Natural isotopes of uranium are U-238, U235, and U-234 (see table above for natural abundances). Depleted uranium contains less of the isotopes U-235 and U-234. The specific activity of depleted ...

Uranium-238 is uranium’s most relatively abundant isotope, making up 99 percent of the naturally occurring form of the element. However, unlike the scarce and radioactive uranium-235 isotope ...

The International Atomic Energy Agency (IAEA) defines uranium as a Low Specific Activity material. In its natural state, it consists of three isotopes (U-234, U-235 and U-238). Other isotopes that ...

This isotope of hydrogen is called deuterium ... In its natural state, common uranium (U-238) can't generate destructive nuclear explosions. It either must be enriched—made more concentrated ...

A highly coveted children's toy from the 1950s is going on sale—and it contains real uranium. The Gilbert U-238 Atomic Energy Laboratory, which was released in 1950, was dubbed one of 'the 10 ...

Uranium has two main naturally occurring isotopes - uranium-235, with 92 protons and 143 neutrons, and uranium-238, with 92 protons and 146 neutrons. Those three neutrons make a huge difference.

and the time it takes for one-half of a particular isotope to decay is its radioactive half-life. For example, about 1.5 percent of a quantity of Uranium 238 will decay to lead every 100 million ...

Different isotopes of a single chemical element are distinguished ... SRS produced the Pu-239 from a combination of uranium-235 (U-235) and U-238 in the reactors. U-235 in this “fuel” released ...

As the city of Oak Ridge races to once again be the U.S. capital of uranium enrichment, one company hopes to commercialize a ...

Uranium is a dense element and a key ingredient in nuclear weapons production. It occurs naturally in ores and minerals and has a few important isotopes. U-238 makes up about 99.27% of natural ...
