PURPOSE:To facilitate the contrast of an image, by simultaneously recording a transmitted image by X-rays or gamma-rays and that by a neutron on one color film. CONSTITUTION:A scintillator 2 emitting red light upon response to X-rays or gamma-rays, a color film 3 and a scintillator 4 emitting blue light upon response to a neutron are received in a cassette 1 in a superposed state. Collimated neutron flux 6 and X-ray flux or gamma-ray flux 7 are incident to a specimen 5 and transmitted beam is allowed to irradiate the cassette 1. When the color film 3 is developed, an image, wherein a part through which X-rays or gamma-rays were transmitted is red and a part through which a neutron was transmitted is blue, can be obtained. Both transmitted parts show a color mixture corresponding to the degree of transmitting quantities. By interposing a red or blue filter if necessary, an image only of one radiation source can be discriminated. |
