But when feet feel cold but are not cold to the touch, a possible cause is a neurologic problem, such as peripheral neuropathy. Of course, feet can get cold for many reasons. The most obvious is a cold environment, along with a lack of proper shoes or socks.
X-RAY PHOTON. A brief definition of an x-ray photon was previously stated. However, a more comprehensive definition is necessary for the next series of photon actions. X-ray photons are electromagnetic rays produced in the x-ray tube head when electrons from the cathode filament strike the anode target. They are bundles of pure energy. The photons transfer their energy to the substance through which they pass whether it be air, an x-ray film, or the living tissue of the patient or the specialist. They cannot be seen or felt. a. Photon Action Upon Atoms. (1) Photon collision with the nucleus of an atom. The photon may strike the nucleus of an atom.
An x-ray is a form of electro magnetic radiation, with a wavelength of 10 to 0.001 nanometers (shorter than ultraviolet light).The letter 'X' comes from their initial discovery, when they were an unknown form of radiation and thus given the moniker 'X' to indicate 'unknown.'.he patient is positioned between the x-ray machine and the film. It is the x ray technician's job to properly align the patient in space in order to capture the appropriate 2-D plane. Areas not of interest should be appropriately shielded. After the beam is activated, the film is shown to the radiologist.
