PROBLEM TO BE SOLVED: To provide a radiation detector excellent in a measurement environment such as spatial radiation dosage, temperature and humidity.SOLUTION: A radiation detector 10 includes a cylindrical envelope 11 being a cathode in which ionization gas 13 reacting to radiation is sealed, an anode 14 which is arranged along a central axis of the envelope, and a connector 12 which is attached to one end of the envelope 11 to connect the cathode and the anode 14 to a signal cable 21 with a shield line. The connector 12 includes a conductive connector case 121 cylindrical one end of which is connected to the envelope 11 and the other end of which is connected to the shield line, a socket type connector conductor 122 which connects an anode terminal 14a and a core wire of the signal cable 21, and a housing insulator 123 which houses the connector conductor 122, is held inside the connector case 121 and consists of an inorganic insulator material. 【課題】 空間放射線量、温度、湿度などの測定環境に優れる放射線検出器を提供する。【解決手段】 放射線検出器１０は、放射線に反応する電離ガス１３が封入され、陰極になる筒状の外囲器１１と、その中心軸に沿って配設された陽極１４と、外囲器１１の一端に取り付けられ、陰極および陽極１４をシールド線付きの信号ケーブル２１に接続するコネクタ１２を備える。コネクタ１２は、筒状の一端が外囲器１１に接合されその他端がシールド線に接続される導電性のコネクタケース１２１と、陽極端子１４ａおよび信号ケーブル２１の芯線を接続するソケット型のコネクタ導体１２２と、コネクタ導体１２２を収容しコネクタケース１２１の内部に保持される無機絶縁体材からなる収容インシュレータ１２３を有する。【選択図】 図１
