Gamma Rays | Science Mission Directorate
SOURCES OF GAMMA RAYS. Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.
Gamma ray - Wikipedia
Natural sources of gamma rays on Earth include gamma decay from naturally occurring radioisotopes such as potassium-40, and also as a secondary radiation from various atmospheric interactions with cosmic ray particles. Some rare terrestrial natural sources that produce gamma rays that are not of a nuclear origin, are lightning strikes and terrestrial gamma-ray flashes, which produce high ...
gamma ray | Definition & Applications | Britannica.com
After detection of the gamma rays, a computer-generated reconstruction of the locations of the gamma-ray emissions produces an image that highlights the location of the biological process being examined.
Gamma rays | Define Gamma rays at Dictionary.com
gamma ray A stream of high-energy electromagnetic radiation given off by an atomic nucleus undergoing radioactive decay. Because the wavelengths of gamma rays are shorter than those of x-rays, gamma rays have greater energy and penetrating power than x-rays. Gamma rays are emitted by pulsars, quasars, and radio galaxies but cannot penetrate the ...

X-rays, Gamma Rays, and Cancer Risk
When talking about radiation and cancer risk, it is often x-rays and gamma rays that people think about.
Incredible hulking facts about gamma rays | symmetry magazine
From lightning to the death of electrons, the highest-energy form of light is everywhere. Gamma rays are the most energetic type of light, packing a punch strong enough to pierce through metal or concrete barriers. More energetic than X-rays, they are born in the chaos of exploding stars, the ...
What Are Gamma Rays - Universe Today
So what are gamma rays? Gamma rays are the strongest from of radiation. This is what makes nuclear radiation so dangerous. This high energy form of radiation can damage human tissue and cause mutations.
Gamma-ray astronomy - Wikipedia
Gamma-ray astronomy is the astronomical observation of gamma rays, the most energetic form of electromagnetic radiation, with photon energies above 100 keV. Radiation below 100 keV is classified as X-rays and is the subject of X-ray astronomy.
