Discovery Information
Who: G.T.Seaborg , R.A.James, A. Ghiorso
When: 1944
Where: United States
Name Origin
In honor of Pierre and Marie Curie.
Sources
Made by bombarding plutonium with helium ions . So radioactive it glows in the dark.
Uses
As curium is only available in extremely limited quanities, it has few uses, however, it was used on a Mars mission as an alpha particle source for the Alpha Proton X-Ray Spectrometer.
Notes
The isotope curium-248 has been synthesized only in milligram quantities, but curium-242 and curium-244 are made in multigram amounts, which allows for the determination of some of the element's properties.
Curium bio-accumulates in bone tissue where its radiation destroys bone marrow and thus stops red blood cell creation.
