In plutonium
…detected (1941) as the isotope plutonium-238 by American chemists Glenn T. Seaborg, Joseph W. Kennedy, and Arthur C. Wahl, who produced it by deuteron bombardment of uranium-238 in the 152-cm (60-inch) cyclotron at Berkeley, California. The element was named after the then planet Pluto. Traces of plutonium have subsequently been…

In transuranium element: Practical applications of transuranium isotopes
Three other transuranium isotopes—plutonium-238, americium-241, and californium-252—have demonstrated substantial practical applications. One gram of plutonium-238 produces approximately 0.57 watt of thermal power, primarily from alpha-particle decay, and this property has been used in space exploration to provide energy for small thermoelectric-power units.
