The Roentgen Calculator was a popular civil defense accessory in the early sixties – no fallout shelter was complete without one. It was a tool that would theoretically allow the atomic bomb survivor to figure out just how screwed he or she was after an attack.

A variation of the Roentgen Calculator was used by Dr. Strangelove himself in Stanley Kubrick’s classic 1964 film. It was also used as a gimmick to help promote the film (see Press Book excerpt below).
