Although this may not be the most likely disaster you will deal with, it never hurts to be prepared. Knowing what to do and where to go after a nuclear bomb has exploded will give you the best chance of surviving the radiation .
Step 1: Get potassium iodide
Have potassium iodide on hand; you may need it to protect your thyroid from the radioactive iodine fallout of a nuclear event.
Step 2: Go below
If an attack is imminent, get indoors and go as far below ground as you can. If that's not possible, seek whatever shelter you can.
Step 3: Seal yourself in
Once indoors, close all windows and doors and turn off air conditioners, heaters, and and other ventilation systems.
Step 4: Seal up your car
If you can't get to a building, stay inside your car. Close the windows and vents, turn off the heat and A/C, and hold a cloth over your mouth and nose to avoid breathing in radioactive dust and smoke.
Step 5: Protect yourself outdoors
If you're caught outdoors or very near the blast when it happens, don't look at it or you risk temporary or even permanent blindness.
Step 6: Stay put
If you are more than 10 miles from the epicenter of the blast, remain in the shelter for 48 to 72 hours after the blast.
Step 7: Get out of Dodge!
If you are closer than 10 miles to the epicenter after the explosion, get moving! You have 10 to 20 minutes to get at least a mile away from the mushroom cloud, or you risk lethal radiation poisoning.
Step 8: Cover up
Keep your mouth, nose, and as much of your skin covered as you move away from the blast area.Once you're at a safe distance, take off your clothes; this alone may get rid of up to 80 percent of radioactive dust. Then take a shower, which will further reduce your exposure.
Step 9: Get decontaminated
Rid your body of radioactive material as soon as possible by reporting to the nearest decontamination center set up in your area.
