Ultraviolet Index

Published on 13 Apr 2025

• Recently, Kerala observed higher variability of ultraviolet index (UVI).
• The UVI is a measure of the level of Ultraviolet Radiation and is an important vehicle to raise public awareness of the risks of excessive exposure to UV radiation and to alert people about the need to adopt protective measures.
• 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 less time it takes for harm to occur. 
• It was developed by the World Health Organisation (WHO), the United Nations Environment Programme (UNEP), the World Meteorological Organisation (WMO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
