Out‐of‐field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams
The four extended-range instruments provide reliable and consistent results, whereas the conventional rem counter underestimates H*(10) in a neutron field with a large high-energy component. FLUKA and MCNP provide consistent predictions, within a factor of 1.6 for the downstream position and lower differences in the other cases, and are in agreement with the experimental data. It was found that under certain conditions neutrons do not represent the only secondary radiation field to be monitored; the presence of charged particles affects the performance of moderator-type neutron detectors.
