X-rays are safe even if radiation shooting can sound scary however if you want peace of mind by understanding x-rays and be free of fears. In this article you will understand x-rays and how the machines work. 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. Fluorescents glow if they are put in front of electromagnetic radiation. The discovery of x-ray happened when the cardboard surrounding the tube did not prevent the radiation.
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. 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. 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 why through an x-ray we see 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 surface is filled with electrons from the filament.
Further, tungsten anode is charged positively attract the electrons through the tube. In this process ample energy is formed to create x-rays in form of form of high energy photon. Even if there is thick lead photon still escape through a small window and a narrow beam to the patient. This x-ray light pattern is received by a camera and films are developed. A chemical reaction occurs and not a visible light.
You get to see the soft tissues through the x-ray. This is done by putting contrast media in the body. Contract media is a liquid that better absorb x-rays than plain soft tissue. 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.
