96Cm Curium

Year Discovered


Discovered By

Albert Ghiorso, Ralph James and Glenn Seaborg of the USA

Biological Rating

Not necessary for life.


Named after Pierre and Marie Curie, curium is a silvery, radioactive metal. It is a chemically active metal, reacting with air, water and acids but not bases. It has never been found naturally, but several kilograms are produced each year. Currently, curium is only used in research, but it has potential as a portable heat and power source. The spectrometer carried by the robotic Sojourner rover on Mars used curium as a source of alpha particles. The most stable isotope of curium has a half-life of 15,600,000 years.

Biological Benefits
