Pack an emergency kit with non-perishable food, clean water, medications, extra flashlights and batteries, hand crank radios, blankets, and other essential items.
Look for the safest place in your home, like the basement or ground floor, and stay there until the alarm is raised to go outside.
Cover yourself with long-sleeved clothes, long pants and a hat to protect your skin and hair from radioactive particles. Also use a face mask or wet washcloth to protect your airways.
Close all windows and doors, covering the cracks with rags or duct tape. This will prevent radioactive particles from entering your home.
Monitor the News: Listen to the crank radio for local authority news and instructions. Follow the directions and instructions given.
Stay in your home until given the all-clear by local authorities. Avoid going out unless absolutely necessary.
If your tap water isn't safe to drink, purify it with filters or other purification techniques.
By following these guidelines, you will have a better chance of surviving nuclear fallout in your home. Remember that preparation is key to dealing with emergency situations like this.
