Medical electrical equipment. Dosimeters with ionization chambers as used in radiotherapy Ingestion-build-156411 BS EN 102770-4:2008 contains:1 Scope and object 1. 1 Scope This International Standard specifies the performance requirements of radiotherapy dosimeters, intended for the measurement of absorbed dose to water or air kerma (and their rates and spatial distributions) in photon, electron, proton or heavy ion radiation fields as used in radiotherapy. The dose monitoring systems incorporated in radiotherapy treatment machines are not covered by this standard, neither are the re
