PROBLEM TO BE SOLVED: To provide a radiation sensitizing screen simultaneously showing high sensitivity and excellent reflection sharpness. SOLUTION: A radiation sensitizing screen for front side and an assembly using this sensitizing screen are obtained in such a way that a light reflecting layer, a fluorescent material layer, a surface protecting layer are formed on a supporting material in order, the light reflecting layer contains titanium dioxide powder having a mean particle size of 0.1-0.5μm, a volume filling ratio of 25-75%, and has a thickness of 15-100μm, the fluorescent material layer contains a fluorescent material showing main emission in the longer wave length side than a wave length of 430nm, and has a thickness of 40-120μm. |
