Very high erythemal doses of ultraviolet radiation around solar noon measured in Arica, northern Chile

News media and meteorological bulletins generally report on the ultraviolet index (UVI) to prevent overexposure sun. However, this information does not reflect accumulated damage skin induced by total amount of UVR (ultraviolet radiation) over time, known as erythemal dose (ED). This study analyzed UVI ED measured at ±30 ±60 minutes around solar noon (SN) in Arica, North Chile. The results show that SN exceeded Minimum Erythema Dose (MED) for all types. During summer, shorts exposures sunlight up 1 hour may result sun exposure 10 times greater than acceptable occupational safe limit unprotected human skin.
