propagating through an absorbing medium interact with
atoms by a variety of elastic or inelastic Coulomb force
interactions classified as:
• Inelastic collisions with orbital e

(ionization loss).
• Inelastic collisions with nuclei (radiative loss).
• Elastic collisions with orbital e

.
• Elastic collisions with nuclei (nuclear coulomb scattering).
