A Neutron source is a device that emits neutrons. There is a wide variety of different sources, ranging from hand-held radioactive sources to research reactors and spallation sources. Depending upon neutron energy, neutron flux, size of the source, costs, and government regulations, these devices find use in a diverse array of applications in areas of physics, engineering, medicine, nuclear weapons, petroleum exploration, biology, chemistry, nuclear power and other industries.
