Exposure pathway
| Toxic Substances Glossary |
- The route a substance takes from its source (where it began) to its end point (where it ends), and how people can come into contact with (or get exposed to) it. an exposure pathway has five parts: a source of contamination (such as an abandoned business); an environmental media and transport mechanism (such as movement through groundwater); a point of exposure (such as a private well); a route of exposure (eating, drinking, breathing, or touching), and a receptor population (people potentially or actually exposed). when all five parts are present, the exposure pathway is termed a completed exposure pathway.
- The route a substance takes from where it began (source) to its end point.

Exposure, английский
- Exposure of a shot depends on the amount of light entering the lens. this can usually be controlled on your digital camcorder
- Aspect
- Sensitivity to a source of risk
- Экспозиция; воздействие
- Выдержка
- Contact with a substance by swallowing, breathing, or touching the skin or eyes. exposure may be short-term [acute exposure], of intermediate duration, or long-term [chronic exposure].
- The amount of light that reaches the image sensor and is controlled by a combination of the lens aperture and shutter speed.
- The result of light that reaches any recording surface through the combination of time (shutter speed) and quantity (lens diaphragm size).
- Exposure is the phenomenon of light striking the surface of film or a digital imaging sensor. the exposure is determined by the volume of light passing through the lens aperture (f/stop) combined with the duration of the exposure (shutter speed). for more on this subject, see the explora article, “understanding aperture.”
- The amount of light that enters the lens and strikes the film or sensor. exposures are broken down into aperture, which is the diameter of the opening of the lens, and shutter speed, which is the amount of time the light strikes the film. thus, exposure is a combination of the intensity and duration of light.
- The total amount of light reaching the digital sensor. it is controlled by setting the aperture, shutter speed and iso. discover how these 3 elements work together in our article on the exposure triangle.
- Amount of light that hits the image sensor of film controlled by the shutter speed and aperture.

Exposure (rt), английский
The product of the x-ray intensity as measured by filament current in milliamperes and time in seconds or minutes for x-rays, or the product of source strength in curies and time in seconds or minutes for gamma rays. the exposure factor determines the degree of film blackening as long as the reciprocity law is valid. see reciprocity law and reciprocity law failure.

- Lighten or darken the image by overriding the exposure system. also known as ev compensation.
- Adding to or subtracting from the “correct” exposure time indicated by the camera`s light meter, which results in a final exposure that is either lighter or darker than the recommended exposure time. most cameras allow for exposure compensation in 1/2, 1/3, or full-stop increments. note that the “correct” exposure is not necessarily the “best” exposure.
- Modifying the shutter speed or aperture from the camera’s recommended exposure to create a certain effect (over or under exposing)
