Abstract:
The dosimetry parameters of the IRH10 (192)Ir high dose rate brachytherapy source were obtained from the dose calculation formalism recommended in the AAPM Task Group No. 43 report using the Monte Carlo code PENELOPE. The absorbed doses to water and air originating from the photons of the IRH10 (192)Ir brachytherapy source were calculated by the collision kerma approximation. The dose rate constant was evaluated to be (1.110 +/- 0.011) cGy/h U(-1). The dose rate per unit air kerma strength around the (192)Ir IRH10 brachytherapy source and the anisotropy function were given in tables and figures.
