| Abstract: | This work determined a new Monte Carlo code(FLUKA) that can be used to calculate the dosimetric characteristics of seed sources. Dosimetric parameters(dose rate constant, radial dose function, and anisotropy function) of model 6711125 I seed source were calculated with FLUKA. The results were compared to the relative data recommended by AAPM TG43U1: dose rate constant with FLUKA was in agreement with 2.041%;radial dose functions with FLUKA for distances ranging from 0.5 cm to 10 cm, the deviation was less than 5%.Therefore the FLUKA code can be used to calculate the dosimetric characteristics of seed sources. |
