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. Xrays were discovered in 1895 when a physicist was trying out electron beams in a gas release tube. The fluorescent in the lab glowed when the light in the beam was 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.
In his bid to know if there is any object that would block the radiation he continued placing many of them before the tube and the fluorescent. He even put his hand before the tube and fluorescent, and here he saw his hand bones projected on the screen. He discovered x-rays and its application in the medical field, so an x-ray is electronic radiation. It is similar with visible light, but the wavelength is short that human eyes cannot see it. This shortness of wavelengths show the high energy in x-rays.
these short wavelengths can go through many objects including the human body tissues. This is why through an x-ray we see bones through a human body. When a detector is placed on the other side, x-rays passing through the body assume a black shadow but anything like bones absorbed by the x-rays is white.
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 filament’s electrons come off to the surface.
Moreover, electrons are pulled through the tube after a tungsten anode which is positively charged. This process form enough energy to form an x-ray using a form of high energy photon. There is thick lead in photon but using a small window, but they escape using a narrow beam to the point to x-ray. This x-ray light pattern is received by a camera and films are developed. However a chemical reaction happens instead of a visible light.
It becomes possible to see soft tissues through the x-ray. The body is served with some contrast media. There is a liquid known as contract media which is injected so that there can be ease in x-ray absorption. Upon swallowing barium, x-rays absorb the media which is infused in the body to make the body visible. Lung cancers can be diagnosed using this procedure along with other types of cancer.
