What to Do Right Now

Select your crisis type to get immediate step-by-step guidance.

Radiation, detonation, or fallout

1

First 10 Minutes

  • Move indoors immediately — any building is better than outside
  • Go to the basement or center of a large building
  • Close all windows, doors, and fireplace dampers
  • Turn off fans, AC, and forced-air heating
  • Shower with soap and water if you were outside — do not scrub skin
  • Do not use conditioner — it binds radioactive particles to hair
2

First Hour

  • Stay indoors and away from windows
  • Listen to official emergency broadcasts
  • Seal gaps around windows and doors with tape or damp cloth
  • Do not eat or drink anything that may have been exposed
  • If taking potassium iodide (KI), follow official dosing instructions only
  • Prepare to shelter for at least 24 hours
3

First 24 Hours

  • Continue sheltering — radiation levels drop significantly after 24 hours
  • Use only sealed food and water supplies
  • Monitor official communications for evacuation orders
  • Avoid touching surfaces that may be contaminated
  • Designate a bathroom as a decontamination area if people must come in
  • Keep a log of symptoms for each person
4

Long-Term

  • Follow evacuation routes when officially cleared
  • Seek medical evaluation for radiation exposure symptoms
  • Do not return home until authorities confirm safety
  • Dispose of contaminated clothing and items as directed
  • Support family and community mental health recovery
  • Register with local emergency services for assistance
