Abstract:
1. A radiation detector that detects radiation in a first energy range and radiation in a second energy range, comprising: a first photo detector having a first scintillator layer extending along a first direction, a first photo-detecting device extending along the first direction, and a first substrate provided with the first photo-detecting device, for detecting radiation in the first energy range; and a second photo detector having a second scintillator layer extending along the first direction, a second photo-detecting device extending along the first direction, and a second substrate provided with the second photo-detecting device, for detecting radiation in the second energy range, wherein direction of extension of the first substrate and direction of extension of the second substrate are identical to each other, in the direction of extension of the first substrate, one edge portion of the first substrate is located outside further than one edge portion of the second substrate, and in the direction of extension of the second substrate, the other edge portion of the second substrate is located outside further than the other edge portion of the first substrate.
