Greg Klunder, a chemist in LLNL's Forensic Science Center, examines a uranium ore concentrate sample with the aid of a near-infrared spectrometer.

What would happen if I touched uranium? originally appeared on Quora – the knowledge sharing network where compelling questions are answered by people with unique insights. Answer by Paul Wicks ...

Uranium occurs naturally in three isotopes (forms with different masses): 234, 235, and 238. Only uranium-235—which constitutes a mere 0.72 percent of an average uranium ore sample—can trigger ...

Normally on Earth, uranium-235 makes up about 0.7255% of uranium isotopes in a sample – whereas the Oklo sample contained about half that amount. Remarkable precision Also, by tracking the different ...

Once we learned you could indeed buy tiny traces of uranium online, we immediately flocked to Amazon, where the bestseller is this Uranium Ore sample from Images Scientific Instruments, Inc ...

Researchers are trying to find out why uranium persists in groundwater at former uranium ore processing sites despite remediation of contaminated surface materials two decades ago. They think ...

To separate the tiny quantity of uranium-235 that is present in every natural sample of uranium ore, engineers first use a chemical reaction to turn the uranium into a gas, said Jeff Binder, the ...

If you're looking for stocking stuffers, tanks and 900-pound ukelele bands won't do. Why not try an attractively packaged bit of uranium ore? This lovely little tin is wrapped in a yellow and red ...

He heard them say, in Spanish, that it was a sample of uranium ore, and that the Government was offering a $10,000 prize to prospectors who made a big strike.

The least common isotope is uranium-234, which forms as uranium-238 decays. Neither of these products are fissile, meaning their atoms don’t easily split, so they can’t sustain a nuclear chain ...

A sample of yellowcake—a partially refined form of uranium often used in making nuclear weapons. A hundred kilograms of uranium ore yields just 37 grams of yellowcake. Pallava Bagla/Getty Images ...

Engineers first use a chemical reaction to turn a sample of mined uranium ore (consisting of both uranium-238 and uranium-235 isotopes) into a gas. Centrifuges then spin the gas at high speeds.
