Radiography Testing (RT): The Pillar of Industry Quality Assurance
Where structural integrity is at the top of an industry's agenda, the assurance that materials and components are totally free from internal defects is a bare minimum. Radiography Testing (RT) , as a method of Non-Destructive Testing (NDT), comes into play here. Just as medical X-rays enable doctors to x-ray bones to identify fractures, RT enables engineers and inspectors to look inside materials to identify flaws and defects without destroying the object itself. In aerospace and construction, manufacturing and oil & gas, RT is now an important quality control and safety inspection tool. Understanding Radiography Testing: The Science Behind It The principle of Radiography Testing is differential radiation absorption by materials. Focusing X-rays or gamma rays onto a target, areas of varying thickness and density absorb the radiation variably. The difference is measured by a detector, one that used to be photographic film or digital imaging equipment, and it forms an image ...
