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.
Afterwards, the Comprehensive Test Ban Treaty was signed and ratified by the major nuclear weapons powers, and the number of worldwide nuclear tests decreased rapidly. [24] India and Pakistan conducted nuclear tests in 1998, but afterwards only North Korea conducted nuclear tests--in 2006, 2009, 2013, twice in 2016, and in 2017. [24] [25]
