ABSTRACT

Accurate dosimetry requires an understanding of the relationship between the energy deposited in the medium by the radiation source and the signal produced by the detector. In scintillators, the conversion of energy from radiation into visible light depends on the radiation interaction mechanism and the physical and temporal distribution of the radiation on the microscopic level, also known as the quality of the radiation (ICRU 1970). The physical mechanism of scintillation in organic materials was described in detail in Chapter 1. This chapter focuses solely on the effect of the quality of the radiation on the production of scintillation light.
