Scope

1 This International Standard specifies the performance requirements of radiotherapy dosimeters, as defined in 3.1, intended for the measurement of ABSORBED DOSE TO WATER Or AIR KERMA (and their RATES) in photon or electron radiation fields as used in radiotherapy. NOTE - Throughout this standard: - if no material is specified, the term "ABSORBED DOSE" Or "DOSE" means "ADSORBED DOSE TO WATER (in water)' and the term "KERMA" means "AIR KERMA (in air)"; - when the quantity "AIR KERMA (in air)" in units "Gy" is used, the quantity "EXPOSURE" in units "C/kg" is also allowable. 2 The dose-monitoring systems incorporated in radiotherapy treatment machines are not covered by this standard, neither are the re-entrant ion chambers used for brachytherapy source calibration. 3 This standard is applicable to the following types of DOSIMETER: a) FIELD-CLASS DOSIMETERS normally used for 1) the measurement of KERMA or DOSE in a radiation beam, either in air or in a PHANTOM; 2) in vivo skin surface or intracavitary measurements of DOSE on PATIENTS. b) REFERENCE-CLASS DOSIMETERS normally used for the calibration of FIELD-CLASS DOSIMETERS. NOTE - REFERENCE-CLASS DOSIMETERS may be USed as FIELD-CLASS DOSIMETERS.
