The ratio of the amount of a specific substance in a given volume or mass of solution to the mass or volume of solvent.
Industry:Medical devices
An organization whose members represent state radiation protection programs. For more information, see the crcpd web site at http://www.crcpd.org.
Industry:Medical devices
the deposition of unwanted radioactive material on the surfaces of structures, areas, objects, or people where it may be external or internal. (animations of contamination) see also decontamination, incorporation.
Contamination means that radioactive materials in the form of gases, liquids, or solids are released into the environment and contaminate people externally, internally, or both. An external surface of the body, such as the skin, can become contaminated, and if radioactive materials get inside the body through the lungs, gut, or wounds, the contaminant can become deposited internally.
Industry:Medical devices
An area where entry, activities, and exit are controlled to help ensure radiation protection and prevent the spread of contamination.
Industry:Medical devices
Radiation produced in outer space when heavy particles (nuclei of all known natural elements) bombard the earth. See also background radiation, terrestrial radiation.
Industry:Medical devices
The international system (si) unit of electric charge. A coulomb is the quantity of charge passing a cross section of conductor in one second when the current is one ampere.
Industry:Medical devices
A fission process where the neutron production rate equals the neutron loss rate to absorption or leakage. A nuclear reactor is "critical" when it is operating.
Industry:Medical devices
The minimum amount of fissile material that can achieve a self-sustaining nuclear chain reaction.
Industry:Medical devices
The total dose resulting from repeated or continuous exposures of the same portion of the body, or of the whole body, to ionizing radiation. For more information, see “primer on radiation measurement ” from cdc.
Industry:Medical devices
The traditional measure of radioactivity based on the observed decay rate of 1 gram of radium. One curie of radioactive material will have 37 billion disintegrations in 1 second. For more information, see “primer on radiation measurement” from cdc.
