Solar ultraviolet radiation (UVR) from the sun is now understood to have both positive and detrimental impacts on people and other living things. Changes in human behavior, such as increased participation in outdoor activities, raise the risk of UV exposure. Some of skin diseases are caused by UVR exposure. In this paper, the time in minutes at which skin burns occur each day for the year 2021 was calculated based on the area of skin exposed to solar radiation for all skin types (according to the classification of Fitzpatrick) in the case of applying sunscreen or without it in the clear sky conditions of the cities of Mosul, Baghdad and Basra at Latitudes (878, 7676, 8878), respectively. UV index data was obtained by TEMIS platform. An increased risk of sunburn was observed with an increase in the UVI index during the summer for all regions, especially the city of Basra, which showed an increase in the number of extreme days of the UVI index over the course of a year, there are 111 days extreme compared to the rest of the regions, and from that we conclude that there is a short period of time for the onset of burns when the UVI index is high, and its effect on different skin types, especially on with light skin, and an increase in the time period for the onset of burns when using sunscreens
