The experiment was performed at room temperature, two methods of observations are done on High Silica Phenolic liner and the experiments are carried out as per specifications mentioned below: Technical parameters MACHINE METHOD ENERGY (kV) CURRENT(mA) TIME (min) FILM SFD Pantak(450kV) Normal 75 2.7 2 T200 2m Pantak(450kV) Tangential 85 2.7 2 T200 2m SFD: Source to Film Distance Normal Radiography schematic Block diagram Normal Radiography experimental setup Results and Discussions Normal Radiograph of High Silica Phenolic liner From the Radiograph, no defects are observed in normal method. As the defects are not in parallel to the direction of X-ray beam travel and therefore not detected by this method. Hence Tangential Radiography is conducted. …show more content…

Film Processing In the processing procedure, the invisible image produced in the film by exposure to X-rays, Gamma rays or light is made visible and permanent. Processing is carried out under subdued light of a color to which the film is relatively insensitive. The film is first immersed in a developer solution, which causes the areas exposed to radiation to become dark, the amount of darkening for a given degree of development depending on the degree of exposure. After development, and sometimes after a treatment designed to halt the developer reaction abruptly, the film passes into a fixing bath. The function of the fixer is to dissolve the darkened portions of the sensitive salt. The film is then washed to remove the fixing chemicals and solubilized salts, and finally is dried. Processing techniques can be divided into two general classes: "Manual Processing" and "Automated Film Processing". Automatic film processing machine (Kodak) Manual film processing setup INFRARED
