'''Neptunium''' ''(nep-TOO-nee-em)'' it a primarily synthetic [[element]] named after the planet Neptune (named after the Roman god of the sea), the next planet out from the Sun after Uranus. It was first produced by Edwin M. McMillian and Philip H. Abelson, in 1940. There are 25 known radioactive isotopes of this element. <ref>http://periodic.lanl.gov/93.shtml</ref>
==Uses==
Neptunium is used mainly for research purposes, since it does not have many commercial applications. It is sometimes used for spacecraft generators and terrestrial navigation beacons, as well as neutron detection equipment. <ref>http://www.chemicool.com/elements/neptunium.html</ref>
