"Notable" means the initial NRC report indicated at least one of: fire involvement, an evacuation, an injury, a fatality, or a transportation corridor (road, rail, waterway, or air) closure. Everything else is "routine" — real, and included in the totals above, but not individually described. Drill/exercise calls are excluded entirely from this page.
This page reflects initial, self-reported notifications made to the National Response Center. NRC's own published data explicitly describes these as reports that have not been validated or investigated by a federal or state response agency — they are not confirmed findings. For the full, unfiltered public dataset, see the National Response Center. For more on what "self-reported" and "unvalidated" mean in practice, see our Health & Environmental Data guide.
