"Protect and Survive" was the title of a series of booklets and Information Film series produced by the British government during the late 1970s and early 1980s, dealing with emergency planning for a nuclear war.
The purpose of the programme was to provide the public with instructions on how to protect themselves and survive a nuclear attack. A copy of the 'Protect and Survive' booklet would have been distributed to every home in the UK, and the films would have been transmitted on domestic television.
Here is one of the film series, “Action After Warnings”.
