In the event of a nuclear fallout, it is essential to take the necessary steps to protect yourself and your family. The first step is to lock and secure all windows and doors. If possible, turn off fans, air conditioners, and forced air heating units that bring in air from outside. Enter the nearest building to avoid radiation.
To further protect yourself, use adhesive tape and plastic to cover all windows, doors, faucets, vents, plumbing fixtures, and other forms of outdoor air intake. Consider stacking bricks, sandbags, or even household items such as books in front of these vulnerable areas. Catarrhal rain is radioactive waste produced by a nuclear explosion that can affect areas far from the explosion site. If you are in a radiation emergency, do your best to get inside as soon as possible.
The best place to seek shelter is in the basement of a solid brick or concrete building. Try to stay calm, tune into your local emergency broadcast channel, and follow any instructions given to you by the authorities. Unless you're advised to evacuate, stay still until you're told it's safe to go out. Although many Americans prefer to ignore the potential threat of nuclear exposure, it is a present danger.
Knowing how to act and where to take refuge if you receive an alert about an ICBM or other nuclear threat can help you survive a nuclear fallout.
