    15. Plutonium. Cost: $4,400-$5,600 per gram. The devastating power of nuclear weapons, such as those used on Japan in World War II, probably makes plutonium more well-known than it otherwise might be.

  4. Plutonium - Wikipedia

    en.wikipedia.org/wiki/Plutonium

    Trace amounts of plutonium-238, plutonium-239, plutonium-240, and plutonium-244 can be found in nature. Small traces of plutonium-239, a few parts per trillion , and its decay products are naturally found in some concentrated ores of uranium, [ 54 ] such as the natural nuclear fission reactor in Oklo , Gabon . [ 55 ]

    en.wikipedia.org/wiki/Radioisotope...

    Plutonium extracted from spent nuclear fuel has a low share of Pu-238, so plutonium-238 for use in RTGs is usually purpose-made by neutron irradiation of neptunium-237, further raising costs. Caesium in fission products is almost equal parts Cs-135 and Cs-137, plus significant amounts of stable Cs-133 and, in "young" spent fuel, short lived Cs-134.

  6. Plutonium-238 - Wikipedia

    en.wikipedia.org/wiki/Plutonium-238

    Plutonium-238 (238 Pu or Pu-238) is a radioactive isotope of plutonium that has a half-life of 87.7 years.. Plutonium-238 is a very powerful alpha emitter; as alpha particles are easily blocked, this makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units.

  9. Plutonium-239 - Wikipedia

    en.wikipedia.org/wiki/Plutonium-239

    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 uranium-233. Plutonium-239 has a half-life of 24,110 years. [1]
