Cobalt Bomb
A cobalt bomb is a type of " salted bomb": a nuclear weapon designed to produce enhanced amounts of radioactive fallout, intended to contaminate a large area with radioactive material, potentially for the purpose of radiological warfare, mutual assured destruction or as doomsday devices. There is no firm evidence that such a device has ever been built or tested. History The concept of a cobalt bomb was originally described in a radio program by physicist Leó Szilárd on February 26, 1950. His intent was not to propose that such a weapon be built, but to show that nuclear weapon technology would soon reach the point where a doomsday device could end human life on Earth. The Operation Antler/Round 1 test by the British at the Tadje site in the Maralinga range in Australia on September 14, 1957, tested a bomb using cobalt pellets as a radiochemical tracer for estimating nuclear weapon yield. This was considered a failure, and the experiment was not repeated. In Russia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt-60
Cobalt-60 (Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope . (PDF also located aCanadian Nuclear FAQ Measurable quantities are also produced as a by-product of typical nuclear power plant operation and may be detected externally when leaks occur. In the latter case (in the absence of added cobalt) the incidentally produced is largely the result of multiple stages of neutron activation of iron isotopes in the reactor's steel structures via the creation of its precursor. The simplest case of the latter would result from the activation of . undergoes beta decay to an excited state of the stable isotope nickel-60 (), which then emits two gamma rays with energies of and . The overall equation of the nuclear reaction (activation and decay) is: + n → → + e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Fission
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission was discovered by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Hahn and Strassmann proved that a fission reaction had taken place on 19 December 1938, and Meitner and her nephew Frisch explained it theoretically in January 1939. Frisch named the process "fission" by analogy with biological fission of living cells. In their second publication on nuclear fission in February 1939, Hahn and Strassmann predicted the existence and liberation of additional neutrons during the fission process, opening up the possibility of a nuclear chain reaction. For heavy nuclides, it is an exothermic reaction which can release large amounts of energy both as electromagnetic radiat ...

Thermonuclear Weapon
A thermonuclear weapon, fusion weapon or hydrogen bomb (H-bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make possible the use of non-fissile depleted uranium as the weapon's main fuel, thus allowing more efficient use of scarce fissile material. Its multi-stage design is distinct from the usage of fusion in simpler Boosted fission weapon, boosted fission weapons. The first full-scale thermonuclear test (Ivy Mike) was carried out by the United States in 1952, and the concept has since been employed by at least the five recognized List of states with nuclear weapons#Recognized nuclear-weapon states, nuclear-weapon states and United Nations Security Council, UNSC Permanent members of the United Nations Security Council, permanent members: the Nuclear weapons ...

Dmitry Kiselyov
Dmitry Konstantinovich Kiselyov (; born April 26, 1954) is a Russian TV presenter and propagandist. In 2013, Kiselyov was appointed by Russian President Vladimir Putin to head '' Rossiya Segodnya'', a Russian state-controlled media group. He also serves as deputy director of the All-Russia State Television and Radio Broadcasting Company. His comments have been controversial both in Russia and in the West, especially regarding homosexuality and the Euromaidan, the Annexation of Crimea by the Russian Federation in 2014 and his allegation of the US standing on "the side of the terrorist caliphate" ISIS, destroying Syria and bringing down Metrojet Flight 9268. Kiselyov has been on the list of personal sanctions imposed by the EU since 2014. In January 2023, Ukraine imposed economic sanctions on Dmitry for his support of 2022 Russian invasion of Ukraine. Early life Kiselyov was born in Moscow on April 26, 1954. He was brought up in a musical environment, being the nephew of Sovie ...

Nuclear Posture Review
The Nuclear Posture Review (NPR) is a process “to determine what the role of nuclear weapons in U.S. security strategy should be.” NPRs are the primary document for determining U.S. strategy for nuclear weapons and it outlines an overview of U.S. nuclear capabilities, changes to current stockpiles and capabilities, plans for deterrence, and plans for arms control policy with other nations. History 1994 NPR The first NPR was ordered by Department of Defense (DoD) Secretary Les Aspin, to create a document that comprehensively provides an overview of the United States' nuclear deterrent capabilities in 1993. The document was inspired by the Bottom-Up Review that was also performed by the DoD. The general theme for the first NPR was to lead and hedge threats from abroad. The review was organized around six areas of focus: Role of nuclear weapons, nuclear force structure, nuclear force options, nuclear safety and security, and relationship between US nuclear posture, counter-pro ...
