of cancers. However, the production of electrons as contaminants in the photon pathway
provides the necessity for research in this field. Methods: Using BEAMnrc code, a
Varian2100C/D accelerator head was simulated with 6 MV energy. Applying the advanced
techniques of the variance reduction, Depth Dose curves at the Isocenter were obtained and
compared to the measurements. We used DOSXYZ code to calculate the Percentage depth …
