An effect that occurs on a random basis independent of the size of dose. The effect typically has no threshold and is based on probabilities, with the chances of seeing the effect increasing with dose. If it occurs, the severity of a stochastic effect is independent of the dose received. Cancer is a stochastic effect. See also non-stochastic effect, deterministic effect.
Industry:Medical devices
The central part of an atom that contains protons and neutrons. The nucleus is the heaviest part of the atom.
Industry:Medical devices
A silvery, soft metal that rapidly turns yellow in air. Sr-90 is one of the radioactive fission materials created within a nuclear reactor during its operation. Stronium-90 emits beta particles during radioactive decay.
Industry:Medical devices
A general term applicable to all atomic forms of an element. Nuclides are characterised by the number of protons and neutrons in the nucleus, as well as by the amount of energy contained within the atom.
Industry:Medical devices
A nuclear weapon explosion that is close enough to the ground for the radius of the fireball to vaporise surface material. Fallout from a surface burst contains very high levels of radioactivity. See also air burst. For more information, see chapter 2 of cdc’s fallout report (pdf - 32.24 mb).
Industry:Medical devices
P-100 filtering face piece disposable particulate respirators are capable of filtering at least 99.97% of airborne particles measuring ≥0.3 micron in diameter. Filtering face piece respirators designated with a "p" are strongly resistant to oil.
Industry:Medical devices
Waste rock from mining operations that contains concentrations of mineral ore that are too low to make typical extraction methods economical.
Industry:Medical devices
The routes by which people are exposed to radiation or other contaminants. The three basic pathways are inhalation, ingestion, and direct external exposure. See also exposure pathway.
Industry:Medical devices
A “hydrogen bomb.” A device with explosive energy that comes from fusion of small nuclei, as well as fission.
Industry:Medical devices
Radiation that can penetrate the skin and reach internal organs and tissues. Photons (gamma rays and x-rays), neutrons, and protons are penetrating radiations. However, alpha particles and all but extremely high-energy beta particles are not considered penetrating radiation.
