title: [Effect of UV index in the skin exposure].
abstract: This research was conducted from October 2003 to March 2005, collecting data through the measuring authorized volunteers measuring their photoexposition . It worked with the equipment (Safesun from Optix Tech, Inc.), available for measuring. The radiation impact of solar on the city of Cordoba, was chosen measurements for a clear spot on the terrace of the Observatory Environmental Laprida located at 854, in a position that excedes level approximately 30 meters from Piazza San Martin (centerhistoric city). It had two fixed radiation sensors total solar and ultraviolet A radiation sensor manual ultraviolet calibrated according to the erythemal response of skin measuring human ultraviolet index and the maximum exposure timer ecommended for different skin types (Safesun from Optix Tech, Inc.).The aim of this study was to measure the rate and exposure ultraviolet (UV) to evaluate the erythemal effect on most sensitive areas of the face and neck to noon fotoexposición solar in the four annual seasons, and thus promote extending protection regulations to prevent the effects harmful UV non-ionizing radiation. The analysis of the data, UV index values indicate that from the Winter season is observed to undergo the risk of exposure excessive radiation at noon solar day is measured with high Fall UV index is high in spring and high-very high and with days end in the Summer season daily with UV index very high and extreme. This risk remains in the four annual seasons and according to the criteria of the World Health Organization is need to perform significant work to develop measures, education campaigns and outreach, which tend to diminish the sun exposure, hours with the highest incidence of lightning ultraviolet in the four annual seasons. The global environmental degradation and thus destruction of the ozone layer, has been a direct cause of the increase in ultraviolet radiation on earth, which resulted increased rates of cancer incidence and prevalence skin, within the population.
