Interactions of Charged Particles with Matter
In this chapter we discuss interactions of charged particle radiation with matter. A charged particle is surrounded by its Coulomb electric field that interacts with orbital electrons and the nucleus of all atoms it encounters, as it penetrates into matter. Charged particle interactions with orbital electrons of the absorber result in collision loss, interactions with nuclei of the absorber result in radiation loss. The energy transfer from the charged particle to matter in each individual atomic interaction is generally small, so that the particle undergoes a large number of interactions before its kinetic energy is spent.
