text: Fallout Protection: What To Know And Do About Nuclear Attack was an official United States federal government booklet released in December 1961 by the United States Department of Defense and the Office of Civil Defense.
  The first page of the book is a note from then-U.S. Secretary of Defense Robert McNamara explaining that the booklet is a 48 page book made for the result of the first task he was given when he assumed responsibility for the Federal Civil Defense Program in August 1961. The task, assigned by President John F. Kennedy, was to "give the American people the facts they need to know about the dangers of a thermonuclear attack and what they can do to protect themselves."
