Abstract:
1. A radiological image conversion panel provided with a phosphor containing a fluorescent material that emits fluorescence by radiation exposure, wherein the phosphor comprises a columnar section formed by a group of columnar crystals which are obtained through columnar growth of crystals of a fluorescent material, and a non-columnar section, the columnar section and the non-columnar section are integrally formed on a support to overlap in a crystal growth direction of the columnar crystals in an order of the non-columnar section and the columnar section, the thickness of the non-columnar section along the crystal growth direction is non-uniform throughout the non-columnar section, the difference between the maximum thickness and the minimum thickness in the central region of the non-columnar section is less than the difference between the maximum thickness and the minimum thickness in the peripheral region of the non-columnar section, a diameter of each crystal constituting the non-columnar section is 0.5 μm or more and 7.0 μm or less, the crystals of the non-columnar section irregularly overlap, and some crystals thereof are fused to each other in a thickness direction or an in-plane direction, and the non-columnar section includes a non-crystalline part.
