Reggane Series, French Nuclear Tests
The Reggane series was a group of 4 atmospheric A-bomb nuclear tests conducted by France between February 1960 and April 1961, close to the end of the Algerian War. The bombs were detonated at the Saharan Military Experiments Centre near Reggane, French Algeria in the Sahara desert region of Tanezrouft, by the Nuclear Experiments Operational Group (GOEN), a unit of the Joint Special Weapons Command. The series saw the explosion of the first French nuclear weapon and was followed by the In Ekker series. Codenames All four operations were named after the jerboa (''Gerboise''), a desert rodent found in the Sahara, with the adjunction of a colour. The first three colours adjuncted (blue, white and red) are said to come from the French Flag.

Elevation
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). The term ''elevation'' is mainly used when referring to points on the Earth's surface, while ''altitude'' or ''geopotential height'' is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and '' depth'' is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge, the summits of Mount Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance. Aviation In aviation the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Nuclear Weapons
Nuclear weapons possess enormous destructive power from nuclear fission or combined fission and fusion reactions. Building on scientific breakthroughs made during the 1930s, the United States, the United Kingdom, Canada, and free France collaborated during World War II, in what was called the Manhattan Project, to build a fission weapon, also known as an atomic bomb. In August 1945, the atomic bombings of Hiroshima and Nagasaki were conducted by the United States against Japan at the close of that war, standing to date as the only use of nuclear weapons in hostilities. The Soviet Union started development shortly after with their own atomic bomb project, and not long after, both countries were developing even more powerful fusion weapons known as hydrogen bombs. Britain and France built their own systems in the 1950s, and the list of states with nuclear weapons has gradually grown larger in the decades since. Physics and politics in the 1930s and 1940s In the first decades of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Algiers Putsch
The Algiers putsch (french: Putsch d'Alger or ), also known as the Generals' putsch (''Putsch des généraux''), was a failed coup d'état intended to force President of France, French President Charles de Gaulle not to abandon French Algeria, along with the resident European community and pro-French Muslims. Organised in French Algeria by retired French Army generals Maurice Challe (former commander-in-chief in French Algeria), Edmond Jouhaud (former Inspector general, Inspector General of the French Air Force), André Zeller (former Chief of Staff of the French Army) and Raoul Salan (former commander-in-chief in French Algeria), it took place from the afternoon of 21 to 26 April 1961 in the midst of the Algerian War (1954–1962). The organisers of the putsch were opposed to the secret negotiations that Prime Minister of France, French Prime Minister Michel Debré's government had started with the anti-colonialist National Liberation Front (Algeria), National Liberation Front ...

Gerboise Blanche (nuclear Test)
''Gerboise Blanche'' (or ''Opération Gerboise Blanche'') was the codename of the second French nuclear test. It was conducted by the Nuclear Experiments Operational Group (GOEN), a unit of the Joint Special Weapons Command on 1 April 1960, at the Saharan Military Experiments Centre near Reggane, French Algeria in the Sahara desert region of Tanezrouft, during the Algerian War. Name ''Gerboise'' is the French word for jerboa, a desert rodent found in the Sahara. The color white (''Blanche'') adjuncted is said to come from the second colour of the French Flag. Test Explosion ''Gerboise Blanche'' operation was carried out 3 months after the success of the first test, ''Gerboise Bleue''. Unlike the first attempt and the two others that were to come, this bomb was placed a few kilometres from ground zero, and detonated on a concrete pad. This was a voluntary act of the authorities as they feared the usual test site would have been too contaminated for the next tests. On 1 Apr ...

Gerboise Bleue (nuclear Test)
''Gerboise Bleue'' (; ) was the codename of the first French nuclear test. It was conducted by the Nuclear Experiments Operational Group (GOEN), a unit of the Joint Special Weapons Command on 13 February 1960, at the Saharan Military Experiments Centre near Reggane, French Algeria in the Sahara desert region of Tanezrouft, during the Algerian War. General Pierre Marie Gallois was instrumental in the endeavour, and earned the nickname of ''père de la bombe A'' ("father of the A-bomb"). Name ''Gerboise'' is the French word for jerboa, a desert rodent found in the Sahara. The color blue (''Bleue'') adjuncted is said to come from the first colour of the French Flag. Test Explosion On April 11, 1958, French Prime Minister Félix Gaillard ordered a nuclear test in the first quarter of 1960. President Charles de Gaulle reaffirmed the decision after the French Fourth Republic collapsed in the May 1958 crisis. On 13 February 1960 at 7:04:00 UTC, the plutonium filled bomb was de ...

SI Derived Unit
SI derived units are units of measurement derived from the seven base units specified by the International System of Units (SI). They can be expressed as a product (or ratio) of one or more of the base units, possibly scaled by an appropriate power of exponentiation (see: Buckingham π theorem). Some are dimensionless, as when the units cancel out in ratios of like quantities. The SI has special names for 22 of these derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m2), the SI derived unit of area; and the kilogram per cubic metre (kg/m3 or kg⋅m−3), the SI derived unit of density. The names of SI derived units, when written in full, are always in lowercase. However, the symbols for units named after persons are written with an uppercase initial letter. For example, the symbol for hertz is "Hz", while the symbol for metre is "m". Special names The International System of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray (unit)
The gray (symbol: Gy) is the unit of ionizing radiation dose in the International System of Units (SI), defined as the absorption of one joule of radiation energy per kilogram of matter. It is used as a unit of the radiation quantity absorbed dose that measures the energy deposited by ionizing radiation in a unit mass of matter being irradiated, and is used for measuring the delivered dose in radiotherapy, food irradiation and radiation sterilization. It is important in predicting likely acute health effects, such as acute radiation syndrome and is used to calculate equivalent dose using the sievert, which is a measure of the stochastic health effect on the human body. The gray is also used in radiation metrology as a unit of the radiation quantity kerma; defined as the sum of the initial kinetic energies of all the charged particles liberated by uncharged ionizing radiation in a sample of matter per unit mass. The gray is an important unit in ionising radiation measuremen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rad (unit)
The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg. It was originally defined in CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter. The material absorbing the radiation can be human tissue or silicon microchips or any other medium (for example, air, water, lead shielding, etc.). It has been replaced by the gray (Gy) in SI derived units, but is still used in the United States, although this is "strongly discouraged" in Chapter 5.2 of the ''Guide to the SI'', which was written and published by the U.S. National Institute of Standards and Technology. However, the numerically equivalent SI unit, the centigray, is widely used to report absorbed doses within radiotherapy. The roentgen, used to quantify the radiation exposure, may be related to the corresponding absorbed dose by use of the F-factor. Health effects A dose of under 100 rad will typically produce no immediate symptoms other than blood ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Fallout
Nuclear fallout is the residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. The amount and spread of fallout is a product of the size of the weapon and the altitude at which it is detonated. Fallout may get entrained with the products of a pyrocumulus cloud and fall as black rain (rain darkened by soot and other particulates, which fell within 30–40 minutes of the atomic bombings of Hiroshima and Nagasaki). This radioactive dust, usually consisting of fission products mixed with bystanding atoms that are neutron-activated by exposure, is a form of radioactive contamination. Types of fallout Fallout comes in two varieties. The first is a small amount of carcinogenic material with a long half-life. The second, depending on the height of detonation, is ...
