Light contamination
| Глоссарий по тестированию |
- In fluorescent nondestructive testing, unwanted visible light present in darkened test area. sources may include gaps in curtains, leaked visible light from the uv-a source, or fluorescence from the inspector’s clothing.

Contaminate, английский
The admixture or introduction of unde-sired substances to a medium, thereby reducing the value of the medium or making it unfit for its in¬tended use. example: cave material from nonore zones admixed with sludge sample from an ore zone.

Contamination, английский
- Usually an undesirable situation where radioactive material in an unsealed source (open source) state is present in the working environment, or otherwise un-contained and not required. contamination can either be loose (easily removed) or fixed. loose con
- Загрязнение; заражение
- The introduction of sewage, wastes, and/or chemicals (or other material) into a potable water supply that render it unfit for its intended purpose. contemporary style an imprecise term applied to any of a number of architectural modes popular from about the 1940s through the 1970s and beyond, sometimes included under the term modern architecture; often characterized by widely overhanging eaves, exposed roof beams, and front-facing gables with heavy piers that support the gables; often, a balcony with an overhanging sunscreen, roof decks, and a patio that may serve as an extension of the living area; another type has a facade and flat roof resembling that of the international style. continuous beam 251
- The action of contaminating something, or the state of being contaminated the contamination resulted from polluted water.
- N лнгв., лит. контаминация (син. blending)
- Инфицирование; контаминация
- The act or process of a substance being diluted or admixed with another material, which may render the original substance unfit for use. see contaminate.
- Undesirable substances (dust, fibers, etc.) in the coating system and powder coating
- Загрязнение. увеличение количества аналита в процессе экстрак-ции в противоположность наблюдаемым обычно потерям, которые оцениваются по выходу.
- Загрязнение. увеличение количества аналита в процессе экстракции в противоположность наблюдаемым обычно потерям, которые оцениваются по выходу.
- Introduction of unwanted microorganisms
Contamination (pt, mt), английский
Any material in the wet suspension other than the liquid vehicle and the magnetic material being used. this could be shop dust, lint, soil from improperly cleaned parts, oil, etc.
Contamination (rt), английский
The presence of unwanted radioactive matter, or the “soiling” of object or materials with “radioactive dirt.”
Contamination class, английский
Класс чистоты гс, га или рабочей жидкости задается стандартами
Contamination control, английский
- A broad subject which applies to all types of material systems (including both biological and engineering). it is concerned with planning, organizing, managing, and implementing all activities required to determine, achieve and maintain a specified contamination level.
- Средства фильтрации, контроля и измерения чистоты рабочей жидкости
Contamination risk, английский
Contamination, pollution, английский
Contaminator, английский
Предприятие и т.п., загрязняющее воду, атмосферу и т.п.
Fluorescent, английский
- Флуоресцирующий; флуоресцентный (о надписи)
- U-lamp a tubular lamp whose bulb has a 180° bend at the center,
- Having the property to produce fluorescence.
- The ability of certain materials to absorb energy and then immediately release that energy in the form of light
Nondestructive, английский
- Неразрушающий
- Неразрушающий (об испытаниях и т.п.)
Fluorescence, английский
- Emission of light of particular wavelength, as a result of absorption of light at shorter wavelength. it is a property of some materials; each material has a specific wavelength of absorption and emission.
- Luminescence arising from irradiation with light
- The emission of visible light from a substance (such as a phosphor) as the result of, and during, the absorption of radiation of shorter wavelengths.
- The sending out of light from a substance which is receiving radiation
- Certain diamonds exhibit colored luminescence (usually blue) when exposed to strong sunlight or ultraviolet light. all you need to know about diamond fluorescence.
- Emission of visible light by a material such as diamond when it is simulated by higher energy x-rays, ultraviolet radiation or other forms of radiation. fluorescence continues only as long as the material is exposed to the radiation. strong or very strong fluorescence may make a diamond appear milky or oily especially in sunlight.
- Fluorescence happens when a diamond is exposed to ultraviolet light, it may emit a soft glow of white-ish, blue-ish or yellowish light. diamond grading reports will most often note whether a diamond has fluorescence, however, is not considered a grading factor, only a characteristic of that particular diamond.
- The property by which some minerals and some organic substances, when exposed to ultra¬violet radiations, emit a light of a color differing from their own, like the blue-white light emitted by scheelite.
- Emission of electromagnetic radiation, usually as visible light, that is caused by the flow of energy into the emitting body. the emission ceases abruptly when the excitation ceases. fly: the short, waste fibers that are released into the air in textile processing operations such as picking, carding, spinning, and weaving.
- The process in which molecules or matter absorb high energy photons and then emit lower energy photons. the difference in energy causes molecular vibrations.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer wavelength). in visual testing, fluorescence is typically a response to ultraviolet radiation.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence in ndt may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed.
- Phenomenon of absorption of electromagnetic radiation and its reemission at a lower energy (longer) visible light wavelength. fluorescence may be a material’s response to ultraviolet or ionizing radiation. the emission ceases as soon as the exciting energy is removed. differs from phosphorescence, which continues to emit after excitation energy is removed. see also spectrofluorometer.
- Luminescent phenomenon exhibited by some substances where higher energy electromagnetic waves are absorbed and reemitted as lower energy waves. the emission ceases as soon as the exciting energy is removed. different from phosphorescence, which will continue to emit after the exciting energy is removed. in magnetic particle testing, pigments coating the magnetic particles are excited by invisible uv-a radiation and emit visible light.
