239Pu is produced from the capture of epithermal neutrons in the resonances of 238U with subsequent β-decay. Other Pu isotopes are also formed, but their contribution to the overall fission yield is small. Fig. 1 presents measurements of Pu across a pellet cross-section for a thermal reactor...
Uranium-236 has a half-life of 2.342×107 years[4] and is not found in significant quantities in nature. The half-life of uranium-236 is too short for it to be primordial, though it has been identified as an extinct progenitor of its alpha decay daughter, thorium-232.[67] Uranium-236...
Uranium-238 is an α emitter, decaying through the 18-member uranium natural decay series into lead-206.[10] The decay series of uranium-235 (also called actino-uranium) has 15 members that ends in lead-207.[10] The constant rates of decay in these series makes comparison of the ratios...
Uranium-238 has a half-life of 4.468 billion years over which time it decays into stable lead-206. This process can be used to date ancient rocks by comparing the ratio of the isotope lead-206, the last isotope in the uranium decay series, to the level of uranium-238 in the sample of...

Uranium-235 undergoes spontaneous fission during radioactive decay; however, no standard equation can represent this reaction as its results are quite unpredictable. Uranium-235 Decay Chain The decay chain of this radioactive metal is known as the Actinium Series with thorium-231 being the next isot...
Uranium series radionuclides, polonium-210 and lead-210, in the lichen-caribou-wolf food chain of the Northwest Territories This report examines baseline concentrations and transfer of the uranium decay products polonium-210 and lead-210 in the lichen-caribou-wolf food chain at two locations in the...
