What should be the first action taken in case of a radiation exposure incident?

In the event of a radiation exposure incident, providing medical assistance if necessary is crucial as a first action. The health and safety of individuals potentially affected by radiation must take precedence. Assessing the situation for any immediate medical needs allows for rapid intervention to prevent harm to those exposed.

After ensuring that individuals receive any required medical attention, other procedures, such as notifying authorities or evacuating the area, can be implemented. Documenting the event is also important but typically occurs after initial medical needs are addressed. Therefore, prioritizing medical assistance ensures that any potential health risks are managed in a timely manner, which is essential in radiation safety practices.
