Procedures of dosimetry with probe-type detectors for photon and electron radiation - Part 2: Ionization chamber dosimetry of high energy photon and electron radiation
Abstract
This document defines specifications for the determination of WATER ENERGY DOSIS and WATER ENERGY DOSIS PERFORMANCE in water with open air-filled ionization chambers according to the probe method in dose measurements for teletherapy a) with 60Co gamma radiation, b) with high-energy photon radiation from clinical linear accelerators with balancing filters with effective acceleration voltages in the range of 3 MV to 25 MV and field sizes of at least 4 cm × 4 cm, c) with high-energy photon radiation from clinical linear accelerators without balancing filters (so-called "flattening filter free beams") with effective acceleration voltages in the range of 3 MV to 10 MV and field sizes of at least 4 cm × 4 cm, d) with electron radiation from clinical linear accelerators with energies in the range of 4MeV to 25 MeV and field sizes of at least 6 cm × 6 cm. Dose measurements in the presence of magnetic fields as used for MR imaging (MRI linacs) and in radiation fields with ultra-high pulse dose rates (FLASH radiation therapy) are not covered in this document.
