More common than gold, uranium is abundant on Earth. But less than one percent of the naturally occurring element is useful for nuclear power.

What is depleted uranium? Uranium, symbolized by the letter U, is a naturally occurring element that is radioactive. Natural uranium is composed primarily of three isotopes: U-234, U-235 and U-238.

There are other uses of uranium apart from nuclear weapons as discussed in this article. Uranium is a silver-grey metal that is radioactive. The most common types are uranium 235 and uranium 238. The ...

When Israeli aircraft recently struck a uranium-enrichment complex in the nation, Iran could have been days away from achieving “breakout,” the ability to quickly turn “yellowcake” uranium ...

The U-bomb, say the educated guessers, gets much of its energy from uranium 238, the plentiful isotope of uranium that used to be considered inert and nonfissionable.

Isotopes of natural uranium decay by emitting mainly alpha particles. The emission of beta particles and gamma radiations are low. The table below shows the average energies per transformation emitted ...

Not that anyone asked, but uranium enrichment is certainly a newsworthy topic where a little science might be helpful. Here's ...

The U.S. sent 238 Venezuelan migrants to a Salvadoran mega-prison. The Trump administration says they're all gang members, but 60 Minutes could find no criminal records for 75% of them.

Eastern Libyan forces said on Thursday that 10 drums of uranium declared missing by the U.N. nuclear watchdog had been found near the warehouse they were taken from in southern Libya.

OAK RIDGE, Tenn. — Y-12 National Security Complex said it is back to normal operations after responding to a fire at a uranium processing building. Y-12 initially said it was responding to an ...

U-238 decays very slowly or is barely radioactive, but the heat it produces is enough to warm Earth’s core. U-235 decays a bit faster or is more radioactive than U-238.

Depleted uranium munitions are bad news for enemy tanks, but are not nuclear weapons, and studies have shown that they pose low risks of radiation or chemical exposure.
