Background

Different sorts of interactions may result in the production of secondary radiation when proton interact with human tissues. One of the most dangerous is the neutron. These neutrons correlated with the proton energy, type of the material and beam delivery technique[1]. The intensity of neutrons will increase while the proton energy increases. Where as Passive scattering mode emits more secondary neutrons than pencil beam [2]. Therefore, monitoring and tracking the dose distribution of primary and associated secondary radiation is highly recommended to verify delivering the prescribed dose.

Coating a Si detector with high cross-section converter materials for thermal neutron detection such as 6Li will make the detector sensitive to detecting thermal neutrons by capturing them inside these converters and the resulted fission products produced (Alpha at 2.05 MeV and Triton at 2.73 MeV) will be emitted in opposite directions from the converter material. These fission products could be measured through the Si sensors [3][4].
