PROBLEM TO BE SOLVED: To provide a radiation detector which can detect radiation with a high count rate and collect energy information as well. SOLUTION: An X-ray detector 3 comprises a matrix M made of silicon, which is a semiconductor, and first to fourth electrodes 21 to 24 for outputting a current developed in the matrix M. The matrix M is formed in a plate shape extending in the incident direction of filtered X-rays and is provided with a ground side electrode E on its one end. The first to fourth electrodes 21 to 24 are arranged in order along the incident direction of the filtered X-rays on the top side of the matrix M. COPYRIGHT: (C)2007,JPO&INPIT
