PROBLEM TO BE SOLVED: To provide a phosphor screen and a radiation detection device for acquiring X-ray energy information with high accuracy.SOLUTION: A radiation detection device 3 has a radiation detector array 5 in which two or more radiation detectors 50 for converting radiation energy into an electrical charge are arranged in longitudinal and crosswise directions, with one kind or two or more kinds of radiation absorption filters arranged in a two-dimensional cyclic pattern on the radiation incident side. For example, two or more kinds of stripe-shaped radiation absorption filters 4A, 4B are arranged diagonally to each other.SELECTED DRAWING: Figure 3 |
