Electon microscopes can cost up to $200,000, but the older models can be as low as $50,000.

An X-ray is a type of medical scan. Several types of scanning tests can be used to make a diagnosis, depending on the situation. An X-ray is primarily used to determine if there is damage to bones such as a fracture or dislocated joint, locate a foreign object (i.e., bullet, a swallowed toy, etc), diagnose certain diseases (example-pneumonia) or to get a general idea of where to focus a more detailed scan of soft tissues. It is performed by placing the patient between a specialized type of film and a radiation source, which can be targeted at any given point of the body. It creates a picture that is then viewed by an X-ray technician, nurse, physician assistant or physician in order to help make his/her diagnosis. There are also CAT scans, MRI's, ultrasounds, and PET scans, all of which use different technology to be able to view inside the body in varying levels of detail.

X-ray tech's AKA Radiologic technologists earned $52,336 on average in 2007. More experienced radiologic tech salaries ranged between $50,000 to $80,000, according to the American Medical Association. Radiologic tech salary is dependent on several factors. For example, the type of facility you work in and the geographic location of your workplace can have an impact on your salary level.

when the cathode filament emits the electron and because of the high vaccum inside the tube with a high voltage who is applied on anode (the destination) the electron will accelerate to the anode and the anode will emits the x-ray photon directly after strike of the mentioned electron.

the power of x-ray or peneration is determined of the anode high voltage.

When the x-rays enters the body,it recogonises the shape of the structures.It is then obtained on the computer.If there is a mistake in the correct shape,the doctors finds the bone breakage.

Lead. Lead is a heavy metal that protects against x-ray and some forms of radiation.

The main purpose of a chest x-ray before having surgery is to ensure your lungs are healthy enough to be intubated. You will have a breathing tube placed down your throat while you are having surgery and if your lungs are not healthy then you might not be able to have the surgery.

Most Doctors do not take Xrays- they are ordered by the Doctor, taken by a Radiology Technician, and read by a Doctor- frequently by a Radiologist.

X-rays have a higher frequency; therefore, a shorter wavelength, than radio waves. Xrays have a higher energy than radio waves.

Radio waves travel easily through the atmosphere. X-rays suffer significant attenuation passing through the atmosphere.

Radio waves are non-ionizing, not carrying enough energy per quantum to ionize atoms or molecules-that is, to completely remove an electron from an atom or molecule. The electromagnetic radiation of radio waves has sufficient energy only for excitation, the movement of an electron to a higher energy state.

X-rays are ionizing, producing charged ions when passing through matter. X-rays will deposit images on photographic plates (radio waves will not).

Its rare for a person to get cancer from an x-ray, but it's better to be safe than sorry. I wouldn't take any chances not to check for cancer so women get mammograms just to be safe.

When X-ray radiation passes through a patient, three types of interactions can occur, including coherent scattering (coherent scatter), photoelectric absorption and Compton scattering . Of these three events, the great majority of scattered X-rays in diagnostic X-ray imaging arise from Compton scattering.

In coherent scattering, the energy of the primary X-ray photon is first completely absorbed and then re-emitted by the electrons of a single atom. Because no net energy is absorbed by the atom, the re-emitted X-ray has the same energy as the original X-ray, however the direction of re-emission is totally arbitrary.

In photoelectric absorption, the energy of the X-ray photon is completely absorbed as it ejects a tightly bound electron from one of the atom's inner shells. The excess energy of the photon over that of the binding energy of the electron is carried off as kinetic energy by the ejected electron. Low energy characteristic radiation is generated as an electron from an outer shell falls into the vacated lower shell.

Finally, in Compton scattering, the interaction can be considered as a collision between a high energy X-ray photon and one of the outer shell electrons of an atom. This outer shell electron is bound with very little energy to the atom and essentially all of the energy lost by the X-ray photon in the collision is transferred as kinetic energy to the electron, and the electron is ejected from the atom. Because energy and momentum are both conserved in this collision, the energy and direction of the scattered X-ray photon depend on the energy transferred to the electron. When the initial X-ray energy is high, the relative amount of energy lost is small, and the scattering angle is small relative to the initial direction. When the initial X-ray energy is small, the scattering is more isotropic in all directions. At X-ray energies on the order of 1 MeV (the energy range used in radiation therapy), the scattering is mostly in the forward direction. At X-ray energies of 100 keV (the diagnostic imaging range), the scattering is more isotropic.

Depends what you consider 'high'.

The scientific unit of measurement for a dose of radiation, which is also called an effective dose, is the millisievert (mSv). This is also at times measured in rads, rems, roentgens and sieverts.

For an X-ray of a limb, the typical effective dose is 0.001 mSv. This is a comparatively small dose, and often talked about in relation to how much natural radiation from the earth to which it compares. In this case, it is equal to the natural background radiation you would get in less than one day.

Although many people would not fully understand this electron diffraction gives you only one plane. X-Ray diffraction will give you a scattering of all the planes in one measurement.

No. X-rays are generated by a vacuum tube, something like the picture tube in an old-style TV. The regions of the electromagnetic spectrum identified as "X-rays" and "gamma rays" overlap; radiation resulting from an electronic energy transition is an "X-ray" and radiation resulting from a nuclear process is a "gamma ray" even if the two have exactly the same wavelength.

Should be UVA and UVB. Read the labels, and use at least SPF 15 up to SPF 30 if you are very fair or freckle easily.

A good used portable digital X-ray machine can be purchased from a reliable agent for something in the range of $7,000 to $7,500. That's about the least you can spend. Certainly prices go up from there.

Some harmful effects due to human exposure to ultraviolet rays would be:

A risk of skin cancer for being out in the sun too long.

Also you could get a sunburn. Which is very painful.

they are fast ,they are less expensive ,they use lower amount of radiation

Nausea and vomiting are most likely to occur when the radiation dose is high or if the abdomen or another part of the digestive tract is irradiated

Tooth x-ray, also known as dental radiography, is using low energy radiation. If what you mean by tooth x-ray is orthopantomography (OPG), the dose is slightly higher. There are risks of unwanted effects to your baby especially during the first trimester. Unless the x-ray is emergency, I recommend you to postpone.
