Neutron Radiation - Wikipedia, The Free Encyclopedia
Neutron radiation is a kind of ionizing radiation which consists of free neutrons. A result of nuclear fission or nuclear fusion, it consists of the release of free neutrons from atoms, and these free neutrons react with nuclei of other atoms to form new isotopes, which, in turn, may produce ...

Neutron - Wikipedia, The Free Encyclopedia
The neutron is a subatomic particle, symbol n or n 0, with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons, each with mass approximately one atomic mass unit, constitute the nucleus of an atom, and they are collectively referred to as nucleons. [5] ... Read Article
