Abstract

A brief description is given of the main radiation-processing applications using photon or electron-beam irradiations, the dosimetry performed for these applications, and the traceability of these absorbed-dose measurements to standards maintained by national laboratories. The properties of nine dosimetry systems, some reference standard dosimetry systems and some used for routine monitoring, are then examined in detail. The descriptions include the reaction mechanisms and the historical background leading to the present systems. Some additional dosimetry systems now in use and some potential new systems are described in less detail.
