An increasingly worrying phenomenon is the hole in the ozone layer, and contrary to popular belief, not just a southern problem. The values of UV radiation does not change according to latitude.
Contrary to popular belief, and spread with such alarm in October, at any point south of the country is more exposed to ultraviolet radiation (UV) than the rest of the country, although certain areas have been this year up to ten days under the ozone hole.
The day in Ushuaia was the minimum ozone value was similar to what was recorded in January and this time south of Corrientes, Córdoba and Mendoza had equal records.
The decrease in the ozone layer has increased the intensity of ultraviolet radiation (UV), which also is stronger in summer.
Excessive sun exposure can cause short term, redness and skin burns, eye discomfort and allergic reactions, while long-term and the effect of accumulation is the threat of skin cancer.
The UV radiation breaks the bonds of DNA molecules and alter the genetic information. Although they are essential for life, if not filtered by the ozone before falling on the surface are proven harmful.
To find out how long it takes UV radiation eventually cause redness and burning, depending on skin type, there is the risk map plot, which graphs the current national rate of solar ultraviolet (ISUV) and indicates the risk of overexposure to the sun.
The Argentine ISUV, unlike international ranges from zero to 16, reaches 28, it incorporates a variable height. Forecast is not the same amount of ultraviolet radiation for a given latitude at sea level to 3000 feet.
