Radiation image conversion panel and manufacturing method thereof

摘要

A radiation image conversion panel which is provided with a stimulable fluorescent substance layer containing a stimulable fluorescent substance layer containing a stimulable fluorescent substance formed by a gas phase accumulating method on a support, wherein said stimulable fluorescent substance layer is constituted on a columnar crystal structure, and slopes D₁ and D₂₃ satisfy 0°<=|D₁-D₂|<=40°, when acute angles formed by said radiation image conversion panel surface and normal lines passing through the center of said columnar crystals, with respect to columnar crystals at arbitrary two points in the radiation image conversion panel plane, are designated as slopes of columnar crystals, D₁ and D₂.
