In gamma radiation no particle is released, just a “packet” of energy.. Photon- “packet” of energy.. When an atom has too much energy, it is . excited. , it’s electrons are in higher energy levels.. Enormous Energies. Nuclear Fission. Take a large atom and impact the nucleus with a particle. . Split the atom releasing high energy, more high energy neutrons, and two daughter nuclides.. Fission occurs only rarely in nature. Alpha decay is much more common..
