A gamma ray, also known as gamma radiation (symbol γ ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic...

electromagnetic radiation consists of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) particle...

electromagnetic spectrum. Gamma rays, X-rays, and the higher energy ultraviolet part of the electromagnetic spectrum are ionizing radiation, whereas the lower...

wavelengths—much smaller than an atomic nucleus. Gamma rays, X-rays, and extreme ultraviolet rays are called ionizing radiation because their high photon energy is...

887 seconds (14 minutes, 47 seconds). Neutron radiation is distinct from alpha, beta and gamma radiation. Neutrons may be emitted from nuclear fusion or...

area radiation monitor will measure the ambient radiation, usually X-Ray, Gamma or neutrons; these are radiations that can have significant radiation levels...

in a gamma radiation background, which could increase the total reading above that expected from the contamination alone. However, if no radiation source...

on radiation-induced mutagenesis in plants. During the period 1930–2004, radiation-induced mutant varieties were developed primarily using gamma rays...

lowercase gamma are Γ and γ. Greek Gamma Coptic Gamma Latin Gamma / phonetic Gamma CJK Square Gamma Technical / Mathematical Gamma These characters...

Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed...

two-stage neutron-gamma pumping, in which neutron capture occurs in a parent-doped converter, where it generates Mössbauer radiation that is then absorbed...

surface and internal burning. Depending on the photon energy, gamma radiation can cause deep gamma burns, with 60Co internal burns common. Beta burns tend to...

A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique...

particles are a type of ionizing radiation and for radiation protection purposes are regarded as being more ionising than gamma rays, but less ionising than...

Radiation originating from earth is also a major contributor to background radiation. Another limitation of gamma radiation detectors is that gamma photons...

by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay...

to radiation. Some of the mutations produced thereby have turned out to be useful. Typically this is gamma radiation – in which case it is a gamma garden...

distant galaxies. Gamma-ray bursts were first observed in the late 1960s by the U.S. Vela satellites, which were built to detect gamma radiation pulses emitted...

ultraviolet. UV, with X-ray and gamma radiation, are referred to as ionizing radiation due to the ability of photons of this radiation to produce ions and free...

A gamma-ray spectrometer (GRS) is an instrument for measuring the distribution (or spectrum—see figure) of the intensity of gamma radiation versus the...
