X-rays: Advantages and Disadvantages

X-rays are electromagnetic radiations which have a wavelength shorter than ultraviolet rays but longer than gamma rays. Hard X-rays are commonly used to take an image (known as radiographic images) because they are able to penetrate solid objects like our bodies.


Advantages of x-rays: 

  • X-rays are used to treat malign tumors before its spreads throughout the human body.
  • They help radiologists identify cracks, infections, injury, and abnormal bones.
  • They also help in identifying bone cancer.
  • X-rays help in locating alien objects inside the bones or around them.   
Disadvantages of x-rays:
  • x-rays makes our blood cells to have  higher level of hydrogen peroxide which could cause cell damage.
  • a higher risk of getting cancer from X-rays.
  • The X-rays are able to change the base of the DNA causing a mutation.

Advantages
X-rays are used to treat malign tumors before its spreads throughout the human body. Those strong rays have the ability to destroy the excess cells that the body doesn’t need that eventually give the person cancer. X-ray guides robotic radio surgery for solid tumors; also more than 2,000 malign tumor carries have been treated with X-rays.
According the Radiological Society of North American (RSNA), bone X-rays have many advantages. They help radiologists identify cracks, infections, injury, and abnormal bones. They also help in identifying bone cancer. In addition, X-rays help in locating alien objects inside the bones or around them.

Disadvantages
People who frequently receive X-rays throughout their lives are at a higher risk of getting cancer from X-rays. The X-rays are able to change the base of the DNA causing a mutation. Mutations cause cancer because a single change in one of the triple bases will not let the DNA translate into RNA. For that reason the medical institutions tried to use a protective coat which was created to stop the X-rays. Although these coats have been determined as 100% scientifically safe, there is little research to prove their effectiveness.
