The Nevada Test Site, now known as the Nevada National Security Site, is an 1,350-square-mile research complex about 65 miles northwest of Las Vegas. The site features 1,100 buildings, 700 miles of roads, 10 heliports, and two airstrips. The original 680-square-mile site was established in 1950 by President Harry Truman and between 1951 and 1992, 928 announced nuclear tests occurred here. 828 of those tests occurred underground, leaving behind the numerous subsidence craters that can be seen.
After World War II, the United States government created the Atomic Energy Commission to oversee atomic science and technology. Fear of Soviet development of atomic weapons led to the rampant domestic testing of similar technologies. On January 27, 1951, testing at the NTS officially began with Operation Ranger. Atmospheric nuclear testing continued for nearly twelve years. Underground testing began with Operation Nougat in 1961.
During the 1950s and early 1960s, mushroom clouds from detonations could regularly seen as far as 100 miles from the site. The Las Vegas tourism industry capitalized on the testing, offering hotel rooms with views of detonations and publishing calendars of detonation times.
Nuclear fallout from the tests have affected civilians in Arizona, Nevada, Utah, Oregon, and Washington with the citizens of St. George, Utah being the most famously affected. From 1950 to 1980 the rates of cancer increased in affected areas and soldiers who witnessed tests at the NTS had has high as 50% greater rates of leukemia and other cancers. The Radiation Exposure Compensation Act of 1990 aimed to make payments to some of the people affected by fallout from these tests.
Many protests occurred at the site, most famously a 2,000-person demonstration in 1987 that led to the arrest of many prominent figures including astronomer Carl Sagan and actors Kris Kristofferson and Martin Sheen.
Full-scale nuclear weapons testing ended in the United States in 1992. The site is still used for radioactive waste management and for viability testing of the existing nuclear arsenal. Public tours are available.
