International Atomic Energy Agency. Corrections since CoP publ This new Iea of Practice based on standards of absorbed dose to tfs has been developed for the dosimetry of radiotherapy beams when ionization chambers calibrated using these standards are available. 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 water phantoms have been used, one by NE including a waterproof sleeve for cylindrical ionization chambers with thickness about 0.

The energy parameters characterizing the electron and photon beams have been obtained from measured depth dose distributions carried out by a plane parallel ionization chamber NACP. Reference Number Reference Number. 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. Get permanent URL for this record. In photon beams, absorbed dose to water has been determined at the reference depth recommended in each protocol.

Mexico ; Mar Many standard laboratories already provide calibrations at the radiation quality of 60 Co gamma-rays. Results 1 – 1 of 1.
