In this kind of RTG, the alpha decay from the radioisotope is also used in alpha-neutron reactions with a suitable element such as beryllium. This way a long-lived neutron source is produced. Because the system is working with a criticality close to but less than 1, i.e. K eff < 1, a subcritical multiplication is achieved which increases the neutron background and produces energy from fission 1-800-654-9845.
