PROBLEM TO BE SOLVED: To shorten an interruption time of radiation measurement caused at the time of canceling polarization in a nuclear medicine diagnosis device using a semiconductor radiation detector. SOLUTION: This device is equipped with a capacitor 13 for applying a voltage to the semiconductor radiation detector 14 for detecting a radiation from a specimen, the first constant current means 15 for allowing a charge current to the capacitor 13 to flow, the second constant current means 16 for allowing a discharge current from the capacitor 13 to flow. The device may be optionally equipped with a capacitor for applying a voltage to the semiconductor radiation detector, the first resistor for allowing a charge current to the capacitor and a discharge current therefrom to flow, and the second resistor connected in parallel to the first resistor when charging or discharging the capacitor.
