X-Ray

X-rays are a form of electromagnetic radiation just like visible light. They travel at the same speed (299,792 km/s in a vacuum) as visible light. The only difference is that x-rays have a much higher frequency (~10^18 Hz) and hence a much shorter wavelength (~1 nm) than visible light.

An X-ray is a highly energetic form of electromagnetic radiation. It is like visible light, only of higher frequency (shorter wavelength).

You are a bit confused. They don't. If you mean "why are X-rays held up to the light to see details," that's different. X-ray film turns dark when irradiated. Then the film is developed so that people can examine it. I don't agree. X-Rays are a form of light. A light, precisely. However, they do not "use" light waves, and the person above me is wrong in that sense, and does not know that X-Rays are a form of light. They don't use light waves, they are simply in that form - light waves - because that is how they work. I don't know quite how to explain it, but it is not a sound wave or any other type of wave, only light. They are very small, which is why X-Rays show your bones. However, they have radiation effects. (Notice that radiate means to radiate heat, which comes from light?) These effects can only happen with light waves.

you already "KNOW". bY SPANKING THEM and licking them in their Face......

Electromagnetic waves comes in different frequencies; at higher frequencies, the wavelength is shorter. So, X-rays have a shorter wavelength, a higher frequency, and more energy per photon, than infrared light.

Yes living x-rays are a danger to living organisms. x-rays cause ion pairs the damage molecular pairs

Dense materials such as bones and metals block X-rays.

Bone is evident on an x-ray because it is denser than the surrounding muscles and fat. This means that the bone stops some of the x-ray beams from reaching the x-ray film, leaving that area on the film white. That is why bone x-rays appear white on a black/grey background.

A human fetus is still early in the stages of development and if hit with X-rays can cause damage or defects in the fetus' body. The radiation could cause many problems within individual cells, including the damaging of receptor proteins which could cause cancerous tumors to grow. A human fetus, or any other fetus, is more susceptible to radiation damage because many of their cells are still stem cells (cells that can continue to divide endlessly and haven't been defined as a certain cell). In other words these cells aren't specified yet, they could become skin cells or stomach cells so radiation could mutate them and since they can divide easily the defect could easily spread.

How often you get a chest x-ray is dependent on signs and symptoms following a positive PPD read. If no signs and symptoms are present once every ten years is standard. They also have the ability now to have blood drawn and tested yearly for Healthcare workers as opposed to chest x-rays. If signs and symptoms are present then your family Dr will do labs along with chest x-ray.

Fluoroscopy is the visualization of body parts in motion by projecting x-ray images on a luminous fluorescent screen (fluor/o means glowing, and -scopy means visual examination). Luminous means glowing.

An x-ray image of the brain is a "cerebral angiography."

The use of the X-ray machine as a diagnostic tool in medicine has resulted in cured illnesses and extended lives. The X-ray is also used in engineering for research and as a diagnostic inspection tool.

We know that X-rays can be harmful. They can damage body tissue. Because of this, when we use X-rays to aid in medical diagnosis, we want to expose only the area of interest to the incident beam of the machine. We'll protect other areas as necessary using lead blankets. X-ray staffers know where to place the blankets, and they arrange them to protect other body parts. It's a sure bet that reproductive organs will be hidden under those blankets.

Ground glass infiltrates look exactly like ground glass on an x-ray. They are indicative of restrictive lung disease and usually range from mild to severe depending on the amount of infiltrates. Diagnosis might range from pleral issues to pneumonia.

Quanta of X-ray carry less energy than gamma-ray quanta.

Similar to a photograph, the x-rays (the actual RAYS) hit the object it's supposed to hit and then reflects off of whatever was blocking it and a special "machine-thingy" prints the image on a piece of that shiny paper via the ray-pattern it sends back to the paper. [:<

Actually cystal is a three dimensional grating with grating element(interplanar spacing)as of the order of 1 angstron unit. Also the wavelength of X rays is of the order of 1 angstron which satisfies basic condition of diffraction(Bragg's law). Gamma rays are not used for the same reason as well as gamma ray production is not high enough, difficult to focus and high intense enough to create particl and antiparticle.

hello i am bored so i thought id write an answer for this in btec science thats right btec science because im an idiot uand your a weirdo thankyou this is not the correct answer by the way

X-rays are a form of ionizing radiation, similar to the gamma rays from nuclear radiation. These forms of radiation are highly-penetrating, and they damage or kill cells deep within the body. People who work with these types of radiation on a regular basis want to avoid damage to their bodies, and so they take protective measures to minimize their exposure.

It would be extremely difficult to conceal jewelery in an x-ray particularly if the jewelery is metal. Even pearls and diamonds show up on x-rays. Cheap, thin plastic beads might not be visible on some x-rays.

I've had it with and without. When they check my bite, the put a small piece of plastic in you back teeth. When the check my braces, they just have a machine that swerves around my head. I think it just depends on your dentist.
