The second product produced in this chain is actinium-228. Which of the following processes could lead to this product starting with thorium-232?(a) Alpha decay followed by beta emission(b) Beta emission followed by electron capture(c) Positron emission followed by alpha decay(d) Electron One example of a radioactive decay series is the sequence of decays that starts with Thorium-232 which ends up as Lead-208.
