Neutron radiation

Neutron radiation is nuclear radiation, consisting of a neutron fluxes. The main source of neutrons of different energies is a nuclear reactor (see nuclear Reactors). At interaction with tissues neutron radiation produces ionization environment. Since neutrons carry no electrical charge (see Atom), ionization is due to secondary nuclear particles (protons and others)formed as a result of nuclear reactions. Depending on the energy of the neutrons are divided into slow with energies up to 100 Kev and fast with energies up to 10 MeV. Slow neutrons easily captured by nuclei of atoms environment, the formation of strongly ionizing secondary particles. This property use slow neutrons in neutron capture therapy (see Neutron therapy). Due to the absence of electric charge neutrons are in substance considerable distances. In this regard, under neutron irradiation of large objects is achieved by a high degree of uniformity dose field. Slow and fast neutrons may cause fission of such heavy elements such as plutonium (see), thorium (see), uranium (see). Such fission reactions are widely used in various industries.
