- Radiation: Ultraviolet (UV) radiation - World Health Organization (WHO)
The sun is by far the strongest source of ultraviolet radiation in our environment Solar emissions include visible light, heat and ultraviolet (UV) radiation Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC
- Ultraviolet radiation - World Health Organization (WHO)
Ultraviolet radiation (UVR) can neither be seen nor felt While some people are exposed to artificial UVR sources (e g in medicine, industry and for disinfection and cosmetic purposes), everyone is exposed to solar UVR Solar UVR levels are influenced by several factors: Sun elevation: the higher the sun in the sky, the higher the UVR level
- 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
- Raising awareness on ultraviolet radiation - World Health Organization . . .
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 The rise in the incidence of skin cancers over the past decades is strongly related to increasingly popular outdoor activities and recreational exposure Experts believe that 4 out of 5 cases of
- Radiation: The known health effects of ultraviolet radiation
Current scientific evidence suggests that different forms of eye cancer may be associated with UV exposure Uveal melanoma, the most frequent cancer of the eyeball, sometimes requires surgical removal and is associated with high mortality Evidence of an association with ultraviolet exposure is mixed
- Radiation: The ultraviolet (UV) index - World Health Organization (WHO)
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
- 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
