Is the US better prepared for a nuclear blast today than it was 60 years ago?

Despite advances in technology and decades of research, experts worry we are still underprepared to handle a blast - and the aftermath

If you look hard enough, you'll spot faded yellow signs proclaiming Fallout shelter" around New York City. They are remnants of a cold war program that signaled spaces within ordinary buildings - from schools to banks to the Brooklyn Bridge - with adequate supplies and walls thick enough for riding out a nuclear blast safely.

Many of these windowless shelters housed little more than rats and sewage before the practice was terminated in 1979. In 2017, the city's department of education ordered the misleading" signs removed from its buildings, but many others remain - vestiges of nuclear fears that never materialized.
