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. 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 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 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. 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.
these short wavelengths can go through many objects including the human body tissues. 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 surface is filled with electrons from the filament.
On the other hand, the tungsten anode that is positively charged pull the electrons across the tube. This process form enough energy to form an x-ray using a 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. However a chemical reaction happens instead of a visible light.
It becomes possible to see 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. Lung cancers can be diagnosed using this procedure along with other types of cancer.
