X-ray testing can detect which types of defects?

• A. Portable
• B. Detects internal and surface defects
• C. Hidden / obstructed parts can be inspected
• D. Permanent record obtained

Answer: (B)

X-ray testing reveals flaws by showing how X-rays are attenuated as they pass through a material. Defects disrupt the normal flow of X-rays, so the radiograph highlights anomalies inside the part as well as features that reach the surface. This means it can detect internal flaws such as cracks, porosity, voids, and inclusions, and it can also reveal surface defects that extend to or are visible at the surface. The focus here is on the types of flaws, not on equipment portability or documentation, so the key point is that X-ray testing identifies both internal and surface defects.
