This scarcity stems from the fact that astatine is primarily found as a decay product of heavier elements, such as uranium and thorium. It is not mined directly but instead forms through radioactive decay processes.

Its radioactive nature means that astatine has a short half-life, with its most stable isotope, astatine-210, having a half-life of just 8.1 hours. This characteristic poses challenges for scientists studying its properties and applications.
