RADIATION DETECTOR

To provide a radiation detector that can reduce noise.SOLUTION: A radiation detector relating to an embodiment of the present invention comprises: a housing; an array substrate which is arranged in the housing and includes a plurality of detecting units for detecting radiation rays directly or in association with a scintillator; a circuit board which is arranged in the housing and is electrically connected to the array substrate; and a conductive part which is arranged in the housing and is arranged between a membrane-like ground mounted on the circuit board and a conductive plate arranged in the housing. The conductive part having conductivity includes a softer material than the material of the ground.SELECTED DRAWING: Figure 1 【課題】ノイズの低減を図ることができる放射線検出器を提供することである。【解決手段】実施形態に係る放射線検出器は、筐体と、前記筐体の内部に設けられ、放射線を直接的またはシンチレータと協働して検出する複数の検出部を有するアレイ基板と、前記筐体の内部に設けられ、前記アレイ基板と電気的に接続された回路基板と、前記筐体の内部であって、前記回路基板に設けられた膜状のグランドと、前記筐体に設けられ、導電性を有する板状体と、の間に設けられた導電部と、を備えている。前記導電部は、導電性を有し、前記グランドの材料よりも柔らかい材料を含んでいる。【選択図】図１
