Abstract
To obtain a neutron detector capable of measuring high dose neutrons with high neutron/gamma-ray discrimination ability and high efficiency. A scintillatorhas a layered structure in which a phosphor layerand a light transmission layerare alternately laminated in z direction. The phosphor layeris made of a phosphor material emitting fluorescent light by absorbing neutrons, the material being, for example, a scintillator material used in neutron detectors having already been known. The light transmission layeris made of a material highly transmitting fluorescent light emitted by the phosphor material and only slightly absorbing neutrons. In the scintillator, when neutrons and gamma-ray photons enter it, luminescence intensity (pulse height) due to neutrons is significantly different from that due to gamma-ray photons. It makes it easy to discriminate between outputs due to the two kinds of radiations.
