IEC 60731:2011 PDF

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-entrant IONIZATION CHAMBERS used for BRACHYTHERAPY source calibration and constancy check devices. 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. c) SCANNING-CLASS DOSIMETERS normally used for relative dose distribution measurements with a SCANNING SYSTEM such as an automatic water PHANTOM.
