Uranium-238 - Wikipedia
Uranium-238 (238 U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor.
Uranium-238 - isotopic data and properties - ChemLin
Uranium-238 (Uranium I) is the radioisotope of the element Uranium, whose atomic nucleus has 146 neutrons in addition to the element-specific 92 protons, resulting in a mass number of 238. See also: list of Uranium isotopes. General data
Uranium-235 (U-235) and Uranium-238 (U-238) | Radiation Emergencies …
2024年4月17日 · U-235 and U-238 occur naturally in nearly all rock, soil, and water. U-238 is the most abundant form in the environment. U-235 can be concentrated in a process called “enrichment,” making it suitable for use in nuclear reactors or weapons.
Uranium 238 | Properties & Uses | nuclear-power.com
Uranium 238, which alone constitutes 99.28% of natural uranium, is the most common isotope of uranium in nature. Uranium 238 has the longest half-life (4.47×10 9 years), and therefore its abundance is so high. Uranium 238 is a fissionable isotope but is not a fissile isotope.
Uranium-238 | chemical isotope | Britannica - Encyclopedia Britannica
Uranium-238, for example, accounts for more than 99 percent of all naturally occurring uranium. In breeders, approximately 70 percent of this isotope can be utilized for power production. Conventional reactors, in contrast, can extract less than…
Uranium-238 Atomic Number, Fission, Decay, Half-Life, Uses
Uranium-238 is the main radioactive isotope of natural Uranium. It produces many other useful radioactive elements while undergoing decay. This makes this radioactive metal quite useful and valuable.
Isotopes of uranium - Wikipedia
Uranium-238 (238 U or U-238) is the most common isotope of uranium in nature. It is not fissile, but is fertile: it can capture a slow neutron and after two beta decays become fissile plutonium-239.
Difference Between U 235 and U 238 | Definition, Properties, Uses
2017年9月12日 · U-235 and U-238 are two radioactive isotopes of Uranium. The main difference between U-235 and U-238 is that the number of neutrons present in the U-235 nucleus is 143 whereas the number of protons present in the U-238 nucleus is 146.

Uranium-238 (U-238), is the most common isotope of uranium found in nature. When hit by a neutron , it becomes uranium-239 (U-239), an unstable element which decays into neptunium -239 (Np-239), which then itself decays, with a half-life of 2.355 days, into plutonium-239 (Pu-239).
