urániumot

Urániumot is the Hungarian word for uranium. Uranium is a chemical element with the symbol U and atomic number 92. It is a dense, silvery-white, radioactive metal. Naturally occurring uranium is composed primarily of three isotopes: uranium-238, uranium-235, and uranium-234. Uranium-238 is the most abundant isotope, making up about 99.3% of naturally occurring uranium. Uranium-235, while less abundant at about 0.7%, is significant because it is fissile, meaning it can sustain a nuclear chain reaction.

Uranium is found in small amounts in most rocks and soils, as well as in water. It is extracted from ores, primarily through mining. The primary uses of uranium are as fuel for nuclear power plants and in the production of nuclear weapons. The controlled fission of uranium-235 in nuclear reactors generates heat, which is used to produce electricity. In nuclear weapons, an uncontrolled chain reaction of fissile isotopes releases a tremendous amount of energy.

Uranium is also used in some medical applications, such as in certain diagnostic imaging techniques. Due to its radioactivity, uranium and its compounds must be handled with care to prevent exposure and contamination. The long-term storage of radioactive waste generated from nuclear processes is a significant environmental and safety concern associated with uranium utilization.
