PURPOSE:To obtain a sharp radiation image with high sensitivity by dispersing phosphor particles into binder layers on both sides of a visible light absorbing support to form a sensitized screen. CONSTITUTION:The first phosphor layer (a) contg. the same phosphor or, preferably, a phosphor exhibiting fluorescence in the blue region, dispersed into the binder, and the second phosphor layer (a') contg. the same phosphor, or anohter phosphor exhibiting fluorescence in the green region and dispersed into the binder on both sides of the plastic film support (b) contg. a visible light absorbing material, preferably, such as carbon black, to form a radiation sensitized screen 5. The radiation image of the object 2 is photographed by arranging radiation photographic films 4, 4' on both sides of the screen 5, thus permitting image blurring due to crossover light to be prevented and a sharp radiation image to be obtained with high sensitivity, i.e., in a small radiation amt. |
