The decay chain of 238 U is commonly called the "radium series" (sometimes "uranium series"). Beginning with naturally occurring uranium-238, this series includes the following elements: …

Uranium-238 also decays by spontaneous fission. The symbols α and β indicate alpha and beta decay, and the times shown are half-lives. An asterisk indicates that the isotope is also a …

Graphic representation of the uranium-radium series, the natural radioactive decay series of the uranium isotope U-238. Direct parent isotopes are: 242 Pu, 238 Pa. Nuclear isomers or …

Apr 17, 2024 · Uranium-238 (U-238) Half-life: 4.47 billion years. Mode of decay: Alpha particles. Chemical properties: Weakly radioactive, extremely dense metal (65% denser than lead) …

Uranium-238 Radioactive Decay. The unstable atomic nucleus of Uranium-238 emits ionizing particles and loses energy in order to achieve a stable state. This process is called the …

Uranium-Thorium dating is based on the detection by mass spectrometry of both the parent (234 U) and daughter (230 Th) products of decay, through the emission of an alpha particle. The …
