Test Ban Treaty (other)
Three test ban treaties aimed at prohibiting most nuclear weapons testing have been adopted: * The Partial Test Ban Treaty, adopted in 1963, signed by the Soviet Union, the United Kingdom, the United States, prohibited all testing except underground tests * Threshold Test Ban Treaty, adopted in 1974 between the United States and Soviet Union limiting the yield of nuclear tests to 150 kilotons * Comprehensive Nuclear-Test-Ban Treaty, adopted by the United Nations General Assembly in 1996 but not in force, by which states agree to ban all nuclear explosions in all environments {{Disambiguation ...

Nuclear Weapons Testing
Nuclear weapons tests are experiments carried out to determine nuclear weapons' effectiveness, Nuclear weapon yield, yield, and explosive capability. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different conditions, and how personnel, structures, and equipment are affected when subjected to Nuclear explosion, nuclear explosions. However, nuclear testing has often been used as an indicator of scientific and military strength. Many tests have been overtly political in their intention; most List of countries with nuclear weapons, nuclear weapons states publicly declared their nuclear status through a nuclear test. The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield approximately TNT equivalent, equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of an engineered device, codenamed "Ivy Mike", was teste ...

Partial Test Ban Treaty
The Partial Test Ban Treaty (PTBT) is the abbreviated name of the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, which prohibited all nuclear weapons testing, test detonations of nuclear weapons except for those conducted underground nuclear weapons testing, underground. It is also abbreviated as the Limited Test Ban Treaty (LTBT) and Nuclear Test Ban Treaty (NTBT), though the latter may also refer to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which succeeded the PTBT for ratifying parties. Negotiations initially focused on a comprehensive ban, but that was abandoned because of technical questions surrounding the detection of underground tests and Soviet concerns over the intrusiveness of proposed verification methods. The impetus for the test ban was provided by rising public anxiety over the magnitude of nuclear tests, particularly tests of new thermonuclear weapons (hydrogen bombs), and the resulting nuclear fallout. A test ...

Threshold Test Ban Treaty
The Treaty on the Limitation of Underground Nuclear Weapon Tests, also known as the Threshold Test Ban Treaty (TTBT), was signed in July 1974 by the United States and Soviet Union. It establishes a nuclear "threshold" by prohibiting nuclear tests of devices having a yield exceeding 150 kilotons after March 31, 1976. The threshold is militarily important since it removes the possibility of testing new or existing nuclear weapons going beyond the fractional-megaton range. In the 1960s, many tests above 150 kilotons were conducted by both countries. The mutual restraint imposed by the Treaty reduced the explosive force of new nuclear warheads and bombs which could otherwise be tested for weapons systems. Of particular significance was the relationship between explosive power of reliable, tested warheads and first-strike capability. Agreement on the Threshold Test Ban Treaty was reached during the summit meeting in Moscow in July 1974. Ratification did not occur until 1990 for a numb ...
