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 sensor panel including a panel front surface including a photo-detection region including a photo electric conversion element;
- a barrier layer formed on the panel front surface comprising thallium iodide as a main component;
- a scintillator layer formed on the barrier layer and including a plurality of columnar crystals comprising cesium iodide with thallium added thereto as a main component;
- and
- a sealing portion provided on a panel front surface, fixed to a surrounding region surrounding the photo-detection region, and covering the barrier layer and the scintillator layer.
