Separation from berkelium is important, because the most common einsteinium isotope produced in nuclear reactors, 253 Es, decays with a half-life of only 20 days to 249 Bk, which is fast on the timescale of most experiments.insteinium is the element with the highest atomic number which has been observed in macroscopic quantities in its pure form, and this was the common short-lived isotope einsteinium-253.
