The Nevada Test Site, renamed the Nevada National Security Site in 2010, is a U.S. Department of Energy reservation in Nye County, Nevada, about 105 km (65 miles) northwest of Las Vegas, where the United States carried out most of its nuclear weapons tests from 1951 to 1992. [1]
Establishment

President Harry Truman authorised the site on 18 December 1950, setting aside about 1,760 km² (680 square miles) of the Nellis Air Force gunnery and bombing range. It was called the Nevada Proving Ground until 1955. The site now covers about 3,500 km² (1,350 square miles).[1]
Nuclear tests

The first test, part of Operation Ranger, was a bomb dropped on Frenchman Flat on 27 January 1951. About 100 atmospheric tests followed, the last on 17 July 1962. In all, 928 announced nuclear tests were carried out at the site, 828 of them underground, most at Yucca Flat. The last, code-named Divider, took place on 23 September 1992. Since then the United States has observed a halt to nuclear testing, although it has carried out more than 27 "subcritical" experiments at the site.[1]
Fallout and protests

Fallout from the atmospheric tests drifted over communities downwind, especially in Utah, and has been linked to increased cancer rates; the Radiation Exposure Compensation Act of 1990 offered payments to affected "downwinders". The site was also a focus of anti-nuclear protest: government records list 536 demonstrations between 1986 and 1994, with more than 15,000 arrests.[1]
Operations

Defence contractors including EG&G helped run the site during the testing era. It is now managed for the National Nuclear Security Administration by a private consortium.[1][2]
