Einsteinium, named after the renowned Albert Einstein, is a silver-coloured, radioactive metal that was first discovered among the debris from a hydrogen bomb test.

Einsteinium is rare, since it is produced synthetically in very small amounts by plutonium fusion reactions in nuclear reactors. Only a few compounds of einsteinium have been discovered, none of which has commercial applications. Einsteinium has no biological role, but if it were produced in large amounts, this element could pose a radiation threat.
