Both Nondestructive Testing and Radiographic Testing are essential methods for inspecting materials without damage. Nondestructive Testing encompasses various techniques, including radiography, ultrasonic, magnetic particle, and dye penetrant testing. Radiographic Testing specifically uses X-rays or gamma rays to detect internal flaws. While radiography is a subset of Nondestructive Testing, Nondestructive Testing offers a broader range of inspection methods suitable for different applications and environments.
