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 ...

There are three isotopes of uranium: U-238, U-235, and U-234. Uranium decays naturally, and highly active isotopes are now in short supply. Apparently, whatever process created the uranium on ...

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 ...

LIS Technologies, which stands for Laser Isotope Separation, is developing lasers to excite and extract the uranium-235 ...

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 ...
