    Who / Where / When / How

    • Discoverer: G.T.Seaborg, R.A.James, A.Ghiorso
    • Discovery Location: Berkeley California United States
    • Discovery Year: 1944
    • Name Origin:
      In honor of Pierre and Marie Curie.
    • Abundance of Curium:
      • Earth's Crust/p.p.m.: N/A
      • Seawater/p.p.m.: nil
      • Atmosphere/p.p.m.: N/A
      • Sun (Relative to H=1E12): N/A
    • Sources of Curium:
      Made by bombarding plutonium with helium ions. So radioactive it glows in the dark. Several kilograms of curium are produced each year.
    • Uses of Curium:
      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. Curium is a potential isotope power source as it releases three watts of heat energy per gram gram.
    • Additional Notes:
      Individuals will never normally encounter curium as it does not occur in nature and is only produced in limited quantities.
