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 radiation. This will result in a chain reaction of nuclear radiation, which makes radiation dangerous and harmful over great areas of space

- Cerenkov radiation
- Light emitted in the Cerenkov effect
- Cherenkov radiation
- Variant of Cerenkov radiation. Light produced by charged particles when they pass through an optically transparent medium at speeds greater than the speed of light in that medium. For example, when electrons from a nuclear reactor travel through shielding water, they do so at a speed greater than that of light through water and they displace some electrons from the atoms in their path. This causes emission of electromagnetic radiation that appears as a weak bluish-white glow. The phenomenon is named for Pavel A. Cherenkov (1904-1990), who discovered it; he shared a 1958 Nobel Prize with Igor Y. Tamm (1895-1971) and Ilya M. Frank (1908-1990), who interpreted the effect
- Hawking radiation
- A form of radiation believed to emanate from black holes, arising from the creation of pairs of subatomic particles in the space adjacent to the black hole, with one particle falling into the black hole and the other radiating away. The energy lost to such radiated particles is believed to cause the eventual disappearance of the black hole. Radiation theoretically emitted from just outside the event horizon of a black hole. Stephen W. Hawking proposed in 1974 that subatomic particle pairs (photons, neutrinos, and some massive particles) arising naturally near the event horizon may result in one particle's escaping the vicinity of the black hole while the other particle, of negative energy, disappears into it. The flow of particles of negative energy into the black hole reduces its mass until it disappears completely in a final burst of radiation
- High-speed Anti-Radiation Missile
- HARM, type of missile that zeroes in on sources of radar radiation
- Van Allen radiation belts
- Two doughnut-shaped zones of highly energetic charged particles (see electric charge) trapped at high altitudes in Earth's magnetic field. Named for James A. Van Allen (b. 1914), who discovered them in 1958, they are most intense over the Equator and effectively absent above the poles. The two zones merge gradually, with the flux of charged particles showing two regions of maximum density. The inner one, mostly protons thought to be produced by primary cosmic rays striking the atmosphere, is centred about 3,700 mi (6,000 km) above Earth's surface. The outer region includes some helium ions from the solar wind and is centred about 12,500 mi (20,000 km) above Earth's surface. Intense solar activity (see solar cycle) causes disruptions of the belts, linked in turn with such phenomena as auroras and magnetic storms
