UV measurements
UV radiation levels vary substantially with time and place. The increased risk of UV damage to the skin and eye during a holiday in a sunny location is often underestimated.
The table below illustrates the changes in UV radiation levels with season and latitude. Maximal UV Index values are given for a range of cities in different countries, calculated for the 21st of each month.
