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.
Industry:Medical devices
A nonmetallic solid element. There are both radioactive and non-radioactive isotopes of iodine. Radioactive isotopes of iodine are widely used in medical applications. Radioactive iodine is a fission product and is the largest contributor to people’s radiation dose after an accident at a nuclear reactor.
Industry:Medical devices
An atom that has fewer or more electrons than it has protons, causing it to have an electrical charge and, therefore, be chemically reactive.
