Radiography

Radiography inspection, a type of Non-Destructive Testing (NDT), uses X-rays or gamma rays to detect internal and surface flaws in materials and components without causing damage to the object being tested. This technique provides a permanent record of the inspection, reveals both internal and external imperfections like cracks or porosity, and can be used on a variety of materials and geometries. However, it requires skilled personnel, specialized equipment, and strict safety protocols to manage the risks of radiation exposure, and its effectiveness can be limited by the orientation of the flaw and the complexity of the component
