Surviving a Nuclear Blast
A nuclear blast is an explosion with intense light and heat. Next, there is a damaging pressure wave and widespread dispersion of radioactive material. This material can contaminate the air, water, and ground surfaces for miles.
If There Is a Nuclear Blast
- Quickly assess the situation.
- Get out of the area or get into a nearby building to limit your
radiation exposure.
- Shelter as far below ground as possible:
- Close windows and doors.
- Turn off all heating, cooling and ventilation systems.
- Stay put and stay informed through TV, radio, or the Internet.
- Shield yourself with a thick piece of material between you and any
radioactive materials.
- Stay away from the radiation source or blast to lower your exposure.
- Cut the time you are exposed to radiation to reduce your risk.
- Consider taking Potassium Iodide tablets to protect your thyroid gland from radiation damage.
