• On January 27, 1951, the United States government detonated the first of its series of atomic bombs at the Nevada Test Site. The isolated Nevada Test Site, now the Nevada National Security Site, was the primary location used for testing nuclear devices in the United States.

    The U.S. nuclear research and development program altered the geography of the West. On the one hand, federal funding allowed new research stations to be built, infrastructure to be expanded, and resulted in economic benefits for the state of Nevada. On the other hand, the explosions caused habitat destruction in the unique desert area. Craters still pockmark the landscape. The detonations also created radioactive fallout. When a nuclear device is detonated, it creates radioactive atoms. These radioactive atoms can cause cancer and other health problems. The lasting effect of the levels of radioactivity on the people and organisms in the Nevada Test Site area has been debated. However, it was significant enough as to cause the government to stop testing at the site.
