Webw) in a Co-60 beam and applying beam quality correction factors, k Q, to account for the variation of the ionization chamber response between the calibration and the clinical beam. According to cavity theory, k Q factors have been expressed in the IAEA TRS- Webcurves by placing chambers (PTW 30013, FC 65G and Semiflex 31010) at the geometrical centers for field size(s) of 5cm × 5cm to 30cm × 30cm at 100cm Source to Surface Distance (SSD) for photon energy 6, 10 and 15MV respectively. The shift of the cylindrical chambers also estimated from PDD values in comparison with reference PDD values by
