Although x-rays are safe, shooting radiation sound scare but if you want to be at peace, you can x-ray and lead an x-ray fear free life. This article seeks to discuss x-rays and how their machines works. Electron beams were being released in a gas tube and during that time x-rays were now discovered by a physicist in 1895. He did this by the light the beam, and the fluorescent in the lab lit. Normally there is a glow in fluorescents in case they are put before electromagnetic radiation. The discovery of x-ray happened when the cardboard surrounding the tube did not prevent the radiation.
He continued placing several objects before the fluorescent screen and tube to find out if any of them would prevent the radiation. The bones of his hand were projected when he put his hand before the fluorescent and the tube. Xray was discovered at this point, and he also discovered that it has benefits to the medical front so we can comfortably define x-ray as electronic radiation. Even though the wavelength is short x-ray can compare to visible light only that the human eye cannot see it. This shortness of wavelengths show the high energy in x-rays.
It means that this wavelength can pass through the human body and other objects. No wonder in an x-ray we see the bones through a human body. After placing a detector on the other side, when x-rays pass through a body a black shadow is seen however there is a white appearance of anything that absorbs the x-rays such as bones.
In the vacuum glass tube, there is an electrode pair at the middle of the x-ray machine. If there is negative charging of a cathode there is a heated filament that is through the x-ray machines current. The electrons come off from the surface of the filament.
Further, tungsten anode is charged positively attract the electrons through the tube. This process form enough energy to form an x-ray using a form of high energy photon. Photons have thick lead however a small window allows escape through a narrow beam to the patient. This pattern of x-ray is captured by the camera and films are developed. However a chemical reaction happens instead of a visible light.
You get to see the soft tissues through the x-ray. The body is served with some contrast media. Contract media is a liquid that better absorb x-rays than plain soft tissue. Upon swallowing barium, x-rays absorb the media which is infused in the body to make the body visible. Lung cancer is easily diagnosed through this process as well as other cancer types.
