What are indicators of a possible radiological incident include?

Indicators of a possible radiological incident include unusual levels of radiation detected by monitoring equipment, reports of individuals experiencing unexplained health effects such as nausea or skin burns, and sightings of suspicious materials or devices near sensitive locations. Additionally, unexpected emergency response activities, such as the deployment of hazmat teams or evacuation orders, can signal a potential radiological threat. Public alerts or warnings from authorities about radiation exposure can also serve as critical indicators.
