The complex syndrome resulting from radiation exposure of more than 200 rads to the skin. The immediate effects can be reddening and swelling of the exposed area (like a severe burn), blisters, ulcers on the skin, hair loss, and severe pain. Very large doses can result in permanent hair loss, scarring, altered skin color, deterioration of the affected body part, and death of the affected tissue (requiring surgery). For more information, see cdc’s fact sheet “acute radiation syndrome” at http://emergency.cdc.gov/radiation/ars.asp.
Industry:Medical devices
The series of decays that certain radioisotopes go through before reaching a stable form. For example, the decay chain that begins with uranium-238 (u-238) ends in lead-206 (pb-206) after forming isotopes, such as uranium-234 (u-234), thorium-230 (th-230), radium-226 (ra-226), and radon-222 (rn-222).
Industry:Medical devices
The fraction of a number of atoms of a radionuclide that disintegrates in a unit of time. The decay constant is inversely proportional to the radioactive half-life.
Industry:Medical devices
The isotopes or elements formed and the particles and high-energy electromagnetic radiation emitted by the nuclei of radionuclides during radioactive decay. Also known as "decay chain products" or "progeny" (the isotopes and elements). A decay product may be either radioactive or stable.
Industry:Medical devices
Disintegration of the nucleus of an unstable atom by the release of radiation.
Industry:Medical devices
The reduction or removal of radioactive contamination from a structure, object, or person.
Industry:Medical devices
Removal of radioactive isotopes from the body using specific drugs called "decorporation agents." (list of countermeasures for treatment)
Industry:Medical devices
Uranium containing less than 0.7% uranium-235, the amount found in natural uranium. See also enriched uranium.
Industry:Medical devices
The activity of a radionuclide per unit area of ground. Reported as becquerels per square meter or curies per square meter.
Industry:Medical devices
A device that is sensitive to radiation and can produce a response signal suitable for measurement or analysis. A radiation detection instrument.
