SCINTILLATOR PANEL

摘要

Disclosed is a scintillator panel having improved luminance, which comprises a phosphor layer which emits light when irradiated with radiation, a substrate supporting the phosphor layer, and a protective film covering the phosphor layer and the substrate. This scintillator panel is characterized in that the phosphor layer is composed of two or more layers, and the average concentration of the activator relative to the phosphor in the outermost layer, which is expressed as B (mol%), and the average concentration of the activator relative to the phosphor in the other phosphor layers, which is expressed as A (mol%), satisfy the following formula (1). (Formula 1): 1.0 = B/A = 1000
