Definition Of X Ray Photon
This is known as attenuation the attenuation theory is valid for x rays and gamma rays as well.
Definition of x ray photon. γ a quantum of electromagnetic radiation the photon can be considered as an elementary particle with zero rest mass charge and spin traveling at the speed of light a beam of electromagnetic radiation can thus be thought of as a beam of photons with the intensity of the radiation proportional to the number of photons present. The higher energy photons are less likely to. Like all elementary particles photons are currently best explained by quantum mechanics and. An uncharged particle of energy moving in waves produced by the interaction of high speed electrons with a target commonly tungsten.
The elementary particle of light and other electromagnetic radiation. However a more comprehensive definition is necessary for the next series of photon actions. These particles vary from those of lower energy 1 to 0 1 a u used in diagnostic imaging to those of higher energy 0 1 to 10 4 a u used in therapy. A brief definition of an x ray photon was previously stated.
At this energy the penetration through 1 cm of tissue is 0 45 and the penetration through 15 cm of tissue is. They are bundles of pure energy. X ray photons are electromagnetic rays produced in the x ray tube head when electrons from the cathode filament strike the anode target. It turns out that higher energy photons hard x rays travel through tissue more easily than low energy photons i e.
X ray photon synonyms x ray photon pronunciation x ray photon translation english dictionary definition of x ray photon. A photon is the smallest discrete amount or quantum of electromagnetic radiation. Photons are always in motion and in a vacuum travel at a constant. The photon is a type of elementary particle it is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves and the force carrier for the electromagnetic force photons are massless so they always move at the speed of light in vacuum 299 792 458 m s.
It is the basic unit of all light. Total photon cross sections. As photon energy increases to about 40 kev penetration increases but much more gradually. An x ray or x radiation is a penetrating form of high energy electromagnetic radiation most x rays have a wavelength ranging from 10 picometers to 10 nanometers corresponding to frequencies in the range 30 petahertz to 30 exahertz 3 10 16 hz to 3 10 19 hz and energies in the range 124 ev to 124 kev x ray wavelengths are shorter than those of uv rays and typically longer than those of.
Look it up now. Photon foh ton symbol. Of special interest is the very low penetrating ability of x ray photons with energies below approximately 20 kev.
