  • Radiation: The ultraviolet (UV) index
    What is the UV index? a measure of the level of UV radiation; the values of the index range from zero upward - the higher the UVI, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur; an important vehicle to alert people about the need to use sun protection
  • Radiation: Ultraviolet (UV) radiation
    What is UV? Everyone is exposed to UV radiation from the sun and an increasing number of people are exposed to artificial sources used in industry, commerce and recreation The sun is by far the strongest source of ultraviolet radiation in our environment Solar emissions include visible light, heat and ultraviolet (UV) radiation
  • Ultraviolet radiation - World Health Organization (WHO)
    Ultraviolet (UV) radiation covers the wavelength range of 100–400 nm, which is a higher frequency and lower wavelength than visible light UV radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation
  • Ultraviolet radiation - World Health Organization (WHO)
    The Global Solar UV index (UVI), an information tool that describes the level of solar UVR at the Earth’s surface, was developed by WHO, the United Nations Environment Programme (UNEP), the World Meteorological Organization (WMO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP)
  • Raising awareness on ultraviolet radiation
    Raising awareness on ultraviolet radiation Small amounts of ultraviolet (UV) radiation are essential to produce vitamin D in people, yet overexposure to sunlight may result in acute and chronic health effects on the skin, eye and immune system
  • Radiation: The known health effects of ultraviolet radiation
    UV radiation can cause short- and long-term health effects on the skin In addition to the well-known short-term effects such as sunburn or allergic reactions, long-term effects like skin cancer represent a chronic health risk Skin cancer risk is strongly correlated with the duration and frequency of sun exposure over one’s lifetime Cumulative UV dose is related to the development of
  • Rayonnement ultraviolet - World Health Organization (WHO)
    Le rayonnement ultraviolet (UV) ne peut être ni vu ni ressenti Alors que certaines personnes sont exposées à des sources artificielles de rayonnement UV (par exemple en médecine, dans l’industrie et à des fins de désinfection et cosmétiques), tout le monde est exposé aux rayons UV solaires
  • Ultraviolet (UV) radiation - World Health Organization (WHO)
    One in every three cancers diagnosed is a skin cancer The main factor that predisposes to the development of skin cancer is exposure to ultraviolet (UV) radiation, traditionally from the sun and more recently from artificial tanning sunbeds Both solar radiation and sunbeds are classified as carcinogenic to humans by the WHO International Agency for Research on Cancer (IARC) Small amounts of
