| dc.description.abstract | The BEAMnrc Monte Carlo package is used to simulate the 60Co beam from the \Theratron Equinox 80" 60Co radiotherapy unit. In modeling the 60Co unit a particular attention has been paid for the geometry and material construction of the 60Co source capsule, source housing, and the collimator assembly. The in uence of eld size on total photon spectra, scattered photon and electron spectra, (which is produced from the photon interaction with the materials surrounding the Cobalt source and collimator assembly), at the phantom surface (SSD equal to 80 cm) are studied. From our simulation the variation of total photon and scattered photon spectra with increasing eld size is caused by scattered photons from di erent parts of the 60Co radiothereapy unit. We also used BEAMnrc generated phase space les as beam source for DOSXYZnrc to calculate the percentage depth dose and compared with measured values | en_US |
