238Pu, which decays by the emission of an alpha-particle, has been used as a thermal power source. (a) What is the daughter nuclide the results from the alpha-decay of 238Pu? (b) What is the Q-value for the radioactive decay in MeV? [ Ans. 5.59 MeV ] (c) What is the energy recoverable as heat per decay in MeV? Provide two answers, one assuming all of the energy produced is dissipated as heat, and one assuming only the kinetic energy of the alpha particle is useful.
