What is industrial radiography?
Industrial radiography is a method of testing hidden shortcomings and defects in various types of materials with X -ray or gamma radiation. Industrial radiography is similar to medical X -ray technology in that the film records an image of an item located between it and the radiation source. The penetration nature of radiation creates a clear image of the internal structure of the material with any density anomalies such as cracks that are clearly visible. This “hidden view” characteristic of industrial radiography makes it a non -destructive test vehicle to check working parts for wear and newly produced items for uniformity and possible defects. Although the sources of radiation used in radiography are generally no health risks, relevant safety measures should always be followed. As cutting of newly welded parts for inspection of welding integrity, it is somewhat counterproductive, for example, industrial radiography is an attractive choice for non -destructive diagnosis. This technology can beé use in construction to find reinforcement or pipes in concrete structures before persecution or cutting. It is even used as a safety assistance in scanning closed containers for smuggling, weapons or stWawayys.
The basic principle of the process is quite simple and common for all radiographic applications. The radiation from the controlled source can penetrate the test item and exhibit a specially formulated film. When the radiation passes through the item, its part is absorbed by the molecular structure of the material. The amount of absorbed radiation depends on the density and composition of the material. Simply put, the amount of radiation that goes through the item to expose the film depends on the density of the material.
as cracks, cracks and pockets in the material are obviously different densities, they will be characterized by different exposure values, because more or less radiation penetrates during the exposure at these points. ThatIt essents a very accurate image of the internal structure of the item. Objects located in an enclosed space also appear as anomalies when exposed to radiation, allowing examination scanning without opening the container. Industrial radiography can be used to scan a wide range of materials, including metals, ceramics, concrete, masonry, plastic, wood and organic fibers.
radiation sources for industrial radiography depend on the process used. Betatrons and linear accelerators are usually used to generate X-ray photon and radioactive isotopes such as Caesium-137, Cobalt-60 and Iridium-192, are used to generate gamma radiation. Although these radiation sources are considered safe, operators should always strictly complain all safety measures specific to the equipment used.
