Abstract

　本発明は、反射層の反射率を向上させ、光伝達効率が向上したシンチレータパネル及び放射線イメージセンサを提供する。この手段として、放射線を光に変換するシンチレータ層と、シンチレータ層を支持するための放射線透過性基板と、前記シンチレータ層で変換された光を外部へ出射するための反射層と、第１誘電体層と、第２誘電体層とを備えたシンチレータパネルにおいて、前記各層を、該放射性透過性基板から、該反射層、該第１誘電体層、該第２誘電体層、該シンチレータ層の順に配置し、かつ、該第１誘電体層の屈折率が該第２誘電体層の屈折率より小さいことを特徴とするシンチレータパネル及び放射線イメージセンサを特徴とする。
