How do you protect yourself from x rays?

In everyday life, there is no need to take special precautions against x-rays.

If you are getting a dental x-ray be sure to wear the apron shield that the dental technician will give you. Even though it is called a "lead apron," it is loaded with tin to block x-rays.

If you doctor suggests that you have a medical x-ray and you have had the same area x-rayed in the recent past, tell the doctor and help her determine whether the older x-ray will provide the information needed.

If you are working with an x-ray producing machine, follow the established protective procedures, avoid shortcuts, and maximize your distance from the x-ray machine when it is emitting x-rays. Use shielding (usually lead, tin or plastic) and work practices as specified by your radiation safety officer.

In general, if you work with a source of x-rays, minimize your time of exposure, maximized your distance from the x-ray source, use appropriate shielding

What is the medical term meaning process of taking a series of x-rays of an organ in depth?

Computerized tomography (or CT scan or CT or CAT scan) is the medical term meaning process of taking a series of x-rays of a body part or area in depth.

How long do you have to go to school to be and x-ray technician?

You can go to training and certificate programs schools for around a year if you want to become an X ray tech.

I am pregnant 40 days and had been exposed to X-rays indirectly before 20 days because I was in the same room when my son had a chest X-ray. Will this will be harmful for my pregnancy?

A two view chest x-ray series is not a significant dose of radiation and would most likely have no effect on the fetus. The greater the distance between you and your son at the moment of x-raying then the less exposure to radiation for you and your baby. Your exposure would be greatly reduced (90+ %) if you were wearing lead sheilding at the time. Consider that the X-ray beam is fairly directional with much of the beam's energy is directed toward the desired target - which is not you. This minor exposure will almost certainly not create a problem for the unborn child. It is vulnerable, but it is protected within you to a degree, and it is a very small target.

How can you help calm down a child who is scared of getting a x-ray?

when your child is at the doctors getting the shot.. you should tell your child that it's only going to be a couple seconds and when your child is finished.. reward him/her for doing a good job (wether it took 5 minutes or 5 seconds), him/her got the shot. also hold your child's hand and make sure wherever your child is getting the shot is nice and relaxed.. hope this helps. (:

What best describes the overall impact of Wilhelm roentgens discovery of X - rays?

NovaNet Answer: Doctors still ues his discovery to make images of the bodys insides.
It enabled diagnostic radiology, looking inside a person and making a diagnosis possible through radiation instead of by opening someone up.

One of this element's compounds is used to produce x-ray images of the intestinal tract?

Well the target inside of the tube is usually made of tungsten, molybdenum or possibly rhenium and that is where the beam of x-rays are actually produced. Then the beam is projected through the body and onto the film where many different elements could be used just in screen film. Calcium tungstate used to be a common film material, but now rare earth screens are more often used and they could be made of gadolinium, yttrium, lanthanum, etc. I'm not really familiar with what is used in computed or digital radiography yet though.

How much does it cost to get a chest xray?

A chest x-ray's cost varies. The price depends on where they are done at, how many are taken, and what if any amount insurance the person has will cover.

What do X rays cause?

It is able to see all bones in the body.

What is the medical term meaning X-ray of the bladder and ureters?

A cystogram is an x-ray of the bladder after contrast. You can also have a voiding cystogram, which looks at changes in the bladder during urination.Cystography is a radiographic, or x-ray, examination of the bladder after a contrast medium is instilled via a urethral catheter (cyst/o means bladder, and -graphy means the process of creating a picture or record). The resulting film is a cystogram

When is a CT scan more useful than an X-ray?

The medical X-ray is cheaper and much more accessible than other forms of imaging. The technology has been around a long time, and it is well refined, easy to use and comes with a good track record for accuracy. These things and a few others make the X-ray a front line medical technology.

What property of x-rays make them useful?

it creates vitamin D which is healthy for your bones.

Who may take X-rays in New York?

If there is any reason to believe that you may be pregnant you should not get an x-ray unless the Radiologist or Physician thinks that the benefits will outweigh the risks. Definitely make sure you get shielded with some lead when being exposed to x-rays no matter what age or gender.

How much is a cat-scan machine?

New or used?

I have seen used machines sell for as low as $10,000. ( keep in mind this is an older machine and probably wont give you the best images compared to the latest technology) But maybe that is all that is needed for the types of scans being done at that location.

I have seen newer machines sell for as little as $250,000 to well over $2,000,000. (yes that's 2 million) Its like the options when buying a car and you pay more for newest technology. Places buying scanners evaluate what options are required for the type of scanning they do.

Did Thomas Edsion invent the x-ray?

William Crookes first discovered the x-ray effect, but he didn't investigate it.

Tesla investigated the effect, but it was Röntgen who named them X and realized what was really happening, and thus Röntgen got the credit and the Nobel prize.

What are digital x rays?

It is an xray that is taken by a computer. Normal x-rays are taken when X radiation passes through you body and reaches a x-ray cassette with film in it. The more dense areas of the body (bones) absorb the x radiation and keep them from hitting the film (called partial absorbtion) thus the bone are lighter white color. Areas such a lungs which have air in them are not as dense as bone and do not absorb x rays thus they are black on film. Other areas with densitys between bone and lung (air) will result in different levels of grays. The film is exposed by the xrays that are not absorbed and partly absorbed by the body. Also it is key to note the xray cassette that hold the film has a screen inside it that is emits a light when hit with xrays. It actually the screen lighting up that exposes the film, which in turn is developed into the traditional xray film. In digital xray there is no film. The xrays expose a photo cell that is connected to a computer. Thus connected to a display. The nice thing about a digital xray is you can adjust the black and gray levels and send the image over the internet to radiologists all over the world. Hope this helps. Do take note that digital x-ray always to be confused with the x-ray radiation as being 'digital'. The fact is only image acquisition is digital and there is so such thing as digital x radiation.

Why is lead is used in xrays and xray shield?

Over-exposure can cause soft tissue damage, burns, sterility , and possibly cancer.

What are the advantages of using ultrasound instead of xray?

it does not damage tissues with ionizing radiation. Ultrasound is also generally far better than plain x rays at distinguishing the subtle variations of soft tissue structures, and can be used in any of several modes

If X-ray film is to dark what should you do?

If the film is too dark, the xray needs to be retaken with lower kV and mAS settings. Xrays that are only marginally too dark can be looked at under a bright light.

What is the difference between X rays and Microwaves?

The only difference is the frequency (or the wavelength, depending on which way you look at it). They are both part of the electromagnetic spectrum, as is visible light. For any wave, the wave speed is the frequency multiplied by the wavelength. So:

c = νλ

Where c is the wave speed in metres per second (m s-1), ν (the Greek letter nu) is the frequency in Hertz (s-1, also called cycles per second), and λ (the Greek letter lambda) is the wavelength in metres (m).

In a vacuum, the wave speed is constant at around 3.0 x 108 m s-1 (being the speed of light in a vacuum). So the wavelength is inversely proportional to the frequency.

X-rays have frequencies ranging from 3 x 1016 Hz to 3 x 1019 Hz, which gives them wavelengths ranging from 1 x 10-11 m to 1 x 10-8 m. This means they have higher frequencies (and shorter wavelengths) than visible light. Microwaves have frequencies ranging from around 1 x 109 Hz to 3 x 1011 Hz, so their wavelengths range from 1 x 10-3 m to 3 x 10-1 m. They have lower frequencies (and therefore longer wavelengths) than visible light.

The energy transferred by waves is proportional to the frequency. Since X-rays have higher frequencies than microwaves, they carry more energy. This is really the only difference between them.
