Abstract :
Storage phosphors such as KCl:Eu+ with low gamma-ray sensitivity were applied to detection of fast neutrons using polyethylene (PE) sheets as a proton generator that were set in front of the phosphors. The maximum PSL yields were obtained at a PE thickness of 3 mm when the neutron energy was 14.8 MeV. These experimental results well agreed with those by Monte Carlo simulation using PHITS code. Estimated PSL yields by gamma-ray associated with fast neutron fields were negligible. This combination use of such phosphors and PE sheets will be usable for fast neutron monitoring or imaging in a high gamma-ray fields.
