Abstract
A scintillator panel includes a substrate made of an organic material, a barrier layer formed on the substrate and including thallium iodide as a main component, and a scintillator layer formed on the barrier layer and including cesium iodide as a main component. According to this scintillator panel, moisture resistance can be improved by providing the barrier layer between the substrate and the scintillator layer.
Claims5
A radiation detector comprising:
- a substrate made of an organic material;
- a barrier layer formed on a main surface of the substrate and including thallium iodide as a main component;
- a scintillator layer formed on the barrier layer and constituted of a plurality of columnar crystals including cesium iodide with thallium added thereto as a main component;
- a sensor panel including a photo-detection surface provided with a photoelectric conversion element receiving light generated in the scintillator layer;
- and
- a fiber optical plate disposed between the scintillator layer and the sensor panel, and configured to optically connect the scintillator layer and the sensor panel.
