Abstract
A radiation detector includes a flexible substrate, plural pixels provided on the substrate and each including a photoelectric conversion element, a scintillator stacked on the substrate and including plural columnar crystals, and a bending suppression member configured to suppress bending of the substrate. The bending suppression member has a rigidity that satisfies R≥L−r/tan Φ+4r·{(L−r/tan Φ)−(d/2)}/d, wherein L is an average height of the columnar crystals, r is an average radius of the columnar crystals, d is an average interval between the columnar crystals, Φ is an average tip angle of the columnar crystals, and R is a radius of curvature of bending occurring in the substrate due to the weight of the scintillator.
