Google re-remind the world of 115 years of X-ray

Is a type of electromagnetic radiation wave length from 10 to 0.01 nm means that the energy rays between 120 electron volts (eV) and 120 thousand electron volts (keV). X-ray used in many medical fields, it gives clear pictures of the bones, which appear white, air and tissue appear black,

Discovered the German scientist William Roentgen in 1896 in Würzburg University, and earned him the Nobel Prize in Physics in 1901. Uses of

* Radiography in medicine for the detection of the teeth and bones and fractures and to locate solid objects such as shrapnel or bullets in the body, and so is to detect tumors in the body,
* Treatment of malignant tumors and eliminate them. X-rays kills cancer cells and destroy them, the body's healthy cells, they regain its vitality after a period of convalescence and return Amaavip sound.
* In the industry are used to measure thickness and detect flaws and quality control and quality in the manufacture of metal alloys and parts used in automobiles, aircraft and others.
* In the area of security X-ray used in the control of passenger baggage at airports for weapons or bombs
* In the study of solid objects as he was using the X-ray diffraction proved the existence of a certain symmetry in some types of solids (crystals) and was the beginning of a powerful breakthrough in the study of the properties of solids and crystal structure, and knowledge of the atomic structure of the elements.
* In the field of art used to identify the methods of the painters and the distinction between paintings of real and paintings counterfeit, because the colors used in the paintings of old contain a lot of metal compounds that absorb X-rays, and the colors used in the modern pictures are organic compounds that absorb X-rays in smaller quantities.

Published X-ray in two ways:

* By speed (acceleration) and charged particles are usually electrons - and these rays are Ankabbah Bremsstrahlung which is nice going (any combination of electromagnetic waves short and very short).

* Or when the electron transitions in the cover of an atom or molecule of a very high level of energy to a low level. This is the unique X-ray wave length specific, and have a specific energy.

And exploit both cases, the valve in the X-ray, originating at the cathode glow of electrons (such as the Flared fuse fuse bulb) and speed and then lift Tstadm Vtnkbh strongly positively charged. And then produce X-rays and heat. 99% of the electricity used to appear on the body temperature is not helpful and only 1% of the energy converted to X-rays. Occurs Astdam electrons electrons metal atoms ousted by the elevator and outside the corn, because corn does not remain a long-free electrons, "between the electron vacancy from outside the corn and made this transition with X-ray beam of a specific wavelength.

And ceramics used today as the elevator and the place is covered by the collision of electrons Palmoulibdnom or copper or Baltnjstn.
[Edit] the seriousness of X-ray

X-rays belong to ionizing radiation. Any cause ionization in the middle, through which it and that the separation of some of the electrons in atoms and molecules. It can bring about changes in living cells may lead to the disease of cancer. Therefore governments to develop laws and instructions concerning the use of X-ray, whether in medicine or in industry, and monitors to follow those instructions and to punish violators of the laws in accordance with the instructions set out in this regard.

But X-rays are used also in the fight against cancer in a way to focus X-rays on cancer cells. The DNA of an organism is very sensitive to X-ray, as more and destroyed the increased absorption of UV rays. Any exposure to a small dose of radiation that no matter how small, is the possibility of turning one of the living cells to a cell cancerous. This is taken this possibility of cancer in mind when using X-ray in the diagnosis or treatment.

And generally should not be exposed pregnant women X-ray on the body, must also be very careful to use it on children, which may cause infertility in men and women have been if her reproductive organs.
[Edit] X-ray at the dentist

The dentist uses the X-ray imaging of teeth by the film and find out corrupt them to develop a plan for the restoration of teeth. However, processing the film takes a bit of time. In addition to the difficulty of storing and recording of those films. Therefore developed a method of imaging films and began to be replaced by digital photography by digital sensors. And you need that way the patient's exposure to less radiation during the imaging process. The picture shows directly on the screen chipset.

And take into account while taking X-ray images to protect other parts of the patient's body that do not fall into the examination of radiation by Hawwail ovoid. The nurse who works on the rays leave the room after the patient prepared to shoot, and you run the device from outside the room so as not to expose themselves to radiation. Usually held every nurse practical training every five years for a period of one day to renew their knowledge assets and the introduction of X-ray work new in this regard.
