"Linear attenuation coefficient (µ) is a constant that describes the fraction of attenuated incident photons in a monoenergetic beam per unit thickness of a material 1. It includes all possible interactions including coherent scatter, Compton scatter and photoelectric effect 1. Its complement is the transmitted portion of the beam. It is expressed numerically in units of cm-1."
"The mass attenuation coefficient is a normalisation of the linear attenuation coefficient per unit density of a material producing a value that is constant for a given element or compound (i.e. it is independent of the density of the material) 1,3. It is expressed in cm2/g (square centimetres per gram)."
