Film radiography is a non-destructive technique used to evaluate any material or component’s internal structure using X-ray or cobalt-60. The aim of film radiography at Impartial Testing is to identify the flaws after inspecting types of machinery like valves or pressure vessels.
In this process, the test part’s placement is between the film and the source of radiation. After crossing the specimen, there is a process of capturing the absorption differences in photons’ form on the film. The location which gets darkened in the film shows defects. The film radiography is helpful in food inspection, aircraft maintenance recycling and other industrial purposes.
X-Ray
Film radiography is the NDT technique in which a beam of x-rays produced from a cathode or anode points towards an object or fabricated equipment for detecting any flaws in it. On the other side of the object, the detector is attached, which records the X-rays passing through the object.
Iridium-192
Iridium-192, a gamma radiation source, is the film radiography used in industries to detect structural damage of different metal equipment. Impartial Testing has skills in using Ir-192 radioisotope sources to perform industrial gamma radiography on materials such as castings, weld issues and forging. The techniques are portable as well as stationery.
Cobalt-60
For very thick components, Cobalt 60, another gamma radiation source, is used. It is helpful in typical industrial applications like gauging the thickness, levelling of various devices and such. Through film radiography, the isotope’s radiation helps detect structural flaws in different metal parts without resulting in any destruction.
