Abstract
According to one embodiment, a radiation detector includes a stacked body. The stacked body includes a first scintillator layer, a first conductive layer, a second conductive layer and an organic semiconductor layer. The second conductive layer is provided between the first scintillator layer and the first conductive layer. The organic semiconductor layer is provided between the first conductive layer and the second conductive layer. The organic semiconductor layer includes a first element. The first element includes at least one selected from the group consisting of boron, gadolinium, helium, lithium, and cadmium.

A radiation detector, comprising:
- a stacked body comprising
- a first scintillator layer,
- a first conductive layer,
- a second conductive layer provided between the first scintillator layer and the first conductive layer, and
- an organic semiconductor layer comprising a first element and being provided between the first conductive layer and the second conductive layer, the first element comprising at least one selected from the group consisting of boron, gadolinium, helium, lithium, and cadmium,
- wherein
- a density of the first scintillator layer is higher than a density of the organic semiconductor layer, and
- a ratio (t1/t2) of a first thickness of the first scintillator layer (t1) to a second thickness of the organic semiconductor layer (t2) is 0.1 or less.
