Abstract:
1. 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 a radiation converting film 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 average crystal diameter of the columnar crystals located on a peripheral measuring area that has a maximum width of 1 mm or less is 1.3 times or more larger than an average crystal diameter of the columnar crystals located on a central measuring area that includes the gravity center position and has a maximum width of 1 mm or less, said peripheral measuring area locating at a position where a distance from the gravity center position is 60% of a minimum distance from the gravity center position to an edge of said film forming region.
