Every so often the sun emits a gigantic burst that includes highly energized x-rays gamma rays and charged particles.
Either way, one sign of dark matter particles, researchers think, is a burst of annihilation-induced gamma rays.
Cell phones produce "non-ionizing" radiation, which, unlike X - or gamma rays, doesn't damage DNA by stripping away electrons from molecules in cell tissue.
Strictly speaking, it is impossible to absorb all gamma rays.
The most damaging radiation are gamma rays and x-rays; energetic alpha rays (streams of helium nuclei) and beta rays (electrons) can also damage cells.
The supernova explosions that create and spread heavy elements also unleash a torrent of high-energy radiation: gamma rays, X-rays, and ultraviolet light.
It can measure the gamma rays that the uranium emits when it spontaneously breaks up in pieces and energy is released we call that fission.
Positrons and electrons annihilated each other, emitting gamma rays detected by Fermi's gamma-ray burst detector, researchers said.
But how can terrestrial gamma rays reach Fermi's orbit in space?
Gas from the star falling into the black hole could have triggered the gravitational monster to emit a jet of X-rays and gamma rays that by chance happens to point directly at Earth.
Meanwhile, the newly real particles decay, giving off (among other things) light, X-rays and gamma rays.
Some of these gamma rays pass near atomic nuclei, in the process transforming into an electron and a positron, researchers said.
Further, both gamma rays and neutrons can produce harmful effects in living organisms.
Food is irradiated by brief exposure to X-rays, gamma rays or an electron beam.
The act or process of destroying most microorganisms in certain foods, such as fish or clam meat, by irradiating them with gamma rays or other radiation to prevent spoilage.
Other forms of radiant energy familiar to us are radio waves, infrared rays, ultra - violet rays, X rays, and gamma rays.
The Fermi Space Telescope found hints in 2009 of the telltale pattern associated with positrons in terrestrial gamma rays stemming from lightning storms.
The distant storm was below Fermi's horizon, so any gamma rays it produced could not have been detected.
