QUE SIGNIFIE URANIUM EN ANGLAIS

Uranium

Uranium

L'uranium est un élément chimique métallique blanc argenté dans la série des actinides de la table périodique, avec le symbole U et le numéro atomique 92. Un atome d'uranium a 92 protons et 92 électrons, dont 6 sont des électrons de valence. L'uranium est faiblement radioactif car tous ses isotopes sont instables. Les isotopes les plus courants de l'uranium sont l'uranium-238 et l'uranium-235. L'uranium possède le deuxième poids atomique le plus élevé des éléments primordiaux, plus léger que le plutonium. Sa densité est d'environ 70% supérieure à celle du plomb, mais pas aussi dense que l'or ou le tungstène. Il se produit naturellement à de faibles concentrations de quelques parties par million dans le sol, la roche et l'eau, et est extrait commercialement de minéraux contenant de l'uranium tels que l'uraninite. Dans la nature, l'uranium se trouve comme l'uranium-238, l'uranium-235 et une très petite quantité d'uranium-234. L'uranium s'écroule lentement en émettant une particule alpha. La demi-vie de l'uranium-238 est d'environ 4,47 milliards d'années et celle de l'uranium-235 est de 704 millions d'années, ce qui les rend utiles à l'âge de la Terre. De nombreuses utilisations contemporaines de l'uranium exploitent leurs propriétés nucléaires uniques.

Uranium is a silvery-white metallic chemical element in the actinide series of the periodic table, with symbol U and atomic number 92. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all its isotopes are unstable. The most common isotopes of uranium are uranium-238 and uranium-235. Uranium has the second highest atomic weight of the primordially occurring elements, lighter only than plutonium. Its density is about 70% higher than that of lead, but not as dense as gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238, uranium-235, and a very small amount of uranium-234. Uranium decays slowly by emitting an alpha particle. The half-life of uranium-238 is about 4.47 billion years and that of uranium-235 is 704 million years, making them useful in dating the age of the Earth. Many contemporary uses of uranium exploit its unique nuclear properties.

définition de uranium dans le dictionnaire anglais

La définition de l'uranium dans le dictionnaire est un élément métallique radioactif blanc-argenté de la série des actinides. Il est présent dans plusieurs minéraux, notamment la pechblende, la carnotite et l'autunite. Il est principalement utilisé comme source d'énergie nucléaire par fission du radio-isotope uranium-235. Symbole: U; numéro atomique: 92; poids atomique: 238,0289; demi-vie de l'isotope le plus stable, 238U: 451 × 109 ans; valence: 2-6; densité relative: 18,95; point de fusion: 1135 ° C; point d'ébullition: 4134 ° C.

Yukiya Amano

Satellite images suggest North Korea is building a light-water reactor and working on uranium enrichment. This is troubling.

Hans Blix

They have been saying for a long time that Iraq made an effort to import active uranium, and my colleague demonstrated the other day that they came to the conclusion that it was a fake document that everybody is relying upon.

3

Bob Brown

There are better alternatives... Australia should be exporting its solar technology, not its uranium.

4

Michael Burgess

Nuclear power is here to stay, and we need to support a strong domestic uranium industry.

5

Barton Gellman

At the height of Iraq's clandestine nuclear weapons program, which nearly succeeded in building a bomb in 1991, Tuwaitha incorporated research reactors, uranium mining and enrichment facilities, chemical engineering plants and an explosives fabrication center to build the device that detonates a nuclear core.

6

Jim Gerlach

In addition, it is very likely that United States action in Iraq caused Iran to open its nuclear facilities for international inspection and suspend its uranium enrichment activities.

7

James Hansen

With a fourth generation of nuclear power, you can have a technology that will burn more than 99 percent of the energy in the fuel. It would mean that you don't need to mine uranium for the next thousand years.

8

John Holdren

I think we ultimately ought to look to put all uranium enrichment and fuel reprocessing, if any is done, under multinational control. Those are the two technologies by which nuclear energy can be translated into nuclear weapons programmes.

9

Garik Israelian

Connection between life and radioactive nuclei is straightforward. No life without tectonic activity, without volcanic activity. And we know very well that geothermal energy is mostly produced by decay of uranium, thorium, and potassium.

10

Winona LaDuke

Native people - about two-thirds of the uranium in the United States is on indigenous lands. On a worldwide scale, about 70 percent of the uranium is either in Aboriginal lands in Australia or up in the Subarctic of Canada, where native people are still fighting uranium mining.
