Radiation detector and radiation detection device

The invention discloses a radiation detector and a radiation detection device comprising the radiation detector. The radiation detector comprises a semiconductor crystal used for sensing radiation, a first anode arranged on the top surface the semiconductor crystal, a second anode arranged on the bottom surface of the semiconductor crystal, and one cathode on at least one side face of the semiconductor crystal. The semiconductor crystal comprises the top surface, the bottom surface and at least one side face. The radiation detection device comprises the radiation detector and a signal processing circuit. The radiation detector achieves the feature of singly-charged flexibility by utilizing the double-anode structure which is simple, and energy resolution is improved.
