Abstract
The dose of radiation is a central issue in radiotherapy. Hence dosimetry must be well understood for anyone working in this field. In this chapter theoretical aspects as well as practical aspects of the dosimetry of high energy photons and electrons are addressed. The practical aspects are exclusively dedicated to the determination of absorbed dose to water in terms of Gray using ionization chambers under so-called reference conditions frequently referred to as beam calibration. The procedures described for that are following the concepts as outlined in the IAEA document “Absorbed Dose Determination in External Beam Radiotherapy: An International Code of Practice for Dosimetry based on Standards of Absorbed Dose to Water”, Technical Report Series no. 398.
