<p>PURPOSE:To obtain a film so designed as to be reinforced with neither irregularity in the transmission factor of X-rays nor reduction in the absolute quantity of transmitted X-rays by integrating a reinforcement made of the same material as that of a film body with the film body on one side face of the film body made of a material which transmits X rays. CONSTITUTION:One side face of a film body 14 made of a material which transmits X-rays has a reinforcement 15 made of the same material as that of the film body 14 integrated with the film body 14. For example, an X-ray transmitting film 13 has a film body 14 formed rectangularly: this film body 14 is made of Ba that is a material of high transmission factor to X-rays, and is provided with a reinforcement 15 integrated with the film body 14; the reinforcement 15 consists of a frame member 16 installed along the periphery of the film body 14 by Be that is the same material as that of the film body 14 and a partition member 17 which separates the interior of the frame member 16 into a plurality of triangular regions. Swinging in the direction of arrow Z enables irradiation of a predetermined range with X-rays.</p> |
