X-ray inspection limitations are that it can locate flaws only at the surface.

• A. True
• B. False
• C. It can locate only deep flaws
• D. It cannot locate any flaws

Answer: (B)

X-ray inspection uses penetrating radiation to image the interior of a part, so it can reveal internal flaws such as porosity, cracks, and inclusions by showing density differences along the beam path. This means flaws buried inside the material can be detected, not just surface defects. Saying that X-ray inspection locates flaws only at the surface is not accurate. There are limitations—flaws must lie in the path of the X-ray beam and have enough contrast to be seen, and very thick or highly attenuating sections can mask defects—but the key idea is that internal flaws can indeed be found with X-ray inspection.
