The isotope number is written after the element abbreviation (ex-isotope 238 is written Pu-238). The first isotope of Plutonium, Pu-238, was created by bombarding uranium with deuterons in a cyclotron at Seaborg's lab in California and the second, Pu-239 was created in a similar fashion by Seaborg, in 1941. Of the isotopes, Pu-239 is considered most valuable for it can be used as fuel in nuclear reactors and nuclear weapons.

The heat produced by decaying Pu-238 is used as the heat source with a thermocouple. As can be seen in Fig. 2, fins serve as heat sinks to create a voltage across the thermocouple. Thus, the temperature gradient needed for the Seebeck Effect in Curiosity's RTG, results from hot Pu-238 and the cold atmosphere of Mars. Powering Space Travel

The coarse-grained, Ca-rich inclusions in the Allende meteorite are the highest-temperature condensates from the cooling solar nebula and, as such, the oldest solid objects in the solar system. All refractory elements with condensation points above the accretion temperature of the inclusions whose concentrations in them have been measured are seen to be present in the inclusions in

Plutonium-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 and radioisotope heater units. The density of plutonium-238 at room temperature is about 19.8 g/cc.
