Gamma rays
| Глоссарий по ядерной энергетике |
- Gamma rays are a type of high energy electromagnetic electromagnetic spectrum in the form of photons which have no mass. in radioactive decay they originate from changes in the structure and energy levels of the atomic nucleus , or, through electron-posit
- The electromagnetic radiation of high frequency or short wavelength emitted by the nucleus of an atom during a nuclear reaction. gamma rays are undeflected by electric or magnetic fields. they are identified in nature and properties to x-rays of the same wavelength, and differ only in their manner of production.
- High energy, short wavelength electromagnetic radiation emitted by the nucleus of a radioactive isotope. energies of gamma rays are usually between 0.01 and 10 mev. x-rays also occur in this energy range but are of nonnuclear origin.

Gamma, английский
- Гамма
- Коэффициент “гамма”. показатель скорости изменения дельты в результате незначительных колебаний цены базовых акций. гамма принимает максимальное значение, когда цена лежащих в основе опциона акций приближается к цене страйк, и стремится к нулю, своему мин
- A numerical value, or the degree of contrast in a television picture, which is the exponent of that power law which is used to approximate the curve of output magnitude versus input magnitude over the region of interest.
- A correction of the linear response of a camera in order to compensate for the monitor
- Correction law introduced in the camera output signal to compensate for the non-linearity of the crt (cathode ray tube) in video monitors. a typical gamma value is 0.45, which results in the brightness component of the crt picture appearing to be linear.
- A measure of the amount of contrast found in an image according to the properties of a gradation curve. high contrast has high gamma and low contrast low gamma.
- A correction of the linear response of a camera in order to compensate for the monitor phosphor screen nonlinear response. it is measured with the exponential value of the curve describing the non-linearity. a typical monochrome monitor’s gamma is 2.2, and a camera needs to be set to the inverse value of 2.2 (which is 0.45) for the overall system to respond linearly (i.e., unity).
- The brightness curve of the color spectrum as displayed (or reproduced) on a computer monitor, a printer or scanner.
- Measure of the amount of contrast in an image according to the properties of a gradation curve. high contrast = high gamma and low = low.
