WebPu-239 emits alpha particles to decay to U-235 (see Appendix 2 ). Its half-life is 24,390 years, therefore it has a low level of radioactivity. Pu-240 emits alpha particles as it decays to U-236 (another non-fissile isotope). Its half-life is 6600 years, therefore it has a higher level of radioactivity than Pu-239. WebUranium-238 (238 U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor.However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239. 238 U … sharepoint filtered lookup field https://jpbarnhart.com
