- Einsteinium is a synthetic element and a part of the periodic table with atomic number 99.
- Einsteinium which is transuranium was discovered during the analysis of nuclear products recovered from debris following a thermonuclear explosion (Weapon test device, “Mike”, November 1952) in the Pacific Ocean. Through initial investigations, fermium and another element were discovered.
- The second element was named in honor of Albert Einstein, and given the symbol, it is produced through a chain of nuclear reactions that involves bombarding each isotope then allowing isotope beta decay.
- Only tiny amounts of einsteinium have ever been produced, it is mainly used in scientific studies. Radioactive decay can be discovered through Einsteinium.
- It is among the heaviest element on which bulk studies can be performed.
- It has a few medical uses but they are not commercial.
- It is used majorly to study radiation damage, targeted radiation medical treatments and for accelerated aging.
