass attenuation coefficient, and ρ is the density of the material. The total mass attenuation coefficient (μ/ρ) for chemical mixture at any reference photon energy is related to the (μ/ρ) of the constituent elements in the mixture (Baldha et al, 1997;Teli, and Chaudhari, 1995;Chaudhari, and Teli, 1996;Teli, and Chaudhari, 1996;Wang, et al, 1995;Singh et al, 2002) and is given by:…”
