摘要

描述
English: Diagram of the thorium decay chain from lead-212 to lead-208. Each parent nuclide spontaneously decays into a daughter nuclide (the decay product) via an α decay or a β decay. Note that bismuth-212 can either decay into polonium-212 or thallium-208. The final decay product, lead-208, is stable and can no longer undergo spontaneous radioactive decay.
English: This image was created as part of the Philip Greenspun illustration project.
