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. If electromagnetic radiation comes close to fluorescents they glow. It was here that x-ray was discovered when the surrounding cardboard on the tube blocked the radiation.
He continued placing several objects before the fluorescent screen and tube to find out if any of them would prevent the radiation. 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. Xray can compare to visible light although the human eye cannot see the short wavelength. The short wavelengths confirm that x-ray has high energy.
It means that these wavelengths 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.
At the center of an x-ray machine is a pair of an electrode in the vacuum glass tube. If a cathode is charged negatively it becomes a filament that is heated through the current from the x-ray machines. The electrons come off from the surface of the filament.
Moreover, electrons are pulled through the tube after a tungsten anode which is positively charged. In this process ample energy is formed to create x-rays in form of 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. But this time instead of a visible light there is a chemical reaction.
From the x-ray you can see soft tissues. Contrast media is put in the body. Contract media is infused in the system making it easy for the absorption of x-ray. The body becomes visible after media is injected so that x-rays can absorb it after barium is swallowed. Lung cancer is easily diagnosed through this process as well as other cancer types.
