Some laboratories have extended calibrations iaeaa high-energy photon and electron beams or are in the stage of developing the necessary techniques for these modalities. The measurements have been performed in two linear accelerators Clinac C Varianwith electron beams of nominal energies between 6 and 20 MeV, corresponding to R 50 from 2.

Mexico ; Mar It is determined by two different protocols: The development of primary standards of absorbed dose to water for high-energy photons and electrons offers the possibility of reducing the uncertainty in the dosimetry of radiotherapy beams.

Beams that are generated by an accelerator Elekta Linac SL In other hand, the use of protocol with a more simple formalism reduces the possibility of errors. Results 1 – 1 of 1. Many standard laboratories already provide calibrations at the radiation quality of 60 Co gamma-rays.
Dosimetry Codes of Practice and Worksheets – IAEA NAHU
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.
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: Please provide a name for this query: International symposium on standards and codes of practice in medical radiation dosimetry.
