But, there are very few actual uses for einsteinium besides scientific research. One isotope is used in the calibration process of the chemical analysis spectrometer in a lunar probe.
This isotope was produced through the absorption of 6 neutrons by a nucleus of uranium-238, which was followed by beta decay. Einsteinium is one of the trans-uranic elements, which are elements with an atomic number higher than 92 (all of them are radioactive). It was aptly named after Albert Einstein. The most common isotope of Es is Es-253, which is generated in several high-power nuclear reactors, albeit in minute quantities.
