Uranium-235 - Wikipedia
网页Uranium-235 (235 U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years.

网页Detailed decay information for the isotope uranium-235 including decay chains and daughter products.
网页Uranium, radium, and thorium occur in three natural decay series, headed by uranium-238, thorium-232, and uranium-235, respectively. In nature, the radionuclides in these three series are approximately in a state of secular equilibrium, in which the activities of all radionuclides within each series are nearly equal.
Decay chain - Wikipedia
网页In nuclear science a decay chain refers to the predictable series of radioactive disintegrations undergone by the nuclei of certain unstable chemical elements. Radioactive isotopes do not usually decay directly to stable isotopes, but …

Uranium-235 (U-235) | Definition, Uses, Half-Life, & Facts
网页2024年9月5日 · Uranium-235 constitutes about 0.72 percent of all naturally occurring uranium. (Most naturally occurring uranium is uranium-238.) It has a half-life of 704 million years, decaying to thorium-231, with the radioactive decay chain eventually ending in the stable isotope lead-207.
网页Radiological Properties (Daughter Products & Equilibrium) All of the uranium isotopes decay to shorter-lived decay products often referred to as “daughters.”. U-238 and U-235 together with their decay products form a “decay chain” or “series” the final decay product of which is a stable isotope of lead.
