Neutron radiation

Just wanna see if I got this.

When a neutron comes into contact with a nucleus of an atom, two things (that I know of) can happen. One is that the nucleus can absorb the neutron, this typically happens in lighter atoms due to the stronger force over the smaller nucleus being able to withstand the impact and not break apart (this part I made up myself, because I think it may be true), and the nucleus absorbs the kinetic energy of the neutron. This can cause the nucleus to become unstable, due to the energy of the neutron being transferred to the nucles. This typically results in beta decay. If the nucleus is much larger, it may break apart completely, or undergo fission

There are more possibilities. The most common is elastic scattering (bouncing). Others include simple absorption (H1 becomes H2) and also other decay processes besides beta.
