ABSTRACT
Background: Ultraviolet radiation is present in sunlight. If ultraviolet radiation exceeds the limit, it can cause detrimental effects on human health such as skin cancer and cataract
Materials and Methods: In this descriptive cross-sectional study, the level of solar ultraviolet radiation type A [UVA] were measured using UV LOG HAND HELD in Kermanshah city. The intensity of ultraviolet radiation was measured three times a day including two hours before noon, noon and two o'clock in the afternoon. The results were analyzed using ANOVA statistical tests with a confidence interval of 95%
Results: The lowest and highest average intensity levels of solar UVA in Kermanshah were in December [14.21+/- 0.94 w/m2] and August [32.87 +/-2.3 w/m2], respectively. Also, winter and summer seasons (with average intensities of 16.37+/- 1.12 w/m2 and 30.12+/-1.7 w/m2] had the lowest and highest intensity of this radiation, respectively
Conclusion: Regarding that UVA radiation exceeds the safe exposure level, even in the winter in Kermanshah, it is recommended for people to avoid from long-term staying in open spaces at noon and use proper protective wears especially in summer?
