gamma rays

You can heat the biomass, irradiate it with gamma rays, grind it into a fine slurry, or subject it to high-temperature steam.

Some of these gamma rays pass near atomic nuclei, in the process transforming into an electron and a positron, researchers said.

He said in its first year of a five-year mission, the Fermi telescope has discovered over 1, 000 places that stream gamma-rays.

Some antiproton annihilations produce a shower of positrons, which in turn produce 511-keV gamma rays, two of which may be detected.

He believes that this process supplies the gamma-rays observed by Fermi.

Visible light makes up less than one ten-billionth of the electromagnetic spectrum, which stretches from radio waves to gamma rays.

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.

It was so bright that Integral was able to measure the polarisation of its gamma rays accurately.

Every so often the sun emits a gigantic burst that includes highly energized x-rays, gamma rays, and charged particles.

If the particle were then to decay into an electron and a ground-state dark matter particle, the electron would release gamma rays.

These high-energy gamma rays, detected by Fermi's Large Area Telescope (LAT), have wavelengths one-thousandth the size of an atomic nucleus.

Very-high-energy gamma rays may be slowed down as they propagate through the quantum turbulence of space-time.

The telescopes are designed to detect gamma rays, the most energetic form of light.

The Crab Nebula is the brightest source of reasonably steady high-energy radiation (X-rays and gamma rays) in the sky.

Magnetars, so rare that only a dozen or so have been discovered, routinely emit high-energy x-rays and even gamma rays.

The nuclear-cement log is similar to a density log in that it contains a gamma ray source and measures the backscattered gamma rays.

New NASA telescope GLAST can detect gamma rays and will reveal aspects of the universe unexplored by man so far.

In other words, if these theories accurately describe nature, high-energy gamma rays travel slightly slower than the speed of light.

The other device can detect the distinctive gamma rays produced by collisions of neutrons with the atoms of different chemical elements.

Other forms of radiant energy familiar to us are radio waves, infrared rays, ultra-violet rays, X rays, and gamma rays.

A radio wave is of the same family as heat waves, light waves, X-rays and gamma rays.

Electromagnetic radiation is optical light, infrared, ultraviolet, radio, x-rays, gamma rays.

But while it is unlikely that any of us were born on Krypton, technology can help us when nature and gamma rays can't.

One signature of positron-electron annihilation is gamma rays carrying 511 thousand electron-volts (keV) of energy.

Either electrons or protons in the jet could interact with light photons or matter to create the extremely high-energy gamma rays.

Fermi is designed to monitor gamma rays, the highest-energy form of light.

Either way, one sign of dark matter particles, researchers think, is a burst of annihilation-induced gamma rays.

The gamma-ray detector spotted the antimatter signals while searching for at terrestrial flashes of gamma rays.

When these electrons are deflected by molecules in the atmosphere, they emit gamma rays.

Positrons and electrons annihilated each other, emitting gamma rays detected by Fermi's gamma-ray burst detector, researchers said.

Seeing gamma-rays from this kind of stellar outburst was unexpected - this is the kind of surprise that we love to find.

Bituminous mixtures - Test methods for hot mix asphalt - Part 7 : determination of bulk density of bituminous specimens by gamma rays.

Gamma rays and other penetrating radiation can cause cancers and other long-term illnesses or, in high amounts, near-term illness or death.

Meanwhile, the newly real particles decay, giving off (among other things) light, X-rays and gamma rays.

Further, both gamma rays and neutrons can produce harmful effects in living organisms.

Collisions of dark matter particles, the theory goes, could produce showers of gamma rays.

Recording this light allows astronomers to trace the gamma rays back to their cosmic sources.

And this object, this pulsar in the Crab Nebula is radiating copious amounts of x-rays, of gamma rays.

Gamma rays: high-energy invisible light that can damage tissue and is most dangerous to humans.

Technetium-99, a fission product of nuclear reactors that emits gamma rays, is the most-used tracer isotope in nuclear medicine.

These observations also reflect the direction the gamma rays came from, though they are not very precise.

A radioactive source is used to bombard the rocks surrounding the wellbore with gamma rays.

High energy hot spots in the universe are revealed with gamma-rays, said Michelson.

These gamma rays arise when high-velocity particles called cosmic rays collide with each other.

Food is irradiated by brief exposure to X-rays, gamma rays or an electron beam.

This burst had a 135 second long, broad peak of emission in gamma rays.

The distant storm was below Fermi's horizon, so any gamma rays it produced could not have been detected.

But how can terrestrial gamma rays reach Fermi's orbit in space?

According to calculations, the tiny grains would affect the way that gamma rays travel through space.

The gamma rays HESS sees are mostly by-products of extremely violent astrophysical events such as supernovae and flaring black holes.

This morning we noticed that one of the many active galaxies in the Fermi sky had become extremely bright in gamma-rays.

Instead they would produce gamma rays, neutrinos and antimatter such as positrons and antiprotons, Gondolo said.

And it can distinguish between gamma rays and beta particles, which is necessary to determine the level of contamination.
