What is the recommended approach to contamination control in radiological work?

• A. Spread contamination intentionally
• B. Contain and prevent spread, and decontaminate as needed; report
• C. Ignore
• D. Do nothing

Answer: (B)

The main idea is to keep radioactive material from spreading and to restore a clean, safe state as quickly as possible. Containing contamination means creating barriers and controls so it can’t move to other surfaces, tools, or people. This includes using proper work zones, barriers, and personal protective equipment, plus careful handling and housekeeping to prevent cross-contamination.

Decontamination is applied when contamination is found. It involves surveying with appropriate detectors, removing or reducing surface contamination through cleaning or wiping, and, if needed, replacing heavily contaminated materials. The goal is to reduce potential exposure and prevent further spread, while preserving as much safety and work efficiency as possible.

Reporting is an essential part of the process. Documenting the event, notifying the supervisor, and following any required regulatory or internal procedures ensures that corrective actions are taken, dose records are updated, and lessons are learned to prevent recurrence.

Spreading contamination, ignoring the issue, or doing nothing would increase risk to workers and the environment and would not align with safe, responsible radiological work.
