What does contamination refer to in a radiological context?

• A. Radioactive material where it doesn't belong.
• B. Clean, properly placed radioactive material.
• C. Non-radioactive material inside a controlled area.
• D. Any material in a labeled container.

Answer: (A)

Contamination means radioactive material where it doesn't belong. It’s the unwanted presence of radioactive material on surfaces, equipment, clothing, or people, which can spread if it isn’t contained or cleaned up. This is what makes decontamination, monitoring, and proper containment important in radiological work. This isn’t about material that is clean and properly placed, nor about non-radioactive material in a controlled area. And while labeling helps prevent mix-ups, simply being inside a labeled container doesn’t by itself define contamination.
