Mass absorption and scattering coefficients. When a narrow beam passes through a volume, the beam will lose intensity to two processes: absorption and scattering. Mass absorption coefficient, and mass scattering coefficient are defined as The mass absorption – coefficient (𝜇m) for different absorber materials was obtained by divided the linear absorption coefficient by the density of the absorber.
