Formerly known as the '''Nevada Proving Grounds''' of the [[United States Army]], the site was acquired in 1951 to be the testing venue for the American [[Nuclear weapon|nuclear devices]]. The first [[Operation Ranger|atmospheric test]] was conducted at the site's [[Frenchman Flat]] area by the [[United States Atomic Energy Commission]] (USAEC) on January 27, 1951. About 928 [[Nuclear weapons testing|nuclear tests]] were conducted here through 1994, when the United States stopped its underground nuclear testing.

Homes and commercial buildings of many different types and styles were built to standards typical of American and (less-often) European cities. Other such structures included military fortifications (of types used by both [[NATO]] and the Soviet-led [[Warsaw Pact]]) and civil-defense as well as "backyard"-type shelters. In such a typical test, several of the same buildings and structures might be built using the same layouts and plans with different types of materials, paints, general landscaping, cleanliness of the surrounding yards, wall-angles or varying distances from ground zero. Mannequins were placed in and around the test vehicles and buildings, aside from some left out in the open, for testing clothing and shock effects. High-speed cameras were placed in protected locations to capture effects of radiation and shock waves. Typical imagery from these cameras shows paint boiling off the buildings, which are then pushed violently away from ground zero by the shock wave before being drawn toward the detonation by the suction caused by the climbing mushroom cloud. Footage from these cameras has become iconic, used in various media and available in the public domain.<ref>{{citation| title=Operation Cue (1964 revision)| publisher=U.S. Department of Defense, Office of Civil Defense| year=1964| url=https://archive.org/details/Operatio1964| access-date=May 7, 2018}}</ref> This testing allowed the development of Civil Defense guidelines, distributed to the public, to increase the likelihood of survival in case of air- or spaceborne nuclear attack. ==Environmental impact== Each of the below-ground explosionsβsome as deep as 5,000 feet (1.5 km)βvaporized a large chamber, leaving a cavity filled with [[Radioactive decay|radioactive]] rubble.

Although radioactivity levels in the water continue to decline over time, the longer-lived isotopes like plutonium or uranium could pose risks for thousands of years.<ref name="vart" /> The Department of Energy has more than 48 monitoring wells at the site.
