摘要： In an X-ray line sensor 1, a scintillator layer 24 that absorbs X-rays in a low-energy range and emits light and a scintillator layer 26 that absorbs X-rays in a high-energy range and emits light are brought in contact with each other, and further, the thickness of the scintillator layer 24 on the front side is thinner than that of the scintillator layer 26 on the rear side. These make the amount of mismatch small between a light emitting position P1 in the scintillator layer 24 and a light emitting position P2 in the scintillator layer 26 to X-rays in the low-energy range and X-rays in the high-energy range entered at the same angle from the front side, so that at this time, light emitted by the scintillator layer 24 and light emitted by the scintillator layer 26 are detected by a photo-detecting section 16 and a photo-detecting section 23 facing each other. Thus, mismatch between an X-ray transmission image in the low-energy range and an X-ray transmission image in the high-energy range obtained simultaneously can be prevented.

摘要： A radiation detection device includes a first radiation detector that is positioned on the upstream side of a radiation incident direction and detects radiation in a low-energy range, and a second radiation detector that is positioned on the downstream side and detects radiation in a high-energy range. In such a configuration, a pixel width p1 of pixels 13 in an imaging element 12 in the first radiation detector and a pixel width p2 of pixels 23 in an imaging element 22 in the second radiation detector are set to be different in width from each other by considering the distance Δd between the imaging elements, and the pluralities of pixels in the first and second imaging elements 12 and 22 are respectively divided into pluralities of pixel units, and a pixel unit width w2 in the second imaging element 22 is set to be larger than a pixel unit width w1 in the first imaging element 12. Accordingly, a dual-energy radiation detection device capable of reducing deviations between images acquired with two-stage radiation detectors is realized.
