<p>This radiation image pickup system is provided with a radiation source and a radiation image detecting device. The radiation image detecting device has a solid-state detector and a wavelength conversion layer disposed therein in this order from the radiation input side. The wavelength conversion layer detects inputted radiation that has passed through the solid-state detector, and converts the radiation into visible light. The solid-state detector detects the visible light and generates image data. The wavelength conversion layer is a single phosphor layer wherein at least first phosphor particles having a first average particle diameter, and second phosphor particles having a second average particle diameter smaller than the first average particle diameter are mixed in a binder. The weight of the first phosphor particles per unit thickness of the wavelength conversion layer is gradually reduced toward the side away from the solid-state detector.</p> |
