A radiation image storage panel comprises at least a substrate and a phosphor layer overlaid upon the substrate. The phosphor layer contains a binder, a phosphor, and at least one kind of organic phosphorus compound represented by Formula (1):in which R represents an alkyl group, an aryl group, or a heterocyclic group, which may be optionally substituted by a substituent;M represents a hydrogen atom, an alkali metal, or -N+(R1)4, where R1 represents an alkyl group having at most two carbon atoms; andn represents an integral number of 1 or 2.The radiation image storage panel exhibits enhanced dispersibility of phosphor particles and a high sensitivity and yields little noise.
