Which NDT method uses X-ray to show imperfections?

Explanation:
Radiographic testing uses X-rays to reveal internal defects. As X-rays pass through a material, they are absorbed differently by various features; defects like cracks, porosity, or inclusions alter the transmission and create contrast on a detector or film, showing internal imperfections. This is distinct from other methods: Ultrasonic testing uses high-frequency sound waves to detect internal features via echoes, Magnetic Particle Testing looks for surface and near-surface defects using magnetic fields and iron particles, and Penetrant Testing uses a dye that seeps into surface-breaking flaws and is then drawn out to reveal them. Because the description specifies using X-ray to show internal imperfections, radiographic testing is the method in question.
