What is Uranium Used For?
Apr 19, · Civilian Uses: The major use of uranium in a non-military capacity is in nuclear power plants. It is used to fuel the nuclear fission Before people knew that uranium was radioactive it was used as a yellow coloring for pottery and glassware. It was also Uranium was used in photographic. Jul 07, · Uranium is not only useful for nuclear power plants, but it is also useful for medical uses and radioactive dating. In medicine, many radioactive isotopes used for diagnosis or treatment, such as X-ray and radiotherapy for cancer patients, are made from uranium. .
Uranium is a silvery-grey metal that is radioactive. It is the ninety-second element on the periodic table. It is a weakly radioactive element whose half-live ranges fromyears to 4. Martin Klaproth discovered this element while he was uraanium in his laboratory in in Germany. Martin precipitated sodium-diuranate yellow compound by melting uraninite in nitric acid. He neutralized the mixture by adding sodium-hydroxide. Martin assumed that the yellow compound was an oxide of arre undiscovered metal and he heated it to extract a black powder.
The black powder which Martin extracted was an oxide of uranium. Martin concluded that the black powder was a newly discovered metal which he named after Uranus. Peligot Eugene became the first human being to isolate uranium in when he heated uranium-tetrachloride with potassium.
Becquerel Henri discovered radioactivity in when he left a potassium uranyl-sulfate on a photographic plate in a drawer.
Henri noticed that the plate became fogged and concluded that uranium emitted some rays that affected the plate. Uranium is a crucial compound that is used to power the nuclear power plants which generate electricity. Theoretically, a kilogram of Uranium produces over 20terajoules of energy. The chemical-reaction is controlled by various nuclear-absorbing materials.
The energy produced by Uranium creates steam that turns the turbines in the power plant which generate electricity. Uranium can easily decay how to grow new guinea impatiens a breeder reactor to form plutonium Plutonium can sustain chemical reactions.
The only naturally-occurring isotope that whay maintain a reaction is Uranium In the military, this element can be used to create high-density penetrators ammunition. At very high speed this ammunition can destroy a heavily armored target. Removable vehicle armors and tank armors are whst hardened by the DU plates. The DU is also added to the shielding materials of various container that transport and store radioactive materials. Even though the DU is radioactive, its hardness makes it effective for stopping radiation from various strong radioactive materials than lead.
DU is preferred over other dense elements because of its ability to be easily cast and its low price. The usage of this metal dates back to 79CE when people used it in the glazing industry. Uranium is used in the wood and leather industry for dyes and stain, in photographic chemicals, and in making the filament of the stage-lighting bulbs.
Uranium salts are the dye fixatives of wool or silk. The discovery of radioactivity introduced a new usage of uranium in science. The long half-life of uranium isotopes made it possible to estimate the age of an igneous rock. A piece of uranium ore. Geoffrey Migiro June 25 in World Facts. Olympic Games History.

The Uses Of Uranium
Uses. Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations. It is also the major material from which other synthetic transuranium elements are made. Naturally occurring uranium consists of 99% uranium and 1% uranium Martin Heinrich Klaproth. There were no major uses of uranium until when it was discovered that uranium could emit beta rays when inundated with neutrons. Enrico Fermi was the man in charge of the team that had this discovery, and they were excited by the potential energy that.
Institute for Energy and Environmental Research For a safer, healthier environment and the democratization of science. First discovered in the 18th century, uranium is an element found everywhere on Earth, but mainly in trace quantities. In , German physicists Otto Hahn and Fritz Strassmann showed that uranium could be split into parts to yield energy. Uranium is the principal fuel for nuclear reactors and the main raw material for nuclear weapons.
Natural uranium consists of three isotopes: uranium, uranium, and uranium Uranium isotopes are radioactive. The nuclei of radioactive elements are unstable, meaning they are transformed into other elements, typically by emitting particles and sometimes by absorbing particles. This process, known as radioactive decay, generally results in the emission of alpha or beta particles from the nucleus. It is often also accompanied by emission of gamma radiation, which is electromagnetic radiation, like X-rays.
These three kinds of radiation have very different properties in some respects but are all ionizing radiation—each is energetic enough to break chemical bonds, thereby possessing the ability to damage or destroy living cells.
