2014:26 Improved reference and relative dosimetry of small radiation therapy photon beams

Data tables on detector corrections for beam output measurements are provided for a large number of detectors (small air and liquid ionization chambers, silicon diodes, TLD and alanine) manufactured by major vendors, for 6 MV photons from clinical accelerators and for two Leksell Gamma Knife® models. They have been calculated with the PENELOPE Monte Carlo system at an uncertainty of 0.1%. Their comparison with other published data has enabled the determination of the overall uncertainty in the data available for clinical dosimetry.
