2/27/2024 0 Comments Uranium atomic massBut a very small amount gets accumulated in the bones. Most of the Uranium-238 ingested or inhaled usually leaves the body. However, it cannot harm an organism from the outside as its Alpha radiation does not penetrate the skin. It can enter the body through inhalation, ingestion and sometimes through open wounds. Radioactive Uranium can be found in nature which can cause health problems for humans. It is used to produce Mixed Oxide Fuel (MOX) along with Plutonium- 239. Enriched Uranium is downblended with the help of depleted Uranium for using it as commercial nuclear fuel. Downblendingĭownnblending is the opposite process of enriching. It is used in thermonuclear weapons for the purpose of encasing the fusion fuel which helps to make the weapon more powerful. Its function is to reduce the required critical mass and make the weapon work more efficiently. Uranium-238 is used as a “tamper” material in nuclear weapons. Thorium) in the object with the amount of the parent isotope (e.g. In this process, the age of an object is determined by adding the amount of the daughter product (e.g. The whole decay series happens at a constant rate which helps to correctly date rocks and minerals. ![]() The decay chain of this isotope is well documented with Lead being the final stable element. Uranium-238 is used in this dating process. The radioactive property of a material is applied to determine the age of objects like rocks and fossils. Researchers are trying to find out whether Uranium Dioxide concretes can be used as a Cask Storage material for storing radioactive waste. However, it cannot stop fast neutrons having a speed of 14,000 km/s, as effectively as ordinary water. The high atomic weight and electron numbers of this material can efficiently absorb Gamma Rays and X Rays. The non-radioactive casing of the Shield can easily stop its Alpha radiation from causing any harm. It is used as a shield against harmful radiation in the form of Depleted Uranium Dioxide and Depleted Uranium. This technology is used in many experimental nuclear reactors. It produces fissile products like Plutonium- 239, which is used as a nuclear fuel to produce high amounts of energy. As Breederįertile uranium-238 isotope is used in Breeder Reactors for its neutron capture ability. These properties make this substance useful in various industries. The Depleted Uranium (DU) is very heavy having a high density level. This radioactive metal has a very long half life. This final radioactive isotope is highly useful in power plants. It collides with a neutron and turns into Uranium 239, which undergoes decay and produces Plutonium-239. This material does not undergo fission unless struck by a high energy neutron. Uranium-238 has a very long half life of 4.468 billon years. ![]() Half life is the time period taken by a radioactive substance to decay and reduce to the half of its original amount. One atom of this substance contains 92 protons and 145 neutrons. This series is also known as “ Radium Series”. All the above elements are present (even if for a short time) in any sample containing Uranium be it metal, mineral or compound. Lead (stable) is the final element of this Alpha decay process. It means Thorium-234 is the daughter nuclide of this isotope. Thorium-234 is the next radioactive substance in the decay process of Uranium-238. Due to this reason it has been denoted by an Alpha particle in the second reaction. In the first equation the 4 2He ( Helium) is similar to an Alpha particle having mass number of 4 and atomic number 2. The above equation can also be denoted as Uranium-238 Decay Equationįollowing is the equation for the Alpha (α) radiation of this isotope: ![]() ![]() This isotope undergoes Alpha decay by emitting Alpha rays. This process is called the Radioactive decay. The unstable atomic nucleus of Uranium-238 emits ionizing particles and loses energy in order to achieve a stable state.
