WebOne example of a radioactive decay series is the sequence of decays that starts with Thorium-232 which ends up as Lead-208. What we mean is that Thorium-232 decays into Radium-228 plus an alpha particle. That isotope of Radium subsequently decays into Actinium-228 via beta decay, and so on until Lead-208 is the final end product. Web15.
