6. Find a “Post-Blast” Shelter If Possible
Here’s where your options begin to expand significantly. While the US government recommends that you simply shelter in place, recent studies have shown better survival rates IF you can relocate to a better shelter within 5 minutes.
If you can get inside a fallout shelter, even after the blast wave has passed, do so. Radioactive fallout travels a bit slower, thus there may still be time to avoid radiation poisoning.
Depending how close you are to ground zero, you may have significantly more time to find a solid shelter option. The basement of an in-tact house is good option if a shelter isn’t nearby.
Wind direction will determine where the cloud of radioactive particles will be carried and this will trigger warnings hundreds of miles away. Be prepared to take shelter in the event you are downwind.
Be prepared to stay in your shelter for at least 24 hours.
