x-ray

          X-rays are electromagnetic radiation 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.


          Clearly, The disadvantages  are more than the advantages. In my opinion its the most horrible invention ever. Have a lock to some of the negative things that x ray may cause:
1-Makes the blood cells have a higher level of hydrogen peroxide which could cause cell damage.
2- A higher risk of getting cancer.
3-Its able to change the base of the DNA causing a mutation.
