Daily life in the area of nuclear testing in Nevada. Instructions for residents
War in Asia caused the United States to reconsider testing nuclear weapons in the Pacific Ocean and to look for a continental test site. Conflict in Korea justified a less-expensive continental testing site in order to maintain U.S. nuclear weapons superiority. A Nevada site north of Las Vegas was chosen because of its safety features, which included low population density, favorable meteorological conditions (a prevailing easterly wind blowing away from the populous west coast), and good geographical features.
