Solar radiation is an important natural factor in the life of the Earth. The ultraviolet part of the solar spectrum, more commonly know as UV radiation, plays an important role in many processes in the biosphere but it could be very harmful if its quantity exceeds safe limits. To avoid damage from high UV exposures the human being should limit their exposures to solar radiation. Solar UV radiation is a highly variable environmental parameter that changes widely in time and space. Using the results of worldwide meteorological observation, measurements and forecasting techniques, a simple-to-understand parameter has been developed. The UV Index (UVI) is now widely used in many operational weather reports and forecasts. Different methods are used to predict the UVI. To coordinate these activities and improve their scientific background a COST Action; titled "UV-B Forecasting" was initiated in 1996. This booklet/brochure facing the UV problems and its physical and biological background help the understanding of UVI forecasts and promote protection activities against harmful radiation.
