RADIATION MONITOR AND RADIATION MEASUREMENT METHOD

To provide a radiation monitor that can remotely and simply measure a space dose rate, charged particle and neutron discriminately.SOLUTION: A radiation monitor 100 comprises: a radiation detection unit 10 that detects radiation; and an optical fiber 20 that transports a photon discharged from a light emission element of the radiation detection unit. The radiation detection unit 10 comprises: a first light emission element 1 that generates the photon with respect to the incident radiation; a compound part 3 that has a compound generating a charged particle due to a nuclear reaction with the incident neutron; and a second light emission element 2 that, between the first light emission element and the compound part 3, generates photon with respect to the radiation.SELECTED DRAWING: Figure 1 【課題】遠隔で簡易に、空間線量率、荷電粒子及び中性子を弁別して測定できる放射線モニタを提供する。【解決手段】放射線モニタ１００は、放射線を検知する放射線検知部１０と、放射線検知部の発光素子から放出された光子を伝送する光ファイバ２０と、を備え、放射線検知部１０は、入射した放射線に対して光子を生成する第１発光素子１と、入射した中性子との核反応により荷電粒子を生成する化合物を有する化合物部３と、第１発光素子と化合物部３との間に、放射線に対して光子を生成する第２発光素子２と、を具備する。【選択図】図１
