Gamma rays from antimony-124 split beryllium-9 into two alpha particles and a neutron with an average kinetic energy of 24keV, intermediate neutrons. The other products are two alpha particles.
Radiation emitted by antimony-124 causes the disintegration of beryllium-9, resulting in the emission of two alpha particles and a neutron with an average energy of 24keV, along with some intermediate neutrons. Two more alpha particles are also produced.
