Matt Novak hits some highlights from Joanne Brown's 1988 Journal of American History paper A is for Atom, B is for Bomb (paywalled link), which discusses the weird, grim stuff that America contemplated at the height of the cold war, and worried about how it would identify the charred corpses of children after a nuclear blast:
In February of 1952 the city of New York bought 2.5 million dog tags. By April of that year, just about every kid in the city from kindergarten to fourth grade had a tag with their name on it. Kids in many other cities like San Francisco, Seattle, Las Veagas and Philadelphia also got dog tags, allowing for easy identification should the unthinkable occur.
But educators weren't considering just dog tags to identify the scores of dead and injured children that would result if the cold war suddenly turned hot. They also considered tattoos.
