Answer 2

We are exposed to UV rays throughout our lifetime because

• Everyone is exposed to UV radiation from the sun and a more number of people are exposed to artificial origins which are used in industry, labour and leisure.
• The sun is by a distance the most powerful source of ultraviolet radiation in our atmosphere.
• Solar emissions comprise visible flash, heat and ultraviolet (UV) radiation.
• Just as visible light comprises various colours that evolve evident in a rainbow, the UV radiation expanse is split into three major regions known as UVA, UVB and UVC.
• As sunlight passes through the environment, all UVC and most UVB is consumed by ozone, water vapour, oxygen and carbon dioxide. UVA is not seeped as considerably by the atmosphere.
