Dose due to neutrons resulting from highenergy
linear accelerator is not detailed in routine treatment
planning, though this information is potentially
important for better estimates of health risks including
secondary cancers. In this study, the neutron contaminations
were evaluated in the patient-specific voxel phantom
for the treatment of prostate cancer using MCNP code. The
results showed that the neutron organ doses are independent
from the distance between studied organs and treatment
area, and unlike the photon dose, the neutron dose
distribution is almost homogeneous in the patient body.
