HOW TO PREPARE
PHYSICALLY:
Make a Plan
If a nuclear attack does happen, you must plan to stay sheltered for at least 48 hours, maybe longer. Having enough food and medical supplies can put your mind at ease.
Get Communications Supplies
Have a radio, either crank or solar powered. Get a simple whistle which could be a signal for help. Your cell phone could be good, but be prepared if service goes down.
Seek Shelter Immediately
In the event of a nuclear detonation you could only have about 10-30 seconds to seek shelter. If you can't find shelter, find a depressed area and lay face down exposing as little skin as possible.
Ration Your Supplies
Processed foods are okay to eat, as long as the container has no punctures. Plants in a "hot zone" are edible and plants with edible roots (carrots and potatoes) are highly recommended. Water from an underground source is your best option.
Cover as Much Skin as Possible
When outside wear hats, gloves, goggles, closed sleeve shirts, etc. to prevent Beta burns. Decontaminate by shaking your clothes constantly and washing with water, any exposed skin to reduce risk of burns.
