Abstract:
The dosimetric parameters for characterization of a low-energy interstitial brachytherapy source (125)I are examined. In this work, the radial dose function, g(r), anisotropy function F(r,theta), and the absolute dose rate, Lambda, around (125)I seed model 6711 have been estimated by means of the PENELOPE Monte-Carlo (MC) simulation code. The results obtained are in good agreement with the corresponding values recommended by TG-43 that are based in experimental and MC published results.
