Uranium (92U) is a naturally occurring radioactive element (radioelement) with no stable isotopes. It has two primordial isotopes, uranium-238 and uranium-235...

Uranium mining is the process of extraction of uranium ore from the ground. Over 50,000 tons of uranium were produced in 2019. Kazakhstan, Canada, and...

The released neutrons then cause fission of other uranium atoms, until all of the available uranium is exhausted. This is called a chain reaction. Artificial...

About 0.7% of natural uranium is 235 U, which will undergo fission by both fast and slow (thermal) neutrons. When the uranium undergoes fission, it releases...
