The ARAC project is a Department of Energy (DOE) sponsored real-time emergency response service available for use by both federal and state agencies in case of a potential or actual atmospheric release of nuclear material aka a nuclear detonation. At the time this film was produced, ARAC was using a hemispherical computer model developed in part by Leonard A. Lawson to predict the evolution of the nuclear cloud. The study shown in the film lasted for 11 days, and provided an estimate of the dose patterns over Europe and the Northern Hemisphere. Results of ARAC’s wor
