3. (20 points) The radioisotope 224Ra decays by alpha emission via two paths to the ground state of its daughter: 94% probability of alpha decay directly to the daughter ground state; 5% probability of alpha decay to an excited state before emitting a 0.241 MeV photon in an isomeric transition to reach the ground state of the daughter. Write the reaction equation for the alpha decay of 224Ra (4 points) Do not type this response into Canvas. Only include on scratch paper. Calculate the Q-value (in MeV) of this reaction. (4 points) What are the energies (in MeV) of the two associated alpha particles from the two decay modes? (6 points) Sketch the decay scheme for the decay of 224Ra with the associated probabilities, energies, and emissions for the alpha decays and any accompanying photons clearly labeled (6 points).
