For skeletal muscle tissue, the mass-attenuation coefficient (μ/ρ) at 40-KeV x-ray bean is 2.685x10^-1 (cm^2/g). Taking the density of muscle tissue ρ = 1.05 (g/cm ), calculate the following physical properties for the given X-ray energy: (a) Linear attenuation coefficient, μ (m-1), (b) Half-layer value (HVL) (in meters), and (c) mean-free-path, mfp (in meters).
