You can lead a life without fearing x-rays because the thought of shooting radiation is scary even though x-rays are safe. In this article, we will discuss how the x-ray machines work and understand x-rays. In 1895 x-rays were discovered during such time when a physicist was experimenting an electron beam in the tube for gas release. He performed this by lighting the beam so that that the fluorescent in the lab glowed. Fluorescents glow if they are put in front of electromagnetic radiation. When radiation was blocked by the cardboard that was surrounding the tube, the x-ray was discovered.
He went on to place many objects in front of the fluorescent screen and the tube to see what would block the radiation. He even put his hand before the tube and fluorescent, and here he saw his hand bones projected on the screen. 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. Xray can compare to visible light although the human eye cannot see the short wavelength. 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. This is the reason that though a human body we can see bones in an x-ray. 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 a cathode is charged negatively it becomes a filament that is heated through the current from the x-ray machines. The filament’s electrons come off to the surface.
Further, tungsten anode is charged positively attract the electrons through the tube. This is the process that forms ample energy to create an x-ray in a high energy photon form. Photons have thick lead however a small window allows escape through a narrow beam to the patient. Films are developed after the capturing of the x-ray patterns. A chemical reaction occurs and not a visible light.
You get to see the soft tissues through the x-ray. Contrast media is put in the body. Contract media is infused in the system making it easy for the absorption of x-ray. Upon swallowing barium, x-rays absorb the media which is infused in the body to make the body visible. Most cancers including lung cancer are normally detected using this process.
