Plutonium-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 … See more The nuclear properties of plutonium-239, as well as the ability to produce large amounts of nearly pure Pu more cheaply than highly enriched weapons-grade uranium-235, led to its use in nuclear weapons See more Plutonium is made from uranium-238. Pu is normally created in nuclear reactors by transmutation of individual atoms of one of the isotopes of … See more Plutonium-239 emits alpha particles to become uranium-235. As an alpha emitter, plutonium-239 is not particularly dangerous as an external radiation source, but if it is ingested … See more In any operating nuclear reactor containing U, some plutonium-239 will accumulate in the nuclear fuel. Unlike reactors used to produce weapons-grade plutonium, commercial nuclear power reactors typically operate at a high burnup that allows a significant … See more • Teller-Ulam design See more WebPlutonium-238 is favored as a heat source because of its long half-line and no need for special shielding. However, its projected high cost, scarcity, and biological hazard encourages the search for a competitive material.

WebNov 7, 2024 · What happens when plutonium 239 decays? For example, the decay products of plutonium-238 and plutonium-239 are uranium- 234 and uranium-235. The decay process continues until a stable, non-radioactive decay product is formed. Radiation is released during the decay process in the form of alpha and beta particles and gamma radiation. WebJan 7, 2024 · There are five "common" isotopes of plutonium, Pu-238, Pu-239, Pu-240, Pu-241, and Pu-242.
