摘要：
Provided is a neutron capture therapy system and a gamma ray detector for neutron capture therapy capable of detecting gamma rays with high accuracy even in a high-intensity neutron field. A neutron capture therapy system (1) includes a neutron ray generating unit (10), an irradiated body placing unit (20) on which a patient (H) (irradiated body) is placed, and a gamma ray detecting unit (30) that detects gamma rays (G) emitted from the patient (H) (irradiated body) . The gamma ray detecting unit (30) includes an emission part (31) that emits light or electrons as the gamma rays (G) are incident thereon, an amplification part (32) that amplifies and outputs the light or the electrons emitted from the emission part (31), a first neutron ray shielding part (33) formed of a substance containing 6-lithium, and a second neutron ray shielding part (34) formed of a light element. The first neutron ray shielding part (33) is provided so as to cover at least a surface opposite to an adjacent surface (31a) adjacent to the amplification part (32), among surfaces of the emission part (31).本發明提供一種在高強度的中子場中亦能夠高精度地檢測伽瑪射線之中子捕獲治療系統及中子捕獲治療用伽瑪射線檢測器。中子捕獲治療系統(1)具備：中子束生成部(10)；載置患者(H)(被照射體)之被照射體載置部(20)；及檢測從患者(H)(被照射體)放出之伽瑪射線(G)之伽瑪射線檢測部(30)，伽瑪射線檢測部(30)具有：放出部(31)，藉由入射伽瑪射線(G)而放出光或電子；放大部(32)，放大從放出部(31)放出之光或電子而輸出；第1中子束屏蔽部(33)，由含有鋰6(6Li)之物質形成；及第2中子束屏蔽部(34)，由輕元素形成，第1中子束屏蔽部(33)設置成至少覆蓋放出部(31)的面當中的與放大部(32)的相鄰面(31a)相反的一側的面。
