Ultra-violet radiation of very short wavelengths can be very harmful to the skin, and are responsible for causing our sunburns. Tanning and natural body pigments prevent the destruction of skin cells by ultraviolet light to a certain extent. But prolonged exposure can cause skin cancer, cataract and damage to the human immune system. However, we are protected from the large amounts that the Sun releases by the layer of Ozone gas in the atmosphere, which absorbs a major part of the small-wavelength rays. A small dose of UV rays is though beneficial to the human body, and can be used to treat some skin deseases as they can kill some harmful bacteria. Scientists today, have developed a UV index to help people protect themselves from these harmful ultraviolet waves.
