UV Index as a guide for sun protection measures. The UV Index scale is divided into different areas, for which different protection recommendations apply. The UV Index is therefore not only a measure of the expected UV exposure, but gives also recommendations as to what sun protection measures should be taken at what UV Index values.

UV-index i Sverige. Det svenska UV-indexet är framtaget av SMHI på uppdrag av Strålsäkerhetsmyndigheten SSM, enligt internationella rekommendationer från bland annat WHO (World Health Organization) och WMO (World Meteorological Organization). Under sommaren är UV-index i Sverige vanligen 4-7 och under den mörka årstiden (nov-feb) under 2.

The World Health Organization's Global Solar UV Index measures UV levels on a scale from 0 (Low) to 11+ (Extreme). Sun protection is recommended when UV levels are 3 (Moderate) or higher. The UV level is affected by a number of factors including the time of day, time of year, cloud cover, altitude, location and surrounding surfaces. We must however be careful to ensure that a species is not able to obtain access to a higher UV Index than the highest level shown in this guide. For more information please do read the information given on the front page of the ‘lighting guide’. All measurements have been taken with a Solarmeter 6.5 ‘Index Meter’.

Don't forget: in winter, reflection off snow can nearly double UV strength. 3 to 5: Moderate (yellow) Stay in the shade during late morning through mid-afternoon. UV Index: The Sun Safety Scale. The UV Index scale is a great tool to tell you how quickly sunburn can occur if you are not applying proper protection. The ultraviolet levels are measured on a daily basis by the National Weather Service and then are converted to a scale of exposure risks.

Some people might not know about the potential risks or how the index scale is rated. There is a scale The UV Index was developed to help Canadians protect themselves from the sun’s damaging UV (ultraviolet) rays.

Uv index scale

UV can cause sunburn, eye cataracts, skin aging and skin cancer. 2019-03-29 · When the UV Index scale was invented, tests were done on human skin at each UV wavelength to see the effects. Scientists found that shorter wavelengths were more dangerous (shorter wavelengths have more energy). Every day the UV Index is calculated for the next day for every zip code in the U.S. It predicts the intensity of UV radiation at noon and is reported on a scale of 1 to 11+.

It might even be higher in the tropics and/or at high elevations under clear skies. The UV Index does not exceed 8 in the UK (8 is rare; 7 may occur on exceptional days, mostly in the two weeks around the summer solstice). However, indices of 9 and 10 are common in the Mediterranean area. The strength of the sun's ultraviolet (UV) radiation is expressed as a Solar UV Index or Sun Index.The UV Index does not exceed 8 in the UK (8 is rare; 7 may occur on exceptional days, mostly in the two weeks around the summer solstice).
