Hey there!
Nuclei with a high neutron-to-proton ratio usually undergo a beta emission.
Beta emissions, unlike some other types, is radioactive decay throughout these particles, and can have half lives like other types of exponential (usually) decay. Neutrino, along with <em>beta rays,</em> are coming from, or emitted from the nucleus - hence the name.
Hope this helps!
