Abstract |
|
|
| This work aims to study the influence of cross sections data, available in BEAMnrc /DOSXYZnrc Monte Carlo code, on the dosimetric calculations such depth dose and beam dose profiles. A SATURNE43 Linear accelerator has been modeled to simulate a 12 MV photon beam for a square open field of 10×10 cm². Gamma index criteria was used to analyze the MC results and measured ones, which was fixed within 1.5% -1 mm accuracy. The obtained results showed that the depth dose curves and beam profiles are less sensitive to photon and Bremsstrahlung cross section data.
