Don’t Panic, Just Prep: Your Guide To Surviving A Nuclear Emergency - Page 2

Get underground—and fast!

According to Business Insider, it depends on the launch location. For example, if Russia launched a missile from international waters just off the U.S. East Coast, residents in cities like New York, Boston, and Washington, D.C., might only have 10 to 15 minutes to prepare. In such an event, most people would receive a Wireless Emergency Alert (WEA) on their phones, warning of incoming missiles and urging them to seek shelter immediately. The Emergency Alert System (EAS) would broadcast the same message on television, radio, satellite, and cable networks. Additionally, the president could issue a “presidential alert” to all cell phones nationwide.

If an attack warning is issued, immediate shelter is critical. The safest place to be is underground, or, if that’s not possible, inside a sturdy brick or concrete building, according to the Red Cross. Head to the lowest level or the center of the structure to put as much material between you and the radioactive fallout as possible. Turn off ventilation systems like fans, air conditioners, and forced-air heating units that could draw in contaminated air. Close all windows, doors, and fireplace dampers to seal the space. 

Radiation is most dangerous in the first few hours after a blast, but it decreases rapidly. Plan to stay sheltered for at least 24 hours unless instructed otherwise by authorities, though in some cases, you may need to remain inside for up to a month.
