Definition of fast neutron in English: fast neutronnoun A neutron with high kinetic energy, especially one released by nuclear fission and not slowed by any moderator. Example sentencesExamples - LETs in this range are high and cannot be obtained with X rays or fast neutrons.
- The normalizing factor for exposure to alpha particles is 20, for thermal neutrons is two, for fast neutrons is 10, for protons is 10, and for beta particles is one.
- In the fast breeder reactor, the fuel is enriched up to 25 per cent and the reactor can be run on fast neutrons alone.
- Mutation rates after low linear energy transfer radiation, such as X rays, rays, and fast neutrons, have been extensively studied in plants.
- They'd worked with slow neutrons instead of fast neutrons.
