Radioactive isotope
|
- Isotope radioactif
- An isotope which sends out radiation, used in radiotherapy and scanning

Isotope, английский
- An isotope represents atoms of the same element that have the same number of protons but a different number of neutrons . they therefore have different atomic masses but the same chemical properties. a radio-isotope is an isotope which is radioactive .
- A form of a chemical element which has the same chemical properties as other forms but a different atomic mass
Isotope (rt), английский
One of several nuclides having the same number of protons in their nuclei, and hence belonging to the same element, but differing in the number of neutrons, and therefore in mass number. small quantitative differences in chemical properties exist between elements and isotopes. isotopes may or may not be unstable. unstable isotopes undergo transitions to other isotopes or elements with a loss of energy. such energy is usually given off in the form of electromagnetic or particle radiation. isotopes are used as source of radiation for radiography.

Isotopes, английский
Изотопы. нуклиды, имеющие один и тот же атомный номер, но различное массовое число (мос, 5). (атомный номер равен числу протонов, массовое число.— это число нуклонов, т. е. число протонов и нейтронов). все изотопы данного элемента имеют идентичные химические свойства, но различную атомную массу; одни могут быть радиоактивными, другие — нет. 6—1113 jet, overfire — верховая струя. струя воздуха или пара, подаваемая для усиления турбулентности над топливным слоем в печи и тем самым для снижения образования дыма. к
Radioactive, английский
- Radioactive can generally describe the property of a substance (or more accurately atomic nuclei) which are unstable and spontaneously decay (disintegrate) with the release of energy, the energy being either electromagnetic radiation , particulate or both
- Радиоактивный
- Generally, the property possessed by certain elements, such as uranium minerals, of spontaneously emitting alpha, teta, and/or gamma rays by the disintegration of the nuclei of their atoms.
- Atoms that are energetically unstable and decay to a stable condition by emitting radiation are said to be radioactive.

Átomo radioactivo
Radioactive contamination, английский
Deposition of any radioactive material in any place where it is not desired, particularly where it may be harmful.
Radioactive decay, английский
- Radioactive decay describes the process where by radioactive substances decay spontaneously with the release of energy in the form of electromagnetic radiation or particulate radiation. the rate of radioactive decay will depend on the half-life .
- The spontaneous disintegration of the atoms of certain nuclides into other nuclides, which may be stable or undergo further decay until a stable nuclide is created.
Radioactive decay (rt), английский
The spontaneous nuclear disintegration of a material. it occurs on an atomic scale by the loss of subatomic particles (i.e., protons, neutrons, electrons, etc.). see half-life.
Radioactive decay pattern, английский
Тип радиоактивного распада (напр., совокупности элементов, содержащихся в выгруженном из энергетического реактора облученном горючем)

Radioactive fallout, английский
1. выпадение радиоактивных осадков; 2. радиоактивные осадки. (см. fallout, radioactive.)
Radioactive family, английский
Radiotherapy, английский
The treatment of diseases by exposing the affected part to radioactive rays such as x-rays or gamma rays comment: many forms of cancer can be treated by directing radiation at the diseased part of the body.

Radiation, английский
- Rayonnement
- Energy transmitted from a heat source to the air around it. radiators actually depend more on convection than radiation.
- Energy radiated in the form of waves or particles; photons.
- Radiation is a general term for energy which radiates out from a source and which can be particulate or part of the electromagnetic spectrum . it is more useful to specify the quality of the radiation, for example ionising radiation or non-ionising radiat
- Излучение; лучеиспускание; радиация
- Радиация, излучение
- Излучение; охлаждаемый излучением
- Systems, incorporated фирма «рэдиейш`н системз инкор- порейтед»
- In the context of optics, electromagnetic energy is released; the process of releasing electromagnetic energy.
- 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.

- Излучение; радиация; лучеиспускание
- Радиация, излучение. в общем смысле — а) испускание или перенос энергии в виде электромагнитных волн или частиц; б) сама энергия, называемая также «лучистая энергия» (вмо). в радиационной физике радиация определяется более конкретно как: 1) электромагнитная или квантовая энергия (например, рентгеновские лучи и гамма-лучи); 2) корпускулярное излучение, состоящее из а) заряженных частиц (например, альфа-частиц, электронов,`протонов, дейтронов) и б) незаряженных частиц (например, нейтронов) (мэк, 2). на приводимой схеме дано примерное расположение спектра электромагнитной энергии с указанием типов радиации, рассмотренных в данном словаре. ю-14 ю"`3 ю-12 к)"11 ю-10 to" длина волны (м) ю"8 ю~7 ю"6. ю"5 1сг4 ю"3 1сг2 ю"1 1 космические рентгеновские- лучи лучи фотоны ультрафиолетовое излучение инфракрасное излучение радар гамма - лучи -минроволны л=3,8*ю~ =7,6*10 ~7 м спектр электромагнитного излучения
- The dissipation of energy from a source into its surroundings by the emission of waves or particles.
- A heat transfer process whereby heat is given off through electromagnetic radiation, usually infrared rays.
- Heat transfer by way of electromagnetic energy.
- The transfer of energy through propagation of electromagnetic waves. see also radiant energy. radiographic testing (rt): use of penetrating radiant energy in the form of x-rays, gamma rays, or neutrons for volumetric nondestructive testing of objects to provide images of the objects’ interiors. also called radiography; radiologic testing.
