If A Nuclear Bomb Is Dropped On Your City, Here's Where You Should Run And Hide

But if the nice, thick-walled building would take about 15 minutes travel time, it's better to hole up in the flimsy shelter for awhile — but you should probably leave for a better shelter after roughly an hour (and maybe pick up some beers and sodas on the way: A study in the '50s found they taste fine after a blast).

This is because some of the most intense fallout radiation has subsided by then, though you still want to reduce your exposure.

One of the big advantages of the approach that this paper uses is that, to decide on a strategy, evacuation officials need to consider only the radiation levels near shelters and along evacuation routes — the overall pattern of the radioactive death-cloud does not factor into the models. This means decisions can be made quickly and without much communication or central organization (which may be spare in the minutes and hours after a blast).

Other researchers have analyzed other similar scenarios in papers, whose findings are summarized in the chart below:
