Biological Rating

Not necessary for life.


Named after the Italian-American physicist Enrico Fermi, fermium is a highly radioactive metal. It was discovered in the radioactive fallout of a 1952 atomic bomb test. It has never been found naturally and only a few micrograms are produced each year. Its chemistry and appearance are not known with any certainty but should be similar to the other actinides. Fermium is too rare to have any commercial or industrial application. The most stable isotope of fermium has a half-life of 100 days.

Biological Benefits
