X-rays are often worked as electromagnetic radiation. It is the ray that is characterized by protons particles and is an alternative name of radiography. These rays are allowed to pass through an object o body part, and the result is printed on a thin film. However, there are a number of uses and drawbacks of X-rays. There are a number of benefits of x-rays. It is used in hospitals and clinics to check the bone structure of a person as well as procuring of dental damage. There are a number of fields and companies that use x-rays to examine enclosed packages. These rays are able to reveal the structural abnormalities that are difficult to detect by naked eyes. Usually, x-rays are used in highly secured and confidential areas. Based on the data report provided by x-ray diffraction center, the rays can detect guns, knives, bombs and other deadly weapons. Not only this, they are programmed in such a way that they identify the entry and exit of unauthorized person or object.
What is X-ray diffraction?
According to Braggs' theory of diffraction, when the electrons moving at high speeds are directed to a metal target, a small percentage of it is converted into kinetic energy. The x-rays emitted by targets consist of continuous wavelengths. The minimum wavelength is inversely proportional to applied voltage and accelerates the electrons towards the target. The radiation emitted by specific wavelength is emitted by the target.
The electrons oscillate under the impact and become a new source of electromagnetic radiation. The emission is in all the directions and depends highly on the direction of the incident rays. In other directions, the destructive interference from different sources is formed. The easy method to visualize the diffraction effects is considered as Bragg law. There is an equivalent description of diffraction effects produced by 3-dimensional grating.
Uses and risks associated with x-rays
X-rays can be used to determine surgical results and improving treatments. They are beneficial in verifying surgery results and can be used to reveal abnormalities in the body. X-rays can be used to detect risk of cancer and the chances of developing heart disease. According to medical experts, the radiation produced by x-rays is very dangerous and cause harm to the cells of the body. Thus, doctors should limit the scanning procedures to reduce the risk of chronic diseases. Constant exposure to x-rays may even cause harm to the heart and ruptures the blood vessels.
Another risk associated with x-rays is that they cause birth defect in children. That is the reason why pregnant women are usually not asked to go through x-ray scanning in airports and other public places. These are some dangers of x-rays and when you are about to go through x-ray test, make sure that the procedures are done correctly. Make sure to consult your doctor before you go through x-ray test. By following some tips, one can stay away from the risk of x-rays. One should always maintain a significant distance from the aperture of x-ray machine to avoid health problems.
