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

It's an alpha av A VESTERLUND · 2016 — Neutron sources are constructed in a way that the alpha particle from an alpha-emitting radionuclide such as 241Am or 210Po reacts with a low-Z element, commonly beryllium, and a neutron is emitted from the low-Z element nucleus.
