What is Radiographic Testing (RT)?

Radiographic Testing (RT) is a non-destructive testing (NDT) method that uses ionizing radiation, such as X-rays or gamma rays, to inspect materials and components for internal flaws and defects. The radiation passes through the object, and the variations in radiation intensity are captured on film or a digital detector. These variations reveal differences in material thickness and density, indicating the presence of cracks, voids, inclusions, or other anomalies. RT is commonly used in industries like aerospace, oil and gas, and manufacturing to ensure the integrity of welds, castings, and other critical components.
