Radiation is the release of energy from any source. Ultraviolet radiation is a form of electromagnetic radiation that comes primarily from the sun. High levels of ultraviolet radiation is carcinogenic to human body tissues. This raises the risk of developing cancer, especially breast cancer and melanoma (cancer of the skin), and a strong factor includes the amount of radiation that gets into the exposed area.
Too much ultraviolet radiation from the sun damages the genetic material (DNA) in the cells of the skin and beyond. If enough damage builds up with time, it will cause cells to start growing out of control leading to emerging cancer.
We cannot avoid sunlight completely for it is not healthy to do so because we fundamentally need vitamin D from the sun. So taking precautions like appropraite clothings that will protect our skin will limit uv radiation penetration. Also when outside, staying in a shade most especially during midday hours is one of the best ways to limit your ultraviolet radiation exposure from sunlight.
NB: Time of the day ultraviolet rays are strongest is between 10 am - 4 pm.
