| environmental exposure | The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals. (12 Dec 1998) |
| exposure | <radiobiology> A quantitative measure of x or gamma radiation at a certain place, based on its ability to produce ionisation in air. The former special unit of exposure was the roentgen (R). 1R = 2.58 x 10-4 C/kg. In the international system (SI unit), the special unit is coulomb per kilogram. (Exposure also is frequently used as a synonym for irradiation). (16 Dec 1997) |
| exposure dose | The radiation dose, expressed in roentgens, delivered at a point in free air. Synonym: air dose. (05 Mar 2000) |
| exposure keratitis | Inflammation of the cornea resulting from irritation caused by inability to close the eyelids. Synonym: lagophthalmic keratitis. (05 Mar 2000) |
| exposure odds ratio | <epidemiology> See Odds ratio. (05 Dec 1998) |
| kilogram-meter | <unit> A measure of energy or work done, being the amount expended in raising one kilogram through the height of one meter, in the latitude of Paris. Source: Websters Dictionary (01 Mar 1998) |
