Very high erythemal doses of ultraviolet radiation around solar noon measured in Arica, northern Chile
In general, news media and meteorological bulletins report on the ultraviolet index (UVI) to prevent against overexposure to the sun. However, this information does not reflect the accumulated damage to the skin induced by the total amount of UVR accumulated over time, known as erythemal dose (ED). This study analyzed the UVI and ED measured at 30 and 60 minutes around solar noon (SN) in Arica, North of Chile. The results show that SN ED exceeded the Minimum Erythema Dose (MED) for all the skin types. During the summer, short exposures to sunlight for up to 1 hour may result in sun exposure up to 10 times greater than the acceptable occupational safe limit for unprotected human skin.
期刊介绍：
ATMÓSFERA seeks contributions on theoretical, basic, empirical and applied research in all the areas of atmospheric sciences, with emphasis on meteorology, climatology, aeronomy, physics, chemistry, and aerobiology. Interdisciplinary contributions are also accepted; especially those related with oceanography, hydrology, climate variability and change, ecology, forestry, glaciology, agriculture, environmental pollution, and other topics related to economy and society as they are affected by atmospheric hazards.
