WebArtificial isotopes 233U. 233 U belongs to the group of fissile isotopes. It is produced by radiative neutron capture in nuclear reactors containing thorium fuel. 233 U decays via alpha decay into 229 Th with a half-life of 159 200 years. 233 U occasionally decays by spontaneous fission with a very low probability of 0.000000006%. WebThere are 27 known isotopes of uranium ranging in atomic weights 217–219, 222–240 and 242, with half-lives of from billions of years to a few nanoseconds. Naturally occurring uranium consists of three major isotopes: 238 U (99.28% abundance), 235 U (0.71%), and 234 U (0.0054%). birth control after pregnancy breastfeedingWebU-235 is the only naturally occurring isotope which is thermally fissile, and it is present in natural uranium at a concentration of 0.7%. U-238 and Th-232 are the main naturally-occurring fertile isotopes. The probability that fission or any another neutron-induced reaction will occur is described by the neutron cross-section for that reaction. danielle thorne author
