PHONETICS

IDENTIFICATION

Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion. Its most common isotope einsteinium-253 has a half-life of 20.47 days and is produced artificially from decay of californium-253 in a few dedicated high-power nuclear reactors with a total yield on the order of one milligram per year. The reactor synthesis is followed by a complex procedure of separating einsteinium-253 from other actinides and products of their decay. There are currently almost no practical applications for it outside of basic scientific research.
