Nuclear weapons tests are experiments carried out to determine the performance, yield, and effects of nuclear weapons. Such tests have resulted until 2020 in up to 2.4 million people dying from its global fallout. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different ...
France became a nuclear power in 1960, and French nuclear stockpiles peaked at just over 500 nuclear weapons in 1992. [1] China developed its first nuclear weapon in 1964; its nuclear stockpile increased until the early 1980s, when it stabilized at between 200 and 260. [1] India became a nuclear power in 1974, while Pakistan developed its first ...
Underground nuclear testing is the test detonation of nuclear weapons that is performed underground. When the device being tested is buried at sufficient depth, the nuclear explosion may be contained, with no release of radioactive materials to the atmosphere. The extreme heat and pressure of an underground nuclear explosion causes changes in ...
