Which of the following is an aspect of contamination control (RPD)?

• A. Restricting areas
• B. Preventing spread
• C. Decontamination
• D. All of the above

Answer: (D)

Contamination control involves a set of coordinated actions to prevent and remove radioactive contamination. Restricting areas limits who can move into potentially contaminated zones, reducing the chance that contamination is carried to clean areas. Preventing spread focuses on keeping contaminants from migrating through barriers, proper containment, and safe work practices so that a spill or diffuse contamination doesn’t spread. Decontamination is the process of removing contamination from surfaces, equipment, and personnel to restore a clean state and reduce residual risk. Because a complete contamination-control program relies on restricting access, preventing spread, and decontamination, all of these aspects are involved.
