Energy and chemical composition dependence of mass attenuation coefficients of building materials

Total and partial mass attenuation coefficients of different building materials (glass, concrete, marble, flyash, cement and lime) have been computed over a wide energy range of 10 keV to 100 GeV. For the total mass attenuation coefficient, μtotal a significant variation is observed in low and high energy regions whereas there is no notable change in μtotal in the intermediate region. The results of μtotal have been discussed on the basis of obtained attenuation coefficients of different partial photon interaction processes.
