what are the processes of attenuation
absorption and scattering
what is absorption
transference of energy from the radiation to the medium
what is scattering
the change in the direction of a photon, with or without the loss of energy from a photon
what are the 2 attenuation coefficients
total linear attenuation coefficient
total mass attenuation coefficient
what is attenuation coefficient
tells us how effective different materials are at attenuating radiation
what is total linear attenuation coefficient
fraction of x rays removed from the beam per unit thickness of a medium
it will change as the density of the medium changes
what is total mass attenuation coefficient
the fraction of x rays removed from the beam per unit mass of a medium
