On the Beach

On the Beach is a book by Nevil Shute that explores the aftermath of a nuclear war on the northern hemisphere. The protagonists live in Southern Australia, but deadly radiation is heading that direction, though it isn't yet there. The path of the radiation can be tracked by radio stations going silent.

Much of the book is about southern Australians trying to live normally while waiting for the end, but there is another plot. There is a Morse-like radio signal coming all the way from Seattle, and a submarine goes on a mission to see if there are survivors there or if the radiation up there has died down any.

The book was adapted into two movies by the same name, first in 1959 and then in 2000. The first movie has inspired the Strugatsky Brothers to write Far Rainbow in 1962.
