Why must contamination be controlled?

• A. It could be spread to places away from plant, like car, or home, or public places
• B. It cannot be detected by PCM
• C. It could cause contamination to vanish
• D. It could increase radiation exposure inside the plant only

Answer: (A)

Contamination must be controlled because radioactive material can easily be carried outside the plant by people, clothing, tools, or equipment. Even a tiny amount can hitch a ride into cars, homes, and public places, exposing others and creating opportunities for cross-contamination. Keeping contamination contained within the controlled area and promptly removing it protects workers, family members, and the public, and prevents the spread of contamination to the environment. It’s not about whether a detector can catch it, nor about contamination simply vanishing on its own, and it isn’t correct to say the risk is limited to increased exposure inside the plant. The real danger is off-site spread if containment isn’t maintained.
