Gamma decay Gamma decay, type of radioactivity in which some unstable atomic nuclei dissipate excess energy by a spontaneous electromagnetic process. In the most common form of gamma decay, known as gamma emission, gamma rays (photons, or packets of electromagnetic energy, of extremely short wavelength) are radiated. Gamma decay also includes two other electromagnetic processes, internal conversion and internal pair production.

Radioactivity Gamma rays are electromagnetic waves of very short wavelength and high frequency. Gamma rays are emitted by most radioactive sources along with alpha or beta particles. After alpha or beta emission the remaining nucleus may still be in an excited energy state. By releasing a gamma photon it reduces to a lower energy state.

How they're made How they're made. Gamma rays are given off by stars, and by some radioactive substances. They are extremely high frequency waves, and carry a large amount of energy. They pass through most materials, and are quite difficult to stop-you need lead or concrete in order to block them out.

- X-rays and gamma rays. X-rays and gamma rays are used in medicine. They are electromagnetic waves and part of the electromagnetic spectrum. X-rays and gamma rays have some other features in common.his machine allows the energy and intensity of the x-rays to be controlled. Gamma rays, on the other hand, are given out by radioactive materials. This process is totally random and so cannot be controlled as easily as x-rays. Page: 1  1.

- X-rays: The overarching focus of this page, and how we might see a broken bone in the body. Gamma rays: Produced by a particular kind of radioactive decay called gamma decay, as well as some other things like lightning for instance. X-rays span a range of wavelength, frequency and energy: Wavelength ranges from 10 nanometers to 0.01 nanometer.

gamma rays gamma rays, n an electromagnetic radiation of short wavelength emitted by the nucleus of an atom during a nuclear reaction. Composed of high-energy photons, gamma rays lack mass and an electric charge and travel at the speed of light.. immune globulin. gamma rays (γ-rays) electromagnetic emissions from radioactive substances; they are similar to and have the same general properties as x-rays but are produced through the disintegration of certain radioactive elements.

What Are the Benefits of Gamma Rays? Gamma rays are common in outer space and are created by very hot objects, such as neutron stars and the areas around black holes. Scientists use the gamma rays emitted from the nuclei of the elements found on planets to determine the material that comprises the planet.

Gamma Rays The gamma rays are just like other electromagnetic rays which are emitted by different sources under different circumstances. These are emitted by the hottest part of our universe and also these are emitted by the radioactive decay of certain material, like cobalt-60, zinc-65, cesium-137, and radium-226.

Gamma ray Gamma rays are emitted during nuclear fission in nuclear explosions. Gamma ray (also called gamma radiation), denoted by the lower-case Greek letter gamma (γ or γ {\displaystyle \gamma } ), is penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei. It consists of photons in the highest observed range of photon energy.

Gamma ray The energies of gamma rays from astronomical sources range to over 10 TeV, an energy far too large to result from radioactive decay. A notable example is extremely powerful bursts of high-energy radiation referred to as long duration gamma-ray bursts, of energies higher than can be produced by radioactive decay.

What Are the Benefits of Gamma Rays? Gamma rays are also used in PET scans and bone scans to detect malignancies. Medical personnel use an isotope of cobalt called cobalt 60 as a source of these gamma rays. Gamma rays are also used in autoclaves to sterilize medical instruments. These high-energy rays are also used in the food industry to irradiate food.

- Gamma Radiation. Gamma radiation is one of the three types of natural radioactivity. Gamma rays are electromagnetic radiation, like X-rays. The other two types of natural radioactivity are alpha and beta radiation, which are in the form of particles. Gamma rays are the most energetic form of electromagnetic radiation, with a very short wavelength of less than one-tenth of a nanometer. Gamma radiation is the product of radioactive atoms. Depending upon the ratio of neutrons to protons within its nucleus, an isotope of a particular element may be stable or unstable.

What are gamma ray bursts? These gamma ray bursts (GRBs) are the most powerful singular events in the universe. They’re thought to be messages from the beginning of time when the most massive stars in existence violently collapsed. GRBs were discovered by accident while looking for a very different kind of electromagnetic outburst.
