PURPOSE: The titled screen, prepared by forming a fluorescent substance layer consisting of a binder obtained by dispersing radiatin sensitizing fluorescent substance particles in a support consising of a film of a resinous material containing a white pigment kneaded therein, and having improved sensitivity, flexibility and mechanical strength.

CONSTITUTION: A radiation sensitized screen prepared by forming a radiation sensitizing fluorescent substance layer consisting of a binder of preferably a nitocellulose and/or linear polyester containing dispersed particles of a radiation sensitizing fluorescent substance, preferably particles of an alkaline earth metallic fluorohalide type fluorescent substance, activated with bivalent europium, and capable of exhibiting the light emission in the near-ultraviolet or visible region, on a support consisting of polyethylene terephthalate containing a white pigment, preferably anatase type titanium dioxide, kneaded therein. The content of the white pigment in the above-mentioned support is preferably 0.1W10.0mg/cm2, particularly preferably 0.5W5.0mg/cm2, based on the surface area of the support.
