If you observe a radiation spill, what is the first action you should take?

• A. Notify your supervisor immediately.
• B. Secure the area to prevent spread.
• C. Put on the appropriate PPE and begin containment.
• D. Contain the spill to prevent spread.

Answer: (A)

When a radiological spill is observed, the priority is to activate the official response by alerting supervision right away. This ensures trained personnel—such as health physics or the safety team—can assess the spill, classify its severity, and initiate the appropriate containment and decontamination procedures under proper radiological controls. Without prompt notification, the incident may go unmanaged, increasing exposure risk and the chance of spreading contamination. You’ll be guided on securing the area, donning the correct protective equipment, and carrying out containment only under established procedures. In short, informing the supervisor starts the safest, properly controlled response.
