Notice the fallout shelter sign on the left side of this photograph? Such designated areas were common civil defense measures during the Cold War era. The term "fallout" referred to the radioactive dust that formed in the aftermath of a nuclear fireball; an underground shelter would provide some protection against these particles until the radiation had decayed to a safer level. - Stephen Fagin, Curator
