For nuclear weapon tests, a salvo is defined as two or more underground nuclear explosions conducted at a test site within an area delineated by a circle having a diameter of two kilometers and conducted within a total period of time of 0.1 second.
Nuclear weapons testing did not produce scenarios like nuclear winter as a result of a scenario of a concentrated number of nuclear explosions in a nuclear holocaust, but the thousands of tests, hundreds being atmospheric, did nevertheless produce a global fallout that peaked in 1963 (the bomb pulse), reaching levels of about 0.15 mSv per year ...
The nuclear weapons tests of the United States were performed from 1945 to 1992 as part of the nuclear arms race. The United States conducted around 1,054 nuclear tests by official count, including 216 atmospheric, underwater, and space tests.
The resumption of testing by the world's two biggest nuclear powers would usher in a new and precarious era nearly 80 years since the United States tested the first nuclear bomb at Alamogordo, New ...
It tested its first hydrogen bomb ("Test No. 6") in 1967, 32 months after testing its first nuclear weapon (the shortest fission-to-fusion development known in history). [62] China is the only NPT nuclear-weapon state to give an unqualified negative security assurance with its "no first use" policy.
During the 1958 moratorium on nuclear testing, a number of sub-critical tests were performed underground to learn more about the dynamics of explosions and the metallurgy of plutonium. The US's first nuclear weapons lab, founded in the Manhattan Project in high secrecy. Tech Area 49 is an open area south of the lab, where zero-yield tests were ...
Trinity test on 16 July 1945, was the world's first test of a nuclear weapon (yield of around 20 kt). Operation Crossroads series in July 1946, was the first postwar test series and one of the largest military operations in U.S. history.
Articles relating to nuclear weapons testing, experiments carried out to determine the effectiveness, yield, and explosive capability of nuclear weapons.Testing nuclear weapons offers practical information about how the weapons function, as well as how detonations are affected by different conditions; and how personnel, structures, and equipment are affected when subjected to nuclear explosions.
