Radiation image storage panel

摘要

A radiation image storage panel has a phosphor layer composed of energy-storing phosphor particles and a polymer binder and satisfies the following conditions; T₁xd>=660; T₂xd>=660; D>=3.4 [T₁ is a transmittance (%) of the phosphor layer at a peak wavelength of a stimulation spectrum of the phosphor particles; T₂ is a transmittance (%) of the phosphor layer at a peak wavelength of a stimulated emission spectrum of the phosphor particles; d corresponds to a value of 10,000xW/p (W is a weight of the phosphor particles in a unit area of the phosphor layer expressed by mg/cm² and rho is a density of the energy-storing phosphor expressed by g/cm³]; and D is a density of the energy-storing phosphor particles contained in the phosphor layer expressed by g/cm³].
