| Applications | A radioactive element discovered in 1952 in the debris from a nuclear detonation, Known isotopes include Es-243 to Es-256. About 3 mg of einsteinium has been produced at Oak Ridge National Laboratories by irradiating kilogram quantities of Pu-239 for several years to produce Pu-242, fabricating the Pu-242 into pellets, and loading the pellets into target rods for16 months of irradiation. The 14 isotopes have short half-lives. The longest half-life is 275 days (Es-254) [http://periodic.lanl.gov/elements/99.html] |

Packaging is agreed per order, from lab-scale packs to bulk, and confirmed with each order rather than fixed on the page. A Certificate of Analysis (COA) ships with every batch and MSDS is available; where the end use carries a regulatory limit (food contact, pharmaceutical or cosmetic), state the standard at enquiry and the grade is set against it.
