X-Ray

Two reasons. Firstly, Safety. Fetus have a higher rate of cellular division than the average human being. A damaged gene while still developing can cause birth defects. Secondly, X-rays really only give an idea of bone structure and generally aren't live. It X-rays don't give as clear an indication on lung and heart development.

While Crick, Wilkins and Franklin all used X-ray diffraction to try and decipher the molecule of DNA the best work was done by Rosalind Franklin with here B-51 diffraction " picture " of the double helix.

Considering it uses radiation, then yes it can cause cancer. Only under extreme exposer will it do that though. Getting X-rays is harmless unless you do it for hours continuously, well then you'll just die.

Yes and No. Tumours can show up X-rays simply as a mass which shouldn't be there. There is no way or not to tell if it is cancer from a standard X-ray. However if anything suspicous is seen, futher tests are normally ordered which will give the doctors more details. Lung Cancer is often found on a routine chest X-ray and appears as a "suspicous shadow" that warrants futher investigation.

That would be the Projection

X-Rays normally detect foil because it is metal.

to find broken ,or cracked bones, or to find bad things.

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

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.

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

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.

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.

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.

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.

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.

It is able to see all bones in the body.

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

The cathode of an electron gun.

no the do not

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.

it creates vitamin D which is healthy for your bones.

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.

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.
