Množina: gammas

The 3rd letter of the Greek alphabet.
Third letter (G, g) of Greek alphabet

Množina: gamma globulins

Any of a group of globulins, including most antibodies, concerned with immunity.A protein fraction of human blood plasma containing numerous antibodies; SYN. human gamma globulin.

Množina: gamma radiations

Electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength; SYN. gamma ray.
Very high-frequency electromagnetic radiation, similar in nature to X-rays but of shorter wavelength, emitted by the nuclei of radioactive substances during decay or by the interactions of high-energy electrons with matter. Cosmic gamma rays have been identified as coming from pulsars, radio galaxies, and quasars, although they cannot penetrate the Earth's atmosphere.
Gamma rays are stopped only by direct collision with an atom and are therefore very penetrating; they can, however, be stopped by about 4 cm/1.5 in of lead or by a very thick concrete shield. They are less ionizing in their effect than alpha and beta particles, but are dangerous nevertheless because they can penetrate deeply into body tissues such as bone marrow. They are not deflected by either magnetic or electric fields.
Gamma radiation is used to kill bacteria and other microorganisms, sterilize medical devices, and change the molecular structure of plastics to modify their properties (for example, to improve their resistance to heat and abrasion).

Množina: gamma rays

Short-wavelength electromagnetic radiation, similar to x-rays but of nuclear origin, with a range of wavelength from about 10-14 10-10 m.
Kind of radioactive ray resembling X-rays.
