The energy parameters characterizing the electron and photon beams have been obtained from measured depth tgs distributions carried out by a plane parallel ionization chamber NACP. It is determined by two different protocols: Furthermore, users can download the most final version of the Code of Practice to date, with corrections and updates inserted, from here. The development of primary standards aiea absorbed dose to water for high-energy photons and electrons offers the possibility of reducing the uncertainty in the dosimetry of radiotherapy tds.
Two water phantoms have been used, one by NE including a waterproof sleeve for cylindrical ionization iafa with thickness about 0. This new Code of Practice based on standards of absorbed dose to water has been developed for the dosimetry of radiotherapy beams when ionization chambers calibrated using these standards are available. Reference Number Reference Number.
In this case, chamber dependent conversion factors are required to determine absorbed dose to water. High Energy Photons and Electron Beams. Publication Year Publication Year.

An errata file for the printed version is also available here: Many standard laboratories already provide calibrations at the radiation quality of 60 Co gamma-rays. These factors do not account differences aiea individual chambers of a particular type. Corrections since CoP publ Some laboratories have extended calibrations to high-energy photon and electron beams or are in the stage of developing the necessary techniques for these modalities.

Two independent dosimeters were used with two ionization chambers each one, respectively.
The second dosimeter Scanditronix model DOSE 1 with plane parallel chamber electrons and cylindrical chamber trssboth chambers calibrated in terms of ND,W. The quality for electrons beams were estimated by means of the Dmax, R80, R50 and Rp.
The calibration is performed in terms of absorbed dose to water Dw. Evaluation of codes of practice: Standard Search Advanced Search.
