Limited Nuclear Test Ban Treaty
The Partial Test Ban Treaty (PTBT), formally known as the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, prohibited all test detonations of nuclear weapons except for those conducted 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 ban was also seen as a means of slowing nuclear proliferation and the nucle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arms Control
Arms control is a term for international restrictions upon the development, production, stockpiling, proliferation and usage of small arms, conventional weapons, and weapons of mass destruction. Historically, arms control may apply to melee weapons (such as swords) before the invention of firearm. Arms control is typically exercised through the use of diplomacy which seeks to impose such limitations upon consenting participants through international treaties and agreements, although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country. Enactment Arms control treaties and agreements are often seen as a way to avoid costly arms races which could prove counter-productive to national aims and future peace. Some are used as ways to stop the spread of certain military technologies (such as nuclear weaponry or missile technology) in return for assurances to potential developers that they will not be victims of those tech ...

Rongelap Atoll
Rongelap Atoll ( ; , ) is an uninhabited coral atoll of 61 islands (or motus) in the Pacific Ocean, and forms a legislative district of the Ralik Chain of the Marshall Islands. Its total land area is . It encloses a lagoon with an area of . It is historically notable for its close proximity to US hydrogen bomb tests in 1954, and was particularly devastated by fallout from the Castle Bravo test. The population asked the US (several times) to move them from Rongelap following the test due to high radiation levels, but with no success; so they asked global environmental group Greenpeace to help. The Rainbow Warrior made three trips moving the islanders, their possessions and over 100 tons of building materials to the island of Mejato in the Kwajalein Atoll, 180 kilometers away. History The Marshall Islands, of which Rongelap Atoll is a part, were first settled by Micronesians. The first sighting recorded by Europeans was by Spanish navigator Álvaro de Saavedra on 1 Ja ...

Megatons Of TNT
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. A ton of TNT equivalent is a unit of energy defined by convention to be (). It is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of trinitrotoluene (TNT). In other words, for each gram of TNT exploded, (or 4184 joules) of energy are released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. A related concept is the physical quantity TNT-equivalent mass (or mass of TNT equivalent), expressed in the ordinary units of mass and its multiples: kilogram (kg), megagram (Mg) or tonne (t), etc. Kiloton and megaton The "kiloton (of TNT equivalent)" is a unit of energy equal to 4.184 terajoules (). A kiloton of TNT can be visualized as a cube of TNT on a si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Castle
Operation Castle was a United States series of high-yield (high-energy) nuclear tests by Joint Task Force 7 (JTF-7) at Bikini Atoll beginning in March 1954. It followed ''Operation Upshot–Knothole'' and preceded '' Operation Teapot''. Conducted as a joint venture between the Atomic Energy Commission (AEC) and the Department of Defense (DoD), the ultimate objective of the operation was to test designs for an aircraft-deliverable thermonuclear weapon. All the devices tested, which ranged in weight from , were built to be dropped from aircraft. However, ballistic casings, fins and fusing systems would have to be attached. Operation Castle was considered by government officials to be a success as it proved the feasibility of deployable "dry" fuel designs for thermonuclear weapons. There were technical difficulties with some of the tests: one device had a yield much lower than predicted (a " fizzle"), while two other bombs detonated with over twice their predicted yields.

Bikini Atoll
Bikini Atoll ( or ; Marshallese language, Marshallese: , , ), known as Eschscholtz Atoll between the 19th century and 1946, is a coral reef in the Marshall Islands consisting of 23 islands surrounding a central lagoon. The atoll is at the northern end of the Ralik Chain, approximately northwest of the capital Majuro. After the Second World War, the atoll was chosen by the United States as a nuclear weapon testing site. It would be the site of the fourth nuclear bomb detonation and would go on to be the site of many more tests. The people that lived on Bikini—all 167 of the atoll's inhabitants—agreed to relocate after being informed of the plan to test then-new nuclear weapons, of great importance to humankind, though it is sometimes considered a forced relocation. In 1946 they moved to Rongerik, a small island east of Bikini Atoll, but it turned out to have inadequate resources to support the population. The islanders began experiencing starvation by early 1948, and they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle Bravo
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of ''Operation Castle''. Detonated on 1 March 1954, the device remains the most powerful nuclear weapon, nuclear device ever detonated by the United States and the first lithium deuteride-fueled thermonuclear weapon tested using the Teller–Ulam design. Castle Bravo's Nuclear weapon yield, yield was , 2.5 times the predicted , due to unforeseen additional reactions involving Isotopes of lithium, lithium-7, which led to radioactive contamination in the surrounding area. Radioactive nuclear fallout, the heaviest of which was in the form of pulverized surface coral from the detonation, fell on residents of Rongelap Atoll, Rongelap and Utirik Atoll, Utirik atolls, while the more particulate and gaseous fallout spread around the world. The inhabitants of the islands were evacuated three days later and suffered radiation sickn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Globe And Mail
''The Globe and Mail'' is a Newspapers in Canada, Canadian newspaper printed in five cities in Western Canada, western and central Canada. With a weekly readership of more than 6 million in 2024, it is Canada's most widely read newspaper on weekdays and Saturdays, although it falls slightly behind the ''Toronto Star'' in overall weekly circulation because the ''Star'' publishes a Sunday edition, whereas the ''Globe'' does not. ''The Globe and Mail'' is regarded by some as Canada's "newspaper of record". ''The Globe and Mail''s predecessors, ''The Globe (Toronto newspaper), The Globe'' and ''The Daily Mail and Empire'' were both established in the 19th century. The former was established in 1844, while the latter was established in 1895 through a merger of ''The Toronto Mail'' and ''The Empire (Toronto), The Empire''. In 1936, ''The Globe'' and ''The Mail and Empire'' merged to form ''The Globe and Mail''. The newspaper was acquired by FP Publications in 1965, who later sold the p ...

Trinity Test
Trinity was the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, or "gadget", of the same design as the Fat Man bomb later detonated over Nagasaki, Japan, on August 9, 1945. Concerns about whether the complex Fat Man design would work led to a decision to conduct the first nuclear test. The code name "Trinity" was assigned by J. Robert Oppenheimer, the director of the Los Alamos Laboratory, possibly inspired by the poetry of John Donne. The test, both planned and directed by Kenneth Bainbridge, was conducted in the Jornada del Muerto desert about southeast of Socorro, New Mexico, on what was the Alamogordo Bombing and Gunnery Range (renamed the White Sands Proving Ground just before the test). The only structures originally in the immediate vicinity were the McDonald Ranch House and its ancillary buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Bombs
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear bombs have had yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as can release energy equal to more than 1.2 megatons of TNT (5.0 PJ). Apart from the blast, effects of nuclear weapons include firestorms, extreme heat and ionizing radiation, radioactive nuclear fallout, an electromagnetic pulse, and a radar blackout. The first nuclear weapons were developed by the Allied Manhattan Project during World War II. Their production continues to require a large scientific and industrial complex, primarily ...
