|---|---|---|---|
| 설명 | 전자총에서 나오는 속도가 거의 균일한 전자의 연속적 흐름. X선과 마찬가지로 분자나 결정격자에 의해 전자빔의 간섭, 회절 효과를 관측할 수 있어서 분자의 구조를 알아내는 데 사용을 할 수가 있다. 그리고 물체에의 전자의 조사에 이용되기도 하는데, 악성종양에 대한 전자선 요법으로서는 라듐 B 또는 메소토륨같은 방사성 물질을 환부 가까이 위치시켜서 직접 전자선을 투여하여 악성 종양을 치료하는 방법이 있다. |

| attenuation | <radiobiology> Process by which a beam of radiation is reduced in intensity when passing through material - combination of absorption and scattering processes, leading to a decrease in flux density of beam when projected through matter. (16 Dec 1997) |
| attenuation coefficient | 1. <radiobiology> Compton: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing as a result of Compton effect interactions. 2. Linear: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing due to all absorption and scattering processes. 3. Pair Production: That fractional decrease in the intensity of a beam of ionising radiation due to pair production in a medium through which it passes. 4. Photoelectric Effect: That fractional decrease in the intensity of a beam of ionising radiation due to photoelectric effect in a medium through which it passes. (16 Dec 1997) |
| attenuation compensation | In ultrasonography, an increase in receiver gain with time to compensate for loss in echo amplitude with depth, usually due to attenuation. Synonym: attenuation compensation, depth compensation, time compensation gain, time-compensated gain, time-varied gain control, time-varied gain. (05 Mar 2000) |
| attenuation factor | <radiobiology> A measure of the opacity of a layer of material for radiation transversing it, the ratio of the incident intensity to the transmitted intensity. It is equal to Io/I, where Io and I are the intensities of the incident and emergent radiation, respectively. In the usual sense of exponential absorption (I = Ioe- m x), the attenuation factor is e- m x, where x is the thickness of the material and m is the absorption coefficient. (16 Dec 1997) |
| mass attenuation coefficient | <physics> The mass attenuation coefficient, u/p, of a material for uncharged ionising particles is the quotient of DN/N by pdl, where DN/N is the fraction of particles that experience interactions in traversing a distance dl in a material of density p. (16 Dec 1997) |

| Balkan beam | An overhead frame, supported on uprights attached to the bedposts or to a separate stand, from which a splinted limb is slung in the treatment of fracture or joint disease. Synonym: Balkan beam, Balkan splint. (05 Mar 2000) |
| beam | <radiobiology> Stream of particles or electromagnetic radiation travelling in a single direction. (09 Oct 1997) |
| beam dump | <radiobiology> A mass of shielding material which absorbs the energy of a beam of particles or electromagnetic radiation. (09 Oct 1997) |
| beam-plasma reaction | <radiobiology> Fusion reaction which occurs from the collision of a fast beam ion with a thermal plasma ion. (09 Oct 1997) |
| beam splitter | <radiobiology> Optical device for dividing a beam of electromagnetic radiation into two or more separate beams. (09 Oct 1997) |
| beam tree | <botany> A tree (Pyrus aria) related to the apple. Origin: AS. Beam a tree. See: Beam. Source: Websters Dictionary (01 Mar 1998) |
| beam-wall reaction | <radiobiology> Fusion reaction which occurs from the collision of a fast beam ion with an ion embedded in or adsorbed onto the reactor wall. (09 Oct 1997) |
| cantilever beam | In dentistry, a beam that is supported by only one fixed support at only one of its ends. (05 Mar 2000) |
