Abstract
Disclosed is a radiation image storage panel having a stimulable phosphor layer including a stimulable phosphor which absorbs both a radiation in a wavelength shorter than 250 nm and ultraviolet rays in a wavelength of 250-400 nm, then which stores their energies, and which emits the energies as luminescence when it is exposed to irradiation of a visible light or an infrared ray; and also including a phosphor which spontaneously emits ultraviolet rays in a wavelength of 250-400 nm when it is excited by a radiation in a wavelength shorter than 250 nm. Also there disclosed is another radiation image storage panel having separately a stimulable phosphor layer and an ultraviolet ray emitting phosphor layer including the phosphor which emits ultraviolet rays in a wavelength of 250-400 nm when it is excited by a radiation in a wavelength shorter than 250 nm.
