- Radiation: Ultraviolet (UV) radiation
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 (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)
Key facts Skin cancers are caused primarily by exposure to ultraviolet radiation (UVR), either from the sun or from artificial sources such as sunbeds Globally in 2020, over 1 5 million cases of skin cancers were diagnosed and over 120 000 skin cancer-associated deaths were reported Worldwide, it is estimated that 15 million people are blind due to cataracts; of these, some 10% may be due to
- 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 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
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
- 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
- Global solar UV index - a practical guide
The Global Solar UV Index (UVI) described in this document is a simple measure of the UV radiation level at the Earth’s surface and an indicator of the potential for skin damage It serves as an important vehicle to raise public awareness and to alert people about the need to adopt protective measures when exposed to UV radiation
- 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
