Description: Silver … WebAstatine-211 is not only an alpha emitter, it has also got a very short half life and the fact that it decays to a stable non-radioactive isotope of lead means that the radiation dose is quite brief. It even has a secondary decay pathway that creates a few x-rays which doctors could use to track exactly where the isotope is in the body.
