Industrial radiography is a non-destructive testing technique that uses radiation to inspect materials and structures for defects. It involves the use of X-rays or gamma rays to create images of the internal features of an object, such as welds, pipes, and metal components. This method helps ensure the integrity and safety of critical infrastructure. The process typically requires a radiographic film or digital detector to capture the radiation that passes through the object. By analyzing these images, inspectors can identify issues like cracks, voids, or corrosion, making industrial radiography essential in industries such as construction, manufacturing, and aerospace.
