Proton therapy causes less damage to healthy tissue compared to other radiation therapies; however, the possible damage caused by secondary, fast neutrons is almost unknown. In some simulations, neutron dose amounts to 10% of the proton dose; therefore, a real-time visualization of the neutron dose is needed. We have developed a neutron camera that can visualize the direction and intensity of fast neutron sources. The camera consists of eight units of a plastic scintillator (EJ-299-34) coupled with a compact PMT (R9880U). We demonstrate that a 252Cf neutron source is correctly imaged with an angular resolution of 15.5 deg (FWHM). In addition, fast neutrons emitted from the brass block irradiated by 70 MeV were successfully monitored in real time. Finally, we present our prospects for future clinical applications.
