description PROBLEM TO BE SOLVED: To provide a radiation measuring apparatus, along with nuclear medicine diagnostic equipment using the same, for measuring with no polarization at a stable performance by preventing damage on an amplifier, with a shorter interrupted period in measurement. SOLUTION: A radiation measuring apparatus 11 includes: a semiconductor radiation detector 111 for detecting radiation; a capacitor 110 for applying a voltage to the semiconductor radiation detector; one or more DC power sources 101 and 102 which can accumulate positive electric charge and negative electric charge on one electrode of the capacitor; a constant current device 189 which causes a flow of a current from the DC power source to the electrode of the capacitor; and two or more switch devices 105 and 106 connected to a wiring for connecting the DC power source to the electrode of the capacitor. Pieces of nuclear medicine diagnostic equipment 600 and 700 include the radiation measuring apparatus 11. COPYRIGHT: (C)2011,JPO&INPIT
