Energy content of uranium 238
WebPlutonium-239 (239 Pu or Pu-239) is an isotope of plutonium.Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 is also used for that purpose. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and … WebThe uranium hexafluoride is fed into centrifuges, with thousands of rapidly-spinning vertical tubes that separate uranium-235 from the slightly heavier uranium-238 isotope. The centrifuges separate the uranium into two streams: one stream is enriched in uranium-235; the other consists of ‘tails’ containing a lower concentration of uranium ...

WebApr 12, 2024 · Decay chain of uranium-238, with radon near the middle. That’s what the progeny (decay products) of radon do. They’re electrically charged, so they stick to the alveoli in the lungs. The decay products polonium-218 and polonium-214 are believed to cause most of the lung cancer from houses with high radon levels. Why test for radon? WebNov 1, 2024 · Pu-238 has a half-life of 87.7 years, making it a much longer-lasting source of energy than polonium-210, which was used in the 1959 RTG prototype and has a half-life of 138 days. Pu-238 exhibits high heat density and emits primarily alpha particles, which are easily shielded; this makes it safer to handle than most other radioactive materials.
