A device in which a controlled, self-sustaining nuclear chain reaction can be maintained with the use of cooling to remove generated heat.
Industry:Medical devices
Unit pertaining to the disintegrations per gram of a radioisotope (mettler fa jr, upton ac: medical effects of ionizing radiation, 3rd ed. Philadelphia, pa: saunders elsevier, 2008, page 554)
Industry:Medical devices
Radioisotopes that give doctors the ability to "look" inside the body and observe soft tissues and organs, in a manner similar to the way x-rays provide images of bones. A radioactive tracer is chemically attached to a compound that will concentrate naturally in an organ or tissue so that an image can be taken.
Industry:Medical devices
The nucleus of an atom in which the forces among its particles are balanced. See also unstable nucleus.
Industry:Medical devices
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 characterized 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 vaporize 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).
