Niger is the worlds largest exporter of uranium.
Iran says it is enriching uranium solely for the peaceful civilian purpose of generating electricity.
Previously, Washington had insisted that Teheran stop its uranium enrichment program as a precondition to face-to-face talks.
They were headed for Iran, one cable said, and were meant to control "uranium enrichment cascades" - the term for groups of spinning centrifuges.
Deep underneath your feet is a hellish stone soup, kept hot by a torrent of radiation from poisonous isotopes of uranium, thorium and potassium in the earth's superheated mantle.
Radium and uranium are radioactive elements.
One pound of uranium carries more releasable energy than 1,500 tons of coal.
While he pursues talks with Iran, Republicans fret, Iran's leaders chuckle behind their beards and carry on enriching uranium.
It can measure the gamma rays that the uranium emits when it spontaneously breaks up in pieces and energy is released we call that fission.
The meeting was the first of its kind since Tehran missed a deadline to respond to a package of incentives offered in October by western nations in exchange for Iran halting uranium enrichment.
Three workers at a uranium-processing plant in Tokaimura, then the center of the Japanese nuclear-power industry, improperly mixed a uranium solution. A blue flash heralded trouble.
The containment option is boosted by the belief that Iran is running out of uranium ore to convert and enrich.
The presence of water also helps to explain why most of the xenon now resides in grains of aluminum phosphate rather than in the uranium-rich minerals where fission first created these radioactive precursors.
The solution is then treated to precipitate uranium oxide.
The most ardent critic in Washington, DC, of the relic that favours the uranium business has been Nick Rahall.
Another allegedly vulnerable facility is the Gadwal uranium enrichment plant, less than 60 miles south of Buner district, where some of the fiercest clashes have taken place in recent days.
Significant health effects have been seen in uranium miners who are exposed to high levels of radon.
It includes epigenetic uranium impregnations in sandstone.
a highly fissionable isotope of plutonium that is used in atomic weapons and as a reactor fuel; produced by irradiating uranium 238 with slow electrons.
Inspectors from the International Atomic Energy Agency reported that they had found more unexplained traces of uranium in Syria, which still denies having a secret nuclear programme.
India is short of usable uranium. If it could buy foreign fuel for its civilian reactors, it could devote more of the stuff it makes at home to bomb-building.
A combinatin of sources of uranium may be the most realistic postulate.
When you split a uranium 235 atom you will create what we call fission fragments.
