Abstract: A scintillator module includes a substrate, a columnar scintillator crystal layer formed on the substrate, and a non-adhesive moisture-proof member having a given hardness and opposing a crystal growing side of the columnar scintillator crystal layer. The moisture-proof member ensures a void between the moisture-proof member and individual conic peak portions of columnar scintillator crystals forming the columnar scintillator crystal layer under vacuum sealing, and holds the columnar scintillator crystal layer in a moisture-proof state between a moisture-proof layer and the substrate.

Abstract: An electromagnetic radiation detector of an embodiment includes a first scintillation detector that detects incidence of electromagnetic radiation and includes a first scintillator that outputs photons in response to the incidence of electromagnetic radiation; a second scintillation detector that detects scattered electromagnetic radiation exiting from the first scintillation detector, the scattered electromagnetic radiation that occurs inside the first scintillation detector due to Compton scattering of the electromagnetic radiation; and a multi-channel analyzer that performs multi-channel analysis of a result of the detection by the first scintillation detector, the result being other than results of the detection, timing of which is considered to coincide with timing of the detection by the second scintillation detector.

Abstract: According to an embodiment, a scintillator module includes a moisture-proof welding layer and a resin case. The moisture-proof welding layer is formed of a material having a welding property and a moisture-proof property, and extends to a side surface of a fiber optic plate to cover, in a sealed state, a scintillator layer and a visible-light reflective layer laminated on the fiber optic plate. The resin case covers the moisture-proof welding layer while being pressed against the side surface of the fiber optic plate.

Abstract: An additive containing an ion as a luminescence center is added to alkali halide powder as a base material. Mechanical energy for applying an impact force, a shearing force, a shear stress, or a friction force is applied so as to grind or mix the alkali halide powder and the additive. The ion as the luminescence center is doped into the alkali halide as the base material so as to obtain alkali halide-based scintillator powder. With this process, the alkali halide-based scintillator powder can be manufactured at a room temperature in the atmospheric air without any complicated condition control or any process at a high temperature under high vacuum and a large-sized scintillator sheet can be produced.

Abstract: A thermal neutron detecting device comprises a scintillator unit including a scintillator layer and a nuclear capture reaction layer, and an optical sensor array unit. The scintillator layer emits light upon receiving incident gamma ray or charged particles. The nuclear capture reaction layer is laminated on a side of the scintillator layer on which the gamma ray or the charged particles are incident, and includes first cell regions and second cell regions two-dimensionally, dispersedly arranged along an incidence plane of the gamma ray or the charged particles. The first cell regions contain a 6Li compound as a nuclear capture reaction material yielding nuclear capture reaction with incident thermal neutrons to generate the charged particles. The second cell regions contain no nuclear capture reaction material. The optical sensor array unit is capable of detecting a quantity of the emitted light in association with each of the first and second cell regions.
