X-Ray

No, an X-ray is not a mechanical wave. An X-ray is an electromagnetic wave. However, in polar molecules, an X-ray can cause the molecule to vibrate rapidly, just like a microwave oven can.

what constitutes a financial objective of a firm is the goals, long range planning and business. while that of the economic objective has to do with enviromental scanning and swot analsis

stop telling them you are a title 19 patient

They do not show up on regular x rays

"Blunting of left c.p angle"

can you please explain the above mentioned x-ray result. Is this is a major problem....

An x-ray tech certification is a program that's offered through many communities colleges and technical schools. Upon completion of the program, the student is certified to operate an x-ray machine, but not to read the results.

A radiology technician normally makes more than a surgical tech. The average yearly earnings of a radiologic tech is around $56,000 while a surgical tech averages $41,000 a year.

Basically,there is no exams have to swallow tube in x-ray field, but as for internal medicine such as colonoscopy,endoscopy for stomach and ERCP for gall bladder has to use long tube with the camera which is located on the end of the tube.

They can easily go through objects

Chest x-rays are complicated to read as numerous shadows are visible and some are perfectly harmless whilst others may not be. Among the things that may show as a shadow on a chest x-ray are nipples, the aorta, infections, fluid, arteries and veins etc.

to figure out how much radiation is needed to go thru body ........inverse square law

Wilhelm roentgen the inventor invented it on accident he was studying cathode rays and some electrodes had to much power on them so it casted a shadow on the wall of the bottle and it was invented like that, an accident

An x-ray before you get pregnant is completely safe, there is no lingering radiation effect. Even during pregnancy if a physician prescribes an x-ray for your health there are measures that can be taken to protect the developing baby, though it is probably better to hold off until the second trimestyer when the baby is fully formed. When I trained as a midwife in the late 70's, if there appeared to be a possible problem, some women were still having x-rays at around 38 weeks to check if the baby would fit through the pelvis. In fact they weren't very helpful as the pelvis can stretch amazingly toaccommodate the baby and the baby's skull can alter in shape to be born.

The study of high-energy, electromagnetic radiation, which includes x-rays, is called atomic spectroscopy.

The study of nuclear radioactivity and decay is called nuclear physics.

For the study of electromagnetic radiation of energies below x-rays you have:

UV - UV spectroscopy

Visible Light - gaffer

Infra-red - infrared spectroscopy

Microwave - microwave spectroscopy

Radio - amateur broadcaster

I did this test in Canada and there were a total of 4 orbital xrays taken. Not sure if this differs between countries. One when I was looking up, one when I was looking down, one positioned sideways to my left and one positioned sideways to my right.

How many chest x_rays can be conducted in ayear for safe life

Wilhelm Röntgen was the one who gave them the name "X-rays", though many referred to these as "Röntgen rays" for several decades after their discovery. The presence of some unknown ray was deduced from its effect on photographic film/plates when sealed in light tight containers. Röntgen referred to the radiation as "X", to indicate that it was an unknown type of radiation. The name stuck, although (over Röntgen's great objections) many of his colleagues suggested calling them Röntgen rays. They are still referred to as such in many languages, including German.

Well it really depends on what type of x ray you are talking about. If its a major one like a ct scan it may cause some difficulties, but not for certain. I work as a dental assistant, we take digital x rays every single day. My coworker didn't know she was pregnant and was exposing 100's of images on a daily basis. She delivered a very healthy baby boy with no complications. Usually if the x ray is the newer digital types you are getting almost zero radiation, I mean staying out in the sun all day you will receive more radiation than having some digital x rays taken, and pregnant women walk out in the sun all the time. Also, if you received an x ray you should have had some sort of lead covering on that would protect you and your baby from any extra scatter radiation that may have happened. Therefore, chances of your baby getting any radiation that could have harmed them from one x ray are slim.

MRI's do not use radiation.

N.e.r.d.s

Yes but the level of exposure that the average person would have to receive in order for that to occur is typically more than the typical diagnostic exposure time a patient would receive on a single visit. While CT's to give the most exposure at one time, unless it was a direct shot to the testes, one CT is unlikely (thought not impossible. There are rare exceptions to all cases with radiation) that it would happen. X-rays are far lower dosage and shielding of a patient's reproductive organs is typically done by technologists at all possible times.

No

In the UK they're called Radiographers. In the US, they are known as medical technologists.

It is not known when Pastor Kimberly Ray was born. Kimberly Ray is the daughter of the late Dr. Angie Ray.
