Definition

quotient of the linear attenuation coefficient $μ$ (linear attenuation coefficient <ionizing radiation>) and the mass density $ρ$ (ISO 80000-4: Mechanics) of the medium:

μ_{m} = μ / ρ

quotient du coefficient d'atténuation linéique $μ$ (linear attenuation coefficient <ionizing radiation>) par la masse volumique $ρ$ (ISO 80000-4: Mechanics) du milieu:

μ_{m} = μ / ρ
