Ultraviolet radiation
|
- Ultraviolet radiation (uv) is one form of radiant energy coming from the sun. the sun emits a range of energy known as the electromagnetic spectrum. the various forms of energy, or radiation, are classified according to wavelength (measured in nanometres (nm) where one nm is a millionth of a millimetre).
- Sunlight rays or short wave radiation from sources such as welding, lasers, or tanning lamps. uv light can damage the eyes and lead to snow blindness, cataracts and degenerative diseases of the eye.
- Electromagnetic radiation at wavelengths immediately below the visible spectrum, i.e., within the wavelength range 10 to 380 nm. may be classified as: far ultraviolet, 10 to 280 nm; middle ultraviolet, 280 to 315 nm; near ultraviolet, 315 to 380 nm. also may be classified as: ozone-producing, 180 to 220 nm; germicidal, 220 to 300 nm; erythemal, 280 to 320 nm; black light, 320 to 400 nm. in either method of classification, there are no sharp demarcations between the wavelength bands.
- Short invisible rays of ultraviolet light. abbr uvr
- Electromagnetic radiation with wavelengths between 40 and 400 nm. see also irradiance and uv-a.

Ультрафиолетовое излучение, русский
- , не видимое глазом электромагнитное излучение в пределах длин волн ??400-10 нм. различают ближнее ультрафиолетовое излучение (400-200 нм) и дальнее, или вакуумное (200-10 нм). с уменьшением ? коэффициент поглощения ультрафиолетового излучения большинства прозрачных тел растет, и при ?<105 нм прозрачных тел практически нет, в то время как коэффициент отражения материалов падает. источники ультрафиолетового излучения - высокотемпературная плазма, ускоренные электроны, некоторые лазеры, солнце, звезды и др.; приемники - фотоматериалы, различные детекторы ионизирующих излучений. биологическое действие ультрафиолетового излучения обусловлено химическими изменениями поглощающих их молекул живых клеток, главным образом молекул нуклеиновых кислот (днк и рнк) и белков, и выражается в нарушениях деления, возникновении мутаций и в гибели клеток. малые дозы ультрафиолетового излучения оказывают благотворное действие на человека и животных.

- Waves of energy which are given off by some substances, especially radioactive substances comment: prolonged exposure to many types of radiation can be harmful. nuclear radiation is the most obvious, but exposure to x-rays, either as a patient being treated or as a radiographer, can cause radiation sickness. first symptoms of the sickness are diarrhoea and vomiting, but radiation exposure can also be followed by skin burns and loss of hair. massive exposure to radiation can kill quickly, and any person exposed to radiation is more likely to develop certain types of cancer than other members of the population.

- The process of assigning a set of records from a database (observations in a dataset) into (usually) one of ``small" number of pre-specified disjoint categories. related techniques include regression, which predicts a range of values and clustering, which (typically) allows the categories to form themselves. the classification can be "fuzzy" in several senses of the word. in usual sense, the classification technique can allow a single record to belong to multiple (disjoint) categories with a probability (estimated) of being in each class. the categories can also overlap when they are developed either through a hierarchical model or through an agglomerative technique. finally, the classification can be fuzzy in the sense of using "fuzzy logic" techniques. see also: clustering, fuzzy logic, regression. classification and regression trees (cart) classification and regression trees (cart) is a particular form of decision tree used in data mining and statistics.
