Experts say the shelters in schools and courthouses are often aging relics from the Cold War that haven't been maintained. In a real nuclear strike, taking cover in a building bearing the rusted yellow fallout-shelter symbol may not be the best option anymore. 16, 2018 photo, pedestrians pass a fallout shelter sign hanging outside the Cooper Station post office in New York. In New York City alone, there were believed to be about 18,000.

The fallout shelters, marked with metal signs featuring the symbol for radiation, were set up in thousands of buildings nationwide in the early 1960s amid the nuclear arms race.

A fallout shelter sign hangs on a building on East 9th Street in New York City on Tuesday.
