Bismuth206
Bismuth-206 is a radioactive isotope of bismuth. It has a half-life of 6.45 hours. Bismuth-206 decays primarily by positron emission and electron capture to form polonium-206. It also undergoes alpha decay to thallium-202. The decay chain of bismuth-206 is part of the broader decay pathways of heavier elements.
This isotope is not found naturally on Earth and is produced artificially through nuclear reactions. It can
