Question

3. When bismuth-210 decays, it can do so either via alpha decay or via negative beta decay. [Note: you
may assume that the recoil energy of the daughter nucleus is negligible and may be ignored for both
types of decay.]
a) Write the nuclear decay equations for both the beta decay and the alpha decay.
b) Compute the kinetic energy of the emitted alpha particle in the alpha decay in units of MeV.
