The fragment products are radioactive nuclei; they emit b particles in
succession to achieve stable end products The energy released (the Q value ) in the fission reaction of nuclei like
uranium is of the order of 200 MeV per fissioning nucleus This is
estimated as follows:
Let us take a nucleus with A = 240 breaking into two fragments each
of A = 120
