Abstract
Provided is radiation detection equipment including: a semiconductor radiation detector which has a semiconductor crystal made of thallium bromide; a capacitor which applies a voltage to the semiconductor radiation detector; and at least one DC power source which accumulates positive charges and negative charges in either of electrodes of the capacitor. Herein, a cathode and an anode in the semiconductor radiation detector are formed of at least one kind of a metal selected from gold, platinum and palladium. Further, the DC power source periodically reverses a voltage of accumulating the positive charges and a voltage of accumulating the negative charges in either of the electrodes of the capacitor per interval shorter than 10 min, thereby to apply the resulting voltage thereto.
