WebThe amount of attenuation depends on the material of the shield, its thickness, and the photon energy. The literature gives values of the mass attenuation coefficient μ/ρ, which is the ratio of the linear attenuation coefficient μ (macroscopic cross section Σ) and the material density ρ; thus it has units cm 2 /g.
