Chapter 2 described the various processes by which photons interact with matter. These interactions produce charged particles (electrons and possibly positrons) which then travel through matter, losing energy by collision processes (ionization and excitation of atoms) and through radiative processes (production of bremsstrahlung), as illustrated in Figure 3.1.
