In the case of photon beams, the TPR was measured for 6 and 15 MV, also the profiles were determined in order to verify the flatness and symmetry of the beam: This new Code of Practice based 277 standards of absorbed dose to water has been developed for 27 dosimetry of radiotherapy beams when ionization chambers calibrated using these standards are available.

The second dosimeter Scanditronix model DOSE 1 with plane parallel chamber electrons and cylindrical chamber photonsboth chambers calibrated in terms of ND,W. Two independent dosimeters were used with two ionization chambers each one, respectively. Javascript must be enabled for narrowing.


The final draft of TRS can be downloaded from here as a compressed file pdf-zip. In other hand, the use of protocol with a more simple formalism reduces the possibility of errors.

It is determined by two different protocols: Differences in the absorbed dose determined by the three protocols are less than 0. International symposium on standards and codes of practice in medical radiation dosimetry. In the case of N D,w,Qfor all plane parallel chambers, the differences are less than 0.

Calibration of ionization chambers in terms of absorbed dose to water, would reduce the uncertainty in determining the absorbed dose to water in radiotherapy beams versus calibration in air in terms of air kerma.

The IAEA assumes no responsibility for user-calculated results, or for the impact of such upon dose determination. Two water phantoms have been used, one by NE including a waterproof sleeve for cylindrical ionization chambers with thickness about 0. Results 1 – 1 of 1. Please provide a name for this query: 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.
