(sc) the emission of high-energy photons.
Gamma radiation is electromagnetic radiation of extremely short wavelength. Gamma radiation ranges in energy from about 10-15 to 10-10 J (10 keV to 10 MeV) (wavelength less than about 1 pm). Gamma rays are emitted by excited atomic nuclei during the process of passing to a lower excitation state. Gamma rays are extremely penetrating and are absorbed by dense materials like lead and uranium. Exposure to gamma radiation may be lethal.
A high-energy electromagnetic, ionizing radiation that comes from the nucleus of an atom undergoing radioactive decay. Gamma rays are similar to medical X-rays but are emitted at very specific energies characteristic of their decaying atoms. Gamma rays penetrate body tissues and may damage cells. People exposed to the atomic bombings of Hiroshima and Nagasaki were exposed to gamma radiation. Cesium-137 is a source of gamma radiation.
electromagnetic radiation of extremely short wavelength given off during radioactive decay
Electromagnetic radiation emitted in a nuclear process.
High energy electromagnetic waves, such as those released during radioactive decay of some nuclei. Gamma, the third letter of the Greek alphabet, is written as .
ionizing, electromagnetic radiation having high penetrating power. Similar to x-rays.
Electromagnetic radiation emitted in de-excitation of atomic nuclei, frequently occurring as a result of decay of radionuclides; also called gamma rays and sometimes shortened to gamma (for example, gamma-emitting radionuclide). High-energy gamma radiation is highly penetrating and requires thick shielding, such as up to 1 m of concrete or a few tens of centimeters of steel. See also photon and x radiation.
The electromagnetic radiation of high frequency emitted from nuclei when they decay from excited states, similar to but with higher energy than X-rays. See; Gamma Rays.
High energy electomagnetic radiation that is emitted from an atom's nucleus has no mass or electrical charge has high penetrating power, and can pass though the human body.
high energy electromagnetic radiation emitted durring radioactive decay; gamma rays have no mass or electrical charge.
See Ionizing radiation.
electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength
Extremely high energy radiation, wavelengths shorter than 0.001 nm.
An electromagnetic radiation of great penetrating power emitted by the nucleus of a radioactive substance.
Gamma radiation (or gamma rays) are a form of electromagnetic radiation. They can be written as 'Î³-rays'. The ABC of Radiation
Electromagnetic ionizing radiation which easily penetrates test biological tissue.
High-energy, short wavelength electromagnetic radiation emitted from the nucleus of an atom. Gamma rays are very penetrating and are shielded by dense materials such as lead. Gamma rays are similar to X rays.
Gamma rays are high-energy, ionizing radiation that travel at the speed of light and have great penetrating power. They can cause skin burns, severely injury internal organs, and have long-term physiological effects.
Gamma rays behave differently from particles. When a photon of such radiation strikes an atom, it ejects an electron from the atom thus ionizing it and producing an energetic electron. Ionizations break chemical bonds, they destroy molecules by breaking them up. One ionization in a gene can destroy its biological function.
Electromagnetic radiation emitted by excited atomic nuclei. It penetrates most solids.
Gamma radiation is a form of electromagnetic radiation emitted from the nucleus and is often emitted with alpha and beta particles. Gamma particles are uncharged, have no mass and travel at the speed of light.
High frequency electromagnetic radiation emitted during radioactive decay. Many centimetres of lead or metres of concrete are needed to absorb it. Radioactivity
Short-wavelength electromagnetic radiation of nuclear origin, with energies between 10 keV to 9 MeV.
gamma rays are electromagnetic radiation of short wavelengths emitted by the nucleus of an atom during a nuclear reaction.
(Also called gamma rays.) A very high frequency form of electromagnetic radiation that consists of photons emitted by radioactive elements. Gamma rays can injure and destroy body cells and tissue, especially cell nuclei.
High-energy electromagnetic radiation that in large doses is lethal to most living beings.
