- X-rays similar to X-ray visible light photons Both have a component of a moving carrier wavelength electromagnetic energy electromagnetic energy, but the difference between X-ray and visible light rays is the energy level of photons, which is expressed in wavelength radiation wavelength.
- The human eye is sensitive to a particular area of the range within which wave lengths of visible radiation, but they are sensitive to X-ray, which cut into the length of less than visible light and thus energy is higher, and it is not sensitive to radio waves radio waves that have the largest wavelength of visible light and thus less energy.
- The X-ray photons as photons of visible light produced by the movement of electrons in atoms, where electrons occupy these Suiat hat different orbits around the nucleus of an atom, and when moving electron from its orbit to orbit together with a lower cap it frees energy in the form of photons, depends Energy these photons on the difference between Suetin Takitin the first and second electron.
Shocked when the photon point the other atom of this atom absorbs the photon energy through the transfer of electron to the cap along the top. For this to happen must be normal to the photon energy is equal to the difference between the Suetin Takitin of the electron.

Typically, you weave rights atoms absorb photons of various visible light, as the Sueat energy photons of visible light to suit the differences between the different positions of electrons in atoms tissues. While radio waves do not have sufficient energy to transfer electrons between different Sueat energy of atoms, and thus is able to penetrate different objects, as well as also the case in X-rays, but the only difference is that X-rays have very high energy.
X-ray when you can fall on the relatively small atoms to expel the electron atoms, where some X-ray photon energy separation of the electron atom, while the residual energy to pay the electron away from the atom is often unable to absorb photons of X-rays. While the atoms are relatively large X-ray photon absorption, because these atoms have the differences between the high-hat orbits and these differences are roughly equal to the energy X-ray photons.
Diverse tissues in the human body is either made up of small particles and therefore unable to absorb photons of x-ray, may be significant Kdhirat calcium calcium atoms that constitute the infrastructure of the bones and thus is able to absorb photons of X-rays.

Principle simplified X-ray machine in general:

While the positively charged anode elevator is a flat disk of tungsten tungsten.
Applied voltage difference between the lift and runway intended to give the electrons extracted from the runway at high speed toward the elevator, when the shock electron tungsten atom located on the elevator releases the electron together with a low cap of this corn, and replace the electron electron of the same corn, but enjoy doing, cap the top, this process will result in excess free energy in the form of a photon doing, high-hat, is the X-ray photon.

And also can generate free electrons, photons, without the shock of atoms, where the nuclei of atoms to attract electrons accelerated, where a slowing of the electrons, and change tracks, and thus make the electron at this situation of excess capacity in the form of photons of the X-ray.
