A small atomic particle possessing no electrical charge, typically found within an atom's nucleus. Neutrons are, as the name implies, neutral in their charge. That is, they have neither a positive nor a negative charge. A neutron has about the same mass as a proton. See also alpha particle, beta particles, gamma rays, nucleon, x-ray.
Industry:Medical devices
Radiation that has lower energy levels and longer wavelengths than ionising radiation. It is not strong enough to affect the structure of atoms it contacts but is strong enough to heat tissue and can cause harmful biological effects. Examples include radio waves, microwaves, visible light, and infrared from a heat lamp.
Industry:Medical devices
An effect that can be related directly to the radiation dose received. The effect is more severe with a higher dose. It typically has a threshold, below which the effect will not occur. It is sometimes called deterministic effect. For example, a skin burn from radiation is a non-stochastic effect that worsens as the radiation dose increases. See also stochastic effect.
Industry:Medical devices
The heat energy produced by the process of nuclear fission within a nuclear reactor or by radioactive decay.
Industry:Medical devices
The steps involved in supplying fuel for nuclear power plants. It can include mining, milling, isotopic enrichment, fabrication of fuel elements, use in reactors, chemical reprocessing to recover the fissile material remaining in the spent fuel, re-enrichment of the fuel material refabrication into new fuel elements, and waste disposal.
