Plutonium is a rare earth element, so called because it is only found in trace amounts in the earth’s crust it is radioactive and has a silvery colour, but degrades to a dull grey, olive or yellow when it oxidises. Overview in every uranium-based nuclear reactor core there is both fission of uranium isotopes such as uranium-235, mox fuel, consisting of 7% plutonium mixed with depleted uranium, is equivalent to uranium oxide fuel enriched to about 45% 235 92 u, assuming that the plutonium has about 60–65% 239 94 pu.

Plutonium is poorly absorbed by inhalation, ingestion, or dermal exposure the degree of absorption is determined by valence state and solubility of the plutonium compound, with hexavalent and chelated forms being more readily absorbed into the blood from alveoli. With the production of 50 grams of plutonium-238, researchers at the department of energy's oak ridge national laboratory have restored a us capability dormant for nearly 30 years and set the course to provide power for nasa and other missions.

Plutonium-240 is the second most common isotope, formed by neutron capture by pu-239 in about one-third of impacts its concentration in nuclear fuel builds up steadily, since it does not undergo fission to produce energy in the same way as pu-239. Plutonium was discovered in 1941 but, owing to wartime security measures in place at the time, the announcement of its discovery was delayed until 1946 it is a man-made or transuranium element of the actinide or actinoid series of rare earth elements.
