Abstract: A machine for the reading of the degree of opacity or transparency of radiographic film (20) in which one places, inside a box-shaped structure (10), a source (70) generating an analyzing light beam and a photo-receiving device (80) to convert the light impulses passing through the film (20) into variable voltage electrical impulses which are then sent to an electromechanic transducer in order to design a graphic display of the degree of opacity or transparency of the film (20) during the longitudinal and transversal scanning by the afore-mentioned light source (70) and photo-receiving device (80). The radiographic film (20) to be analyzed is placed on the machine's upper surface (18) which is made of a transparent material.
