Abstract
A radiation film comprises a substrate and emulsion layers overlaid on opposite surfaces of the substrate. The radiation film is sandwiched between two radiation intensifying screens having different radiation energy absorption characteristics. Each of the emulsion layers has a sensitivity corresponding to the emission spectrum of its adjacent radiation intensifying screen. The emulsion layers form different colors in the radiation film after the radiation film has been developed. A removable light blocking layer is located between the substrate and each of the emulsion layers. The radiation film enables two kinds of images to be recorded with different radiation energy characteristics on a single radiation film, such that the image quality may not become bad due to cross-over light.
