Radiation detection equipment and nuclear medicine diagnosis device

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.

Dependencies are inferred from the claim text.
