United States Department of Health and Human Services, Radiation Emergency Medical Management
A scientific field that focuses on protection of humans and the environment from radiation. Health physics uses physics, biology, chemistry, statistics, and electronic instrumentation to help protect individuals from any damaging effects of radiation. For more information, see the health physics society web site at http://www.hps.org/.

A philtre that is at least 99.97% efficient in removing monodisperse particles of 0.3 micrometres in diameter. The equivalent niosh 42 cfr 84 particulate philtres are the n100, r100, and p100 filters. (source: niosh respirator selection logic, 2004. Dhhs(niosh) publication no. 2005-100. And assigned protection factors for the revised respiratory protection standard, 2009. Osha u.s. department of labour publication no. 3352-02 2009.)
Industry:Medical devices
The radioactive material resulting from spent nuclear fuel reprocessing. This can include liquid waste directly produced in reprocessing or any solid material derived from the liquid waste having a sufficient concentration of fission . Other radioactive materials can be designated as high-level waste if they require permanent isolation. This determination is made by the u.s. nuclear regulatory commission on the basis of criteria established in u.s. law. See also low-level waste, transuranic waste.
Industry:Medical devices
Uranium that is enriched to above 20% uranium-235 (u-235). Weapons-grade heu is enriched to above 90% in u-235. (chemical/biological/radiological incident handbook, central intelligence agency)
Industry:Medical devices
Any place where the level of radioactive contamination is considerably greater than the area around it.
Industry:Medical devices
A level of exposure to airborne contaminants likely to cause (1) death; (2) immediate or delayed permanent adverse health effects; or (3) prevent escape from such an environment. Idlh values are considered a maximum level above which only a highly reliable breathing apparatus providing maximum worker protection is permitted. (source: documentation for immediately dangerous to life or health concentrations (idlh), niosh)
Industry:Medical devices
Incorporation refers to the uptake of radioactive materials by body cells, tissues, and target organs such as bone, liver, thyroid, or kidney. In general, radioactive materials are distributed throughout the body based upon their chemical properties. Incorporation cannot occur unless contamination has occurred. Incorporation is also called internal contamination.
Industry:Medical devices
1) the act of swallowing; 2) in the case of radionuclides or chemicals, swallowing radionuclides or chemicals by eating or drinking.
Industry:Medical devices
1) the act of breathing in; 2) in the case of radionuclides or chemicals, breathing in radionuclides or chemicals.
Industry:Medical devices
The relationship that states that electromagnetic radiation intensity is inversely proportional to the square of the distance from a point source.
