In the event of a nuclear attack, it is essential to take immediate action to protect yourself and those around you. The best way to do this is to enter the nearest building and move away from any windows. This will help provide protection from the explosion, heat, and radiation that can be caused by a nuclear detonation. It is also important to cover yourself with anything that can offer protection, such as furniture or clothing.
Lie on your stomach to protect exposed skin from flying heat and debris. If there are no sturdy buildings nearby, it is still better to be indoors than outside. Entering the nearest building will help protect you from radiation. The best shelters are buildings such as schools or offices with few or no windows and a basement for camping. It is also important to be aware of the different types of nuclear emergencies that can occur. An improvised nuclear device (IND) is a weapon purchased, stolen, or otherwise obtained from a nuclear state, or a weapon manufactured by a terrorist group from illegally obtained nuclear weapons material.
