Abstract

Aims this study is focused to calculate exposure times which cause to skin damage (one minimum erythemal dose) and the optimal time for exposure to sunlight that is needed to receive adequate UV for vitamin D production, without inducing erythema at Baghdad city. In this study calculated the annual and seasonal optimal time for exposure of Ultraviolet radiation and Maximum exposure time for causes skin burns in Baghdad depending on the Fitzberk classifcation assuming normal ozone conditions throughout the year by using Ultraviolet radiation data received from French site for Solar radiation data(SODA) in the period 1/1/2005 to 31/12/2017. The greatest time for exposure to solar radiation to create vitamin D without skin burns was 16 min in winter, 6 min in spring, 5 min in summer and 9 min in autumn, While the greatest exposure time to solar radiation that causes burns is 80 min in winter, 32 min in spring, 22 min in summer, and 46min in autumn. It was fnd the number of days per UV Index level was found in one year (2015) were low level 8 days, Medium level 74 days, High level 68 days, Very High level 93 days.
