uranium 235- a uranium isotope with mass number 235; capable of sustaining chain reactions uranium 238- the commonest isotope of uranium; it is not fissionable but when irradiated with neutrons it produces fissionable plutonium 239 pitchblende,uraninite- a mineral consisting of uranium oxide and ...
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...
P. Rodriguez, in Encyclopedia of Materials: Science and Technology, 2001 2.2 Uranium Enrichment Eighty five percent of the nuclear electricity (which is ∼17% of the total electricity generation in the world today) comes from light water reactors (LWRs) which needs enrichment in U-235 to abo...
Non-neutron nuclear data (half-lives, transition intensities, radiation energies and emission probabilities) have been evaluated for the radionuclides constituting the decay chain of uranium-238. A selection of the many recommended data are presented that may be useful in several applications (e.g. ...
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...
238.0289, occurring mainly in pitchblende and notable for its two isotopes: 238U and 235U (99.2745% and 0.720%, respectively, the rest being made up by 234U), 235U being the first substance ever shown capable of supporting a self-sustaining chain reaction. [G. myth. character, Uranus] ...
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-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...
