This equipment uses two types of rays x rays and gamma rays to detect objects such as weapons, bombs and other explosives, and drugs.

X Rays

Gamma Rays

In 1876, the German physicist Eugen Goldstein showed that the rays from this glow cast a shadow, and he dubbed the rays cathode rays.

I'll take some X rays of your teeth.

He became an assistant at the school during the period of 1894 97 when he began the study of cathode rays and X rays.

Such equipment, which will be supplied to all remaining border posts in the near future, employs two kinds of rays, namely X rays and gamma rays, and seeks such contraband items as arms, bombs, explosives and narcotic drugs.

Because these latter rays passed through the holes, or channels, in the cathode, Goldstein called them Kanalstrahlen , or canal rays.

He also investigated the light spectra of gases and vapours, worked on the passage of electricity through gases, and discovered new properties of cathode rays (electron rays).

Each of the gamma rays has an energy of 0.511 MeV.

Many species of sharks and rays inhabit the surrounding body of water.

Those who live in the dark, are afraid of the sun's rays!!!

Cosmic rays comprise also high energy atomic nuclei, particularly that of iron.

Epsilon rays are a form of particle radiation and are composed of electrons.

He believed the rays to consist of streams of particles of ordinary molecular magnitude.

And this shows how I do my process of same size X rays.

Like all X rays, mammograms use doses of ionizing radiation to create images.

The coloring, so coloring adds another level to the X rays.

He observed tubes with energy rays extending from a negative electrode.

The hot diffuse gas in the Local Bubble emits X rays.

These rays produced a fluorescence when they hit the glass walls of the tubes.

The value of g for diagnostic x rays is only a fraction of a percent.

Small amounts of tritium occur naturally because of the interaction of cosmic rays with atmospheric gases.

They are themselves a cause of further warming ice and snow reflect the sun s rays.

One of these buildings was a dome which allowed the sun's rays to pass through.

In most cases, x rays will be taken of both clavicle bones for comparison purposes.

Compton observed in gamma rays, which do not penetrate the lower atmosphere.

You look at your X rays on a screen and you do stuff with them, you email them. But we were still using X rays, but we didn't even have a viewing box!

The lorry goes in front of it. And it takes slices of X rays through the lorry.

Indeed, Japan could become one of the few rays of light in an otherwise gloomy advanced country landscape.

It consists of a red field with a yellow sun in the center having 40 uniformly spaced rays.

The callus is the first sign of union visible on x rays,usually 3 weeks after the fracture.

Sun Study better than ever before how our own Sun produces gamma rays in solar flares.

He found that cathode rays were emitted perpendicularly from a metal surface, and carried energy.

The visual angle formula_10 is the angle between the chief rays for formula_5 and formula_8.

The number of the light rays in the Sun of the Presidential Seal were reduced to 16 (8 long and 8 short light rays, all of them sharp edged) in order to symbolize the 16 Turkic states in history, with another legal amendment on February 18, 1978.

His splendor is like the sunrise. Rays shine from his hand, where his power is hidden.

Its birth heralded the fact that cooperation and international brotherhood could bring rays of light to even the darkest of times.

Neutrino detectors are often built underground to isolate the detector from cosmic rays and other background radiation.

So, using large scale objects does sort of create drama because you just don't see X rays of big things that often.

Description of the phenomenon By the early 20th century, research into the interaction of X rays with matter was well under way.

The presence of the resulting antimatter is detectable by the two gamma rays produced every time positrons annihilate with nearby matter.

He discovered several important properties of cathode rays, which contributed to their later identification as the first subatomic particle, the electron.

He was an early investigator of discharge tubes, the discoverer of anode rays, and is sometimes credited with the discovery of the proton.

Electric fields are not ionizing radiation, like X rays or proton beams, that bombard tissue to disrupt DNA.
