Radiation detector and radiation detection apparatus

Abstract

Provided are a radiation detector and a radiation detection apparatus in which the efficiency of detecting radiation is enhanced by increasing a portion capable of detecting radiation. A radiation detector (1) includes a semiconductor part (12) having a plate-like shape, the semiconductor part being provided with a through hole (11) penetrating the semiconductor part (12), one surface of the semiconductor part (12) being an incident surface (121) for radiation. The semiconductor part (12) has a sensitive portion (18) capable of detecting incident radiation, the sensitive portion (18) including an inner edge (122) of the incident surface (121).
