Explanation :
An x-ray technician will place a lead cloth over parts of your body when taking an x-ray to protect your cells from being damaged. This is due to the reason that x-rays have the potential to harm our body.
X-rays have shorter wavelength while radio waves have a longer wavelength. Also, the frequency of x-rays are more and the radio wave is less.
Since energy is directly proportional to frequency, so x-rays carry more energy which transferred to our body.
When the human body is directly exposed under x -rays, the electrons of x-rays strikes and due to this our DNA chains can break. This can leads to cancer.
