Abstract: The stimulable phosphor panel includes a rigid substrate, a stimulable phosphor layer formed on the rigid substrate and a transparent moisture-resistant protective layer formed on the stimulable phosphor layer. The stimulable phosphor layer is housed and sealed in an airtight area formed between the rigid substrate and the transparent moisture-resistant protective layer. The panel further includes a buffer space communicating with the airtight area capable of expansion/contraction. The buffer space is defined by a recess formed in the substrate, a ventilation hole connecting the recess with the airtight area and being formed in the substrate, and a flexible sheet covering an opening of the recess. Or, the buffer space has a volume variable within a range from 1/10 to twice of a sum of a spatial volume of the airtight area and a volume of the buffer space at 1 atm.

Abstract: A stimulable phosphor panel comprises a substrate having rigidity, a stimulable phosphor layer, and a transparent water vapor proof cover, which are overlaid one upon another in this order. The stimulable phosphor layer is accommodated and sealed within an enclosed region, which is enclosed between the substrate and the transparent water vapor proof cover.

The transparent water vapor proof cover may be constituted of a deformable film, and the buffer space may be formed by the utilization of a certain area of the transparent water vapor proof cover.

Abstract: The stimulable phosphor panel includes a support having a substrate or the substrate and a sealing member, a stimulable phosphor layer formed on the substrate being the support through gas phase deposition, a moisture-proof protective layer for sealing the stimulable phosphor layer and a sealing adhesive layer for bonding an outer periphery of the moisture-proof protective layer to the support.

The producing method forms the stimulable phosphor layer on the support through gas phase deposition, forms the adhesive layer and bonds the moisture-proof protective layer to the support through the adhesive layer. The stimulable phosphor panel is capable of preventing deterioration of its characteristics due to moisture absorption over a long period of time.
