CHE SIGNIFICA URANIUM IN INGLESE
Uranio
L'uranio è un elemento chimico metallico argentato bianco nella serie actinide della tavola periodica, con simbolo U e numero atomico 92. Un atomo di uranio ha 92 protoni e 92 elettroni, di cui 6 elettroni di valenza. L'uranio è debolmente radioattivo perché tutti i suoi isotopi sono instabili. Gli isotopi più comuni di uranio sono l'uranio-238 e l'uranio-235. L'uranio ha il secondo peso atomico più alto degli elementi primordialmente presenti, più leggeri di plutonio. La sua densità è di circa il 70% superiore a quella del piombo, ma non denso come l'oro o il tungsteno. Si verifica naturalmente in basse concentrazioni di poche parti per milione nel suolo, nella roccia e nell'acqua, ed è commercialmente estratto da minerali contenenti uranio come uranitina. In natura, l'uranio è trovato come uranio-238, uranio-235 e una piccola quantità di uranio-234. L'uranio decade lentamente emettendo una particella alfa. La metà dell'uranio-238 è di circa 4.47 miliardi di anni e quella dell'uranio-235 è di 704 milioni di anni, rendendoli utili per datare l'età della Terra. Molti usi contemporanei di uranio sfruttano le sue proprietà nucleari uniche.
definizione di uranium nel dizionario inglese
La definizione di uranio nel dizionario è un elemento metallico bianco-argenteo radioattivo della serie degli attinidi. Si verifica in diversi minerali tra cui pechblenda, carnotite e autunite ed è usato principalmente come fonte di energia nucleare mediante la fissione del radioisotopo uranio-235. Simbolo: U; numero atomico: 92; atomico: 238.0289; emivita dell'isotopo più stabile, 238U: 451 × 109 anni; valenza: 2-6; densità relativa: 18,95; punto di fusione: 1135 ° C; punto di ebollizione: 4134 ° C.

Satellite images suggest North Korea is building a light-water reactor and working on uranium enrichment. This is troubling.
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.
There are better alternatives... Australia should be exporting its solar technology, not its uranium.
Nuclear power is here to stay, and we need to support a strong domestic uranium industry.
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.
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.
