About Curium

Curium is a silvery radioactive metal which was obtained for the first time by a group of American scientists in the middle of the 20th century and given the name after Maria and Pierre Curie. It is one of the actinides which are toxic and very dangerous to the living organisms on our planet. Though micro amounts of pure curium can be detected in uranium ores, this element is mostly produced in nuclear reactors and only in the amounts of a few grams a year. The main application of this chemical element is providing energy to various space missions.
