Nuclear Weapons Testing
Nuclear weapons tests are experiments carried out to determine the performance of nuclear weapons and the effects of Nuclear explosion, their explosion. Nuclear testing is a sensitive political issue. Governments have often performed tests to signal strength. Because of their destruction and fallout, testing has seen opposition by civilians as well as governments, with international bans having been agreed on. Thousands of tests have been performed, with most in the second half of the 20th century. 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 tested at the Enewetak Atoll in the Marshall Islands on November 1, 1952 (local date), also by the United States. The largest nuclear weapon ever tested was the Tsar Bomba of the Soviet Union at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle Bravo Nuclear Test (cropped)
A castle is a type of fortification, fortified structure built during the Middle Ages predominantly by the nobility or royalty and by Military order (monastic society), military orders. Scholars usually consider a ''castle'' to be the private fortified house, fortified residence of a lord or noble. This is distinct from a mansion, palace, and villa, whose main purpose was exclusively for ''pleasance'' and are not primarily fortresses but may be fortified. Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts and 19th- and 20th-century homes built to resemble castles. Over the Middle Ages, when genuine castles were built, they took on a great many forms with many different features, although some, such as curtain wall (fortification), curtain walls, arrowslits, and portcullises, were commonplace. European-style castles originated in the 9th and 10th centuries after the fall of the Carolingian Empire, which resulted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
September 2016 North Korean Nuclear Test
The government of North Korea conducted a nuclear detonation on 9 September 2016, the fifth since 2006, at the Punggye-ri Nuclear Test Site, approximately northwest of Kilju City in Kilju County. Background North Korea's previous nuclear test was conducted 8 months earlier in January 2016 and drew sharp international condemnations. Despite calls from China and Russia to return to the six-party talks, North Korea maintained its nuclear and missile ambitions: * During the 7th Congress of the Workers' Party of Korea, Kim Jong Un announced a route of parallel development of nuclear weapons and the nation's economy, and the planned date for the fifth nuclear test launch was announced.Incredible photos of the military drill that's freaking out North Korea – D ...

January 2016 North Korean Nuclear Test
North Korea conducted its fourth nuclear detonation on 6 January 2016 at 10:00:01 UTC+08:30. At the Punggye-ri Nuclear Test Site, approximately northwest of Kilju City in Kilju County, an underground nuclear test was carried out. The United States Geological Survey reported a 5.1 magnitude earthquake from the location; the China Earthquake Networks Center reported the magnitude as 4.9. North Korean media announced that the country had successfully tested a hydrogen bomb in "self-defence against US". However, third-party experts as well as officials and agencies in South Korea questioned North Korea's claims and contend that the device was more likely to have been a fission bomb such as a boosted fission weapon. Such weapons use hydrogen fusion to produce smaller, lighter warheads suitable for arming a delivery device such as a missile, rather than to attain the destructive power of a true hydrogen bomb.

2013 North Korean Nuclear Test
On 12 February 2013, North Korean state media announced it had conducted an underground nuclear test, its third in seven years. A tremor that exhibited a nuclear bomb signature with an initial magnitude 4.9 (later revised to 5.1) was detected by the China Earthquake Networks Center, Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization and the United States Geological Survey. In response, Japan summoned an emergency United Nations meeting for 12 February and South Korea raised its military alert status. It is not known whether the explosion was nuclear, or a conventional explosion designed to mimic a nuclear blast; as of two days after the blast, Chinese, Japanese, and South Korean investigators had failed to detect any radiation. Test On 12 February 2013, a spokesman for North Korea's army command said it had successfully conducted a third underground nuclear weapons test, according to the Yonhap.

2006 North Korean Nuclear Test
On October 9, 2006, North Korea performed its first nuclear test, detonating a plutonium-based device underground. On October 3, 2006, North Korea announced its intention to conduct a nuclear test. The blast is generally estimated to have had an explosive force of less than one kiloton, and some radioactive output was detected. United States officials suggested the device may have been a nuclear explosive that misfired. An anonymous official at the North Korean Embassy in Beijing told a South Korean newspaper that the explosive output was smaller than expected. Because of the secretive nature of North Korea and small yield of the test, there remains some question as to whether it was a successful test of an unusually small device (which would have required sophisticated technology), or a partially failed " fizzle" or dud. A scientific paper later estimated the yield as 0.48 kilotons.Lian-Feng Zhao, Xiao-Bi Xie, Wei-Min Wang, and Zhen-Xing Yao,Regional Seismic Characteristics o ...

India And Weapons Of Mass Destruction
India possesses nuclear weapons and previously developed chemical weapons. Although India has not released any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 180 nuclear weapons. India has conducted nuclear weapons tests in a pair of series namely '' Pokhran I'' and '' Pokhran II''. India is a member of three multilateral export control regimes — the Missile Technology Control Regime, Wassenaar Arrangement and Australia Group. It has signed and ratified the Biological Weapons Convention and the Chemical Weapons Convention. India is also a subscribing state to the Hague Code of Conduct.

Comprehensive Nuclear-Test-Ban Treaty
The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a multilateral treaty to ban nuclear weapons test explosions and any other nuclear explosions, for both civilian and military purposes, in all environments. It was adopted by the United Nations General Assembly on 10 September 1996, but has not entered into force, as nine specific nations have not ratified the treaty. History Background The movement for international control of nuclear weapons began in 1945, with a call from Canada and the United Kingdom for a conference on the subject. In June 1946, Bernard Baruch, an emissary of President Harry S. Truman, proposed the Baruch Plan before the United Nations Atomic Energy Commission, which called for an international system of controls on the production of atomic energy. The plan, which would serve as the basis for U.S. nuclear policy into the 1950s, was rejected by the Soviet Union as a US ploy to cement its nuclear dominance.
