NEN-EN-IEC 62467-1 specifies the performance and some related constructional requirements of WELL-TYPE IONIZATION CHAMBERS and associated measurement apparatus, as defined in Clause 3, intended for the determination of a quantity, such as AIR KERMA STRENGTH or REFERENCE AIR KERMA RATE in photon radiation fields or ABSORBED DOSE TO WATER at a depth, in photon and beta radiation fields used in BRACHYTHERAPY, after appropriate calibration for a given type of source. This International Standard covers the techniques for the quantification of the quantity appropriate for the BRACHYTHERAPY source under consideration. This quantity may be AIR KERMA STRENGTH or REFERENCE AIR KERMA RATE at 1 m, or ABSORBED DOSE TO WATER at a depth (e.g. 2 mm or 5 mm). Measurement of these quantities may be accomplished by a variety of WELL-TYPE IONIZATION CHAMBERS or systems currently available for this purpose. This standard applies to products intended for low dose rate, high dose rate, intravascular, both photon and beta, BRACHYTHERAPY measurements. It does not apply to instruments for nuclear medicine applications. The application of the standard is limited to instruments that incorporate WELLTYPE IONIZATION CHAMBERS as detectors. The intended use is the measurement of the output of radioactive, encapsulated sources for intracavitary (insertion into body cavities) or interstitial (insertion into body tissue) applications. The object of this standard is a) to establish requirements for a satisfactory level of performance for WELL-TYPE CHAMBER SYSTEMS, and b) to standardize the methods for the determination of compliance with this level of performance. This standard is not concerned with the safety aspects of WELL-TYPE CHAMBER SYSTEMS. The WELL-TYPE CHAMBER SYSTEMS covered by this standard are not intended for use in patient environment. The electrical safety of WELL-TYPE CHAMBER SYSTEMS is covered in IEC 61010-1. The operation of the electrometer measuring system is covered in IEC 60731
