[en] A series of dosimetric calculations and modeling should be done before the clinical use of any new brachytherapy source. In this work, the capability of the FLUKA Monte Carlo code to simulate praseodymium-142 glass seed as a beta-emitting brachytherapy source was evaluated. The reference dose rate, target dose rate, radial dose function and the anisotropy function were estimated. The agreement between the reported radiochromic film measurements and the FLUKA code outputs indicated that FLUKA as a multipurpose Monte Carlo simulation code can be used to predict the required dosimetric parameters reasonably well.
