Webb2. The Mass Attenuation Coefficient, μ / ρ. from which μ / ρ can be obtained from measured values of Io, I and x. Note that the mass thickness is defined as the mass per unit area, and is obtained by multiplying the thickness t by the density ρ, i.e., x = ρt . The various experimental arrangements and techniques from which μ / ρ can be ...
