Scintillator panel, radiation detector, and method for manufacturing the same |
摘要 |
Provided are a scintillator panel and a radiation detector which give a radiation image reduced in sensitivity unevenness and sharpness unevenness. Also provided are processes for producing the scintillator and the detector. The scintillator panel comprises a support and, deposited thereon, a phosphor layer comprising columnar crystals of a phosphor which have been formed by the vapor deposition method. The panel is characterized in that the columnar crystals of a phosphor comprise cesium iodide (CsI) as a base ingredient and thallium (Tl) as an activator ingredient and have, in a root part thereof, a layer containing no thallium, and that the coefficient of variation in thallium concentration in the plane of the phosphor layer is 40% or less. |
