Seasonal variation of UV radiation at the Dead Sea.

Pilot measurements were made of natural UV radiation (UVA and UVB, broad-band and erythemogenic) on the Dead Sea (400 m below sea level) and in Spain at sea level, both at approximately the same geographical latitude. Measurements were made at different times of single days during the 1985/1986 season. The preponderance of UVA over UVB was more pronounced in winter.
