The basic processes in solid-state radiation detectors, with main emphasis on their influence on energy resolution, are overviewed. We discuss the statistics of the number of electron–hole pairs, scintillation light yield dependent on the incident energy of γ rays, and the energy transfer process in scintillators that have dopants as luminescence centers. These processes are discussed in relation with the initial processes in radiation chemistry.

Key words: Fano factor; energy resolution; non-proportionality; scintillation; energy transfer
