Ultraviolet radiation and the INTERSUN Programme

The UV Index

What is the UV index?

  • The UVI is a measure of the level of UV radiation.
  • The values of the index range from zero upward - the higher the UVI, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur.
  • The UVI is an important vehicle to alert people about the need to use sun protection.
