Abstract:
(EN) This radiation measurement instrument (4) is equipped with a control unit (45) for determining whether a measurement instrument main body (46) which includes an ionization chamber (41), a current measurement unit (43) and a bias voltage application unit (44) is normal or not, on the basis of a charging current which flows through the ionization chamber (41) as a result of a bias voltage being applied, and is measured by the current measurement unit (43).
(FR) La présente invention concerne un instrument de mesure de rayonnement (4) comportant une unité de commande (45) pour déterminer si un corps principal d'instrument de mesure (46), qui comprend une chambre d'ionisation (41), une unité de mesure de courant (43) et une unité d'application de tension de polarisation (44), est normal ou non, sur la base d'un courant de charge qui circule à travers la chambre d'ionisation (41) suite à l'application d'une tension de polarisation, et est mesuré par l'unité de mesure de courant (43).
(JA) この放射線計測器(4)は、バイアス電圧が印加されることによって電離箱(41)に流れるとともに電流測定部(43)により測定された充電電流に基づいて、電離箱(41)、電流測定部(43)およびバイアス電圧印加部(44)を含む計測器本体部(46)が正常か否かを判断する制御部(45)を備える。
