Patent ID: 7608835

Claim:
A radiation image converting panel comprising: a support body having a first main surface and a second main surface opposing said first main surface; and an radiation converting film doped with Eu and provided on a film forming region which exists within said first main surface of said support body and includes at least a gravity center position of said first main surface, said radiation converting film being comprised of columnar crystals which are coincident or tilted at a predetermined angle with respect to a normal direction of said first main surface, wherein, in said film forming region of said first main surface, an Eu concentration of said radiation converting film, located on a peripheral area sandwiched by an edge of said film forming region and a circumference of a reference circle around the gravity center position, is set higher than an Eu concentration of said radiation converting film located on the gravity center position, said reference circle having a radius of 40% or more but 80% or less of a minimum distance from the gravity center position to the edge of said film forming region.
