Abstract:
1. A radiation image detection device comprising: a wavelength converting layer for converting radiation into light, the wavelength converting layer being a single phosphor layer in which at least first phosphor particles and second phosphor particles are dispersed in a binder, the first phosphor particles having a first average particle diameter, the second phosphor particles having a second average particle diameter smaller than the first average particle diameter; and a solid state detector for detecting the light and thereby generating image data, the solid state detector and the wavelength converting layer being disposed in this order from a radiation-incident side on which the radiation from a radiation source is incident at the time of imaging; wherein, a weight of the first phosphor particles per unit thickness of the wavelength converting layer decreases with increasing distance from the solid state detector.
