The Element Curium - Basic Physical and Historical Information ...

Curium In the Summer of 1944 G.T. Seaborg, R. A. James and A. Ghiorso, working at the Manhattan Project, performed a careful chemical fractionation on a sample of plutonium which had been irradiated with 32 MeV helium ions at the University of California. A new radioactive isotope was found, which emitted 4.7 MeV alpha particles and was chemically separable from neptunium and plutonium. Both ...

Discovered : 1944 by Glenn Seaborg and co-workers Isolated in Berkeley, California, USA Origin : The element is named after Pierre and Marie Curie. Description : A radioactive metal made in nuclear reactors from plutonium. Only a few grammes are produced each year. Image : Curium is used in satellite technology. ...
