Abstract
Official abstract text for this publication.
A scintillator panel includes a substrate, a resin protective layer formed on the substrate and made of an organic material, a barrier layer formed on the resin protective layer and including thallium iodide as a main component, and a scintillator layer formed on the barrier layer and including cesium iodide with thallium added thereto as a main component. According to this scintillator panel, moisture resistance can be improved due to the barrier layer provided therein.
First claim
Opening claim text (preview).
What is claimed is: 1. A radiation detector comprising: a sensor substrate including an organic material as a main component; a resin protective layer formed on the sensor substrate and made of an organic material; a barrier layer formed on the resin protective layer and including thallium iodide as a main component; and 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, wherein the sensor substrate has a photo-detection surface provided with a photoelectric conversion element receiving light generated in the scintillator layer. 2. The radiation detector according to claim 1 , wherein the organic material included in the sensor substrate as a main component is any one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN) and polyimide (PI). 3. The radiation detector according to claim 1 , wherein the organic material forming the resin protective layer includes any one of a xylylene resin, an acrylic resin, a silicone resin, polyimide, a polyester resin, a siloxane resin and an epoxy resin. 4. The radiation detector according to claim 1 , further comprising: a protective film covering a front surface of the resin protective layer, side surfaces of the scintillator layer and a front surface of the scintillator layer. 5. The radiation detector according to claim 4 , wherein the protective film is formed by polyparaxylylene.
