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

But the potential advantage was that gamma rays, unlike X rays, are not influenced by breast density.

Do I need X rays?

Ultraviolet rays can cause skin cancer.

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.

It has parallel lines, which are sun rays.

X rays, useful when you go to hospitals.

Dentists take x rays to examine your teeth.

The doctor used X rays to examine my stomach.

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!

So this seems to be a feature of ultraviolet rays hitting the skin.

You don't want to get close to gamma rays, it could be dangerous.

Within this band are gamma ray pulsars and other unidentified sources of gamma rays.

They take all the parallel incoming rays and focus it to a single spot.

Are there any other rays of light that could make it into the eye?

Yes! The rays would lie on a I'd like to see yeah, on a cone.

It uses X rays, X ray beams, that are rotating very fast around the human body.

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

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

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

But on the front step, a person who was sitting there blocked the rays from hitting the stone.

So let's look at this in the context of the entire electromagnetic spectrum, where we have gamma rays.

You can see that there is a scattering of X rays on the teeth, the metal in the teeth.

to the East where he found the sun rising upon a people whom We had exposed to its rays.

But isotopes, particles of electricity, antimatter, neutrinos, the conversion of mass to energy that's E mc 2 gamma rays, transmutation.

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

The reason I have this picture here, this X ray, it's just to tell you where and how we were viewing X rays.

As they sang of liberty, the setting sun s rays dazzled the prisoners and the Oxfordshire audience. Nature underlined the importance of the message.

Rays of light in this case, microwave light come in, and they just squish around the cell, and they come back the other side.

We see the same pattern now with these tags we're seeing a similar pattern for swordfishes, manta rays, tunas, a real three dimensional play.

I had just taken trigonometry in high school, I learned about the parabola and how it could concentrate rays of light to a single focus.

It's hotter in summer than in winter because the rays from the Sun are spread out more, right, because of the tilt of the Earth.

Space physicists using the Solar, Anomalous, and Magnetospheric Particle Explorer (SAMPEX), launched in June 1992, discovered a radiation belt of trapped anomalous cosmic rays in the magnetosphere.

They usually have about a one degree acceptance angle, meaning once they're more than about a degree off, none of the sunlight rays will hit the focus.

Now, what we were careful to do was, vitamin D is made by ultraviolet B rays and we wanted to separate our story from the vitamin D story.

So there's a whole ray of light rays of light on a cone that will all be bent by that cluster and make it into the observer's eye.

Generally radiological facilities including X rays and ultrasonographs are also provided free of charge or at nominal cost though there is a long waiting list for these facilities.

It will monitor energetic X rays from solar flares and survey the sky with X ray charge coupled device (CCD) sensors along an axis perpendicular to the Sun line.

We brought patients in, six to eight weeks prior to their scheduled surgery, did X rays, and we then composed a scaffold specifically for that patient's size pelvic cavity.

For two years, I searched for a fiber that could survive ultraviolet rays, salt, air, pollution, and at the same time remain soft enough to move fluidly in the wind.

Astronomers analyzing EGRET apos s data have also identified what they think are massive black holes in the middle of distant galaxies that are sending gamma rays in Earth apos s direction.

They have determined the chemical composition and electrical charge of these rays in the region beyond the Earth apos s upper atmosphere where the planet apos s magnetic field affects charged particles.

And when we shone UV at them, or when we warmed them up to the same level as the lamps, but didn't actually let the rays hit the skin, this didn't happen.

When they bombed Hiroshima, the explosion formed a mini supernova so every living animal, human or plant that received direct contact with the rays from that sun was instantly turned to ash.
