Difference between radioactive material and contamination?

Difference between radioactive material and contamination?

• A. Radioactive material is located in an undesired location
• B. Radioactive material is inside its normal containment; contamination is in an undesired location.
• C. Radioactive material can never be contaminated.
• D. Radioactive material and contamination are the same concept.

Answer: (B)

Radioactive material refers to the substance that emits radiation, and it is safe and controlled when it stays inside its intended containment (shielded containers, glove boxes, or sealed sources). Contamination means that some of that radioactive material is outside its proper place—in an undesired location such as on a surface, on clothing, skin, or equipment. The key idea is that containment keeps the material where it belongs, while contamination is the unintended spread or deposition of that material elsewhere. Contamination creates exposure risk because it can be transferred, inhaled, ingested, or spread to other areas, which is why workers perform decontamination, use monitoring swipes, and follow spill control procedures.
