Mexico ; Mar The IAEA assumes no responsibility for user-calculated results, or for the 27 of such upon dose determination. The calibration is performed in terms of absorbed dose to water Dw. Javascript must be enabled for narrowing.

Beams that are generated by an accelerator Elekta Linac SL In this case, chamber dependent conversion factors are required to determine absorbed dose to water.

In the case of N D,w,Qfor all plane parallel chambers, the differences are less than 0. Citation Export Print Permalink Translate. Mexican symposium on medical physics; Guanajuato, Gto. Two water phantoms have been used, one by NE including a waterproof sleeve for cylindrical ionization chambers with thickness about jaea.

A link to the worksheets is provided at the bottom of this page. Many standard laboratories already provide calibrations at the radiation quality of 60 Co gamma-rays. The results obtained for the absorbed dose quotients D W,Q d max are: Get permanent URL for this record. International symposium on standards and codes of practice in medical radiation dosimetry.

Reference Number Reference Number. The energy parameters characterizing the electron 2277 photon beams have been obtained from measured depth dose distributions carried out by a plane parallel ionization chamber NACP. International Atomic Energy Agency. 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. In creating this software, every effort has been made to create conditions that minimize input errors.
