Investing in Plutonium

Plutonium is a radioactive actinide and the element used in modern nuclear weapons. Plutonium-238 is an alpha emitter with a 87 year half-life, making it an excellent choice for radioisotope thermoelectric generators, the nuclear power plants that power long distance spacecraft.

Almost all plutonium is manufactured synthetically by bombarding uranium-238 with neutrons in a nuclear reactor. Thus it could probably be indirectly invested in by investing in uranium.
