Tungsten Alloy Shielding Application in X-ray MachineⅠ

X-ray machine is a device to generate X-rays, and mainly to be used in the medical field for diagnosis, chest X-ray, gastrointestinal diseases checking and so on. X-rays were discovered by German physicist called Wilhelm Röntgen, on the whole, X-rays are the same thing with the visible light. There are three ways to generate X-rays: bremsstrahlung, electron capture and internal conversion. The greater radiation would be caused by X-ray machine, over time, it will cause inevitable damage in humans’ bodies and even lead to cancer. However, if installed with tungsten alloy shielding in X-ray machines, it may be greatly shield the radiation, and weakened the X-ray radiation intensity.
 
X-ray machine is mainly composed of X-ray tube, X-ray machine power, control circuits and other components, and the X-ray tube is composed of the cathode filament, the anode target and a vacuum glass tube. The core of X-ray machine is the cathode filament and the anode target, they locate in the same vacuum glass tube. The machine can transport the current through the cathode filament and then the filament will be heated , after that, the heat will sputter out the electron of filament surface. As can be seen from the following diagram of X-ray machine working illustration, in addition to the vacuum tube, the cathode filament and the anode target, it is also composed of oil grooves, the shielding, engines and filtration device. The anode of X-ray machine is a  roulette, which is made of tungsten, can absorb the electron over from the vacuum tubes. The rotating engine, next to the anode, is mainly used to prevent the melting problem caused by the high heat of violent crashing in the X-ray generation process. The vacuum tube surrounding the cooling oil can also absorb some heats.