Uranium, the most prevalent isotope in uranium ore, has a half-life of about 4. Uranium decays by alpha emission into thorium, which itself decays by beta emission to protactinium, which decays by beta emission to uranium, and so on. After several more alpha and beta decays, the series ends with the stable isotope lead Uranium emits alpha particles which are less penetrating than other forms of radiation, and weak gamma rays As long as it remains outside the body, uranium poses little health hazard mainly from the gamma-rays.
If inhaled or ingested, however, its radioactivity poses increased risks of lung cancer and bone cancer. Uranium is also chemically toxic at high concentrations and can cause damage to internal organs, notably the kidneys. Animal studies suggest that uranium may affect reproduction, the developing fetus,  and increase the risk of leukemia and soft tissue cancers. The property of uranium important for nuclear weapons and nuclear power is its ability to fission, or split into two lighter fragments when bombarded with neutrons releasing energy in the process.
Of the naturally-occuring uranium isotopes, only uranium can sustain a chain reaction— a reaction in which each fission produces enough neutrons to trigger another, so that the fission process is maintained without any external source of neutrons. Traditionally, uranium has been extracted from open-pits and underground mines. In the past decade, alternative techniques such in-situ leach mining, in which solutions are injected into underground deposits to dissolve uranium, have become more widely used.
Most mines in the U. The milling refining process extracts uranium oxide U 3 O 8 from ore to form yellowcake, a yellow or brown powder that contains about 90 percent uranium oxide. In-situ leach mining leaves the unusable portion in the ground, it does not generate this form of waste. The total volume of mill tailings generated in the U. Moreover, the half-lives of the principal radioactive components of mill tailings, thorium and radium are long, being about 75, years and 1, years respectively.
The most serious health hazard associated with uranium mining is lung cancer due to inhaling uranium decay products. Uranium mill tailings contain radioactive materials, notably radium, and heavy metals e.
Mining and milling operations in the U. For example, nearly one third of all mill tailings from abandoned mill operations are on lands of the Navajo nation alone.
Others continue to suffer the effects of land and water contamination due to seepage and spills from tailings piles. Uranium is generally used in reactors in the form of uranium dioxide UO 2 or uranium metal; nuclear weapons use the metallic form. Production of uranium dioxide or metal requires chemical processing of yellowcake.
Further, most civilian and many military reactors require uranium that has a higher proportion of uranium than present in natural uranium.
The process used to increase the amount of uranium relative to uranium is known as uranium enrichment. Some research reactors and all U. To enrich uranium, it must first be put in the chemical form uranium hexafluoride UF 6. After enrichment, UF6 is chemically converted to uranium dioxide or metal. A major hazard in both the uranium conversion and uranium enrichment processes comes from the handling of uranium hexafluoride, which is chemically toxic as well as radioactive.
Moreover, it reacts readily with moisture, releasing highly toxic hydrofluoric acid. Conversion and enrichment facilities have had a number of accidents involving uranium hexafluoride. The bulk of waste from the enrichment process is depleted uranium—so-called because most of the uranium has been extracted from it.
Depleted uranium has been used by the U. It was incorporated into these conventional weapons without informing armed forces personnel that depleted uranium is a radioactive material and without procedures for measuring doses to operating personnel. The enrichment process can also be reversed. Uranium metal at various enrichments must be chemically processed so that it can be blended into a homogeneous material at one enrichment level.
As a result, the health and environmental risks of blending are similar to those for uranium conversion and enrichment. In the federal government set standards for controlling pollution from active and abandoned mill tailings piles resulting from yellowcake production. The principal goals of federal regulations are to limit the seepage of radionuclides and heavy metals into groundwater and reduce emissions of radon to the air. Mandatory standards for decommissioning nuclear facilities including conversion and enrichment facilities are only now being developed by the U.
Environmental Protection Agency and the U. So far, the NRC has been using guidelines developed by its staff in to oversee decommissioning efforts. Uranium and associated decay products thorium and radium will remain hazardous for thousands of years. Current U. This means that future generations—far beyond those promised protection by these regulations—will likely face significant risks from uranium mining, milling, and processing activities.
