What is the typical sequence of steps in the initial response to a radiological incident?

• A. Identify source, establish control zones, monitor dose, implement decontamination, use PPE, notify authorities, secure area, document and plan cleanup.
• B. Notify authorities, identify source, document and plan cleanup, monitor dose, decontamination, PPE, control zones, secure area.
• C. Decontaminate first, then identify source, establish control zones, monitor dose, use PPE, notify authorities, secure area, document and plan cleanup.
• D. Use PPE first, then identify source, establish control zones, monitor dose, decontaminate, notify authorities, secure area, document and plan cleanup.

Answer: (A)

The key idea is to quickly understand the radiological hazard and prevent its spread before taking corrective actions. Start by identifying the radioactive source so you know what you’re dealing with and what protective actions may be needed. This information guides how you set up the scene, so you can establish control zones that limit who can enter and help contain contamination. Once zones are in place, you measure the dose to gauge exposure levels and determine how long responders can work and what additional protections might be required. With the hazard characterized, you move to decontamination to physically remove radioactivity from people, equipment, and surfaces, which lowers exposure risk and prevents further spread. Protective equipment is then selected and used as appropriate for the situation. Authorities should be notified to ensure proper oversight, regulatory compliance, and access to additional resources. Securing the area prevents unauthorized access and maintains safety, and documenting actions while planning cleanup provides accountability and a clear path to complete remediation. Starting with identifying the source and establishing zones first sets up an effective, safety-first response that minimizes exposure and containment challenges.
