- 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
- Rayonnement ultraviolet - World Health Organization (WHO)
Qu’est-ce que le rayonnement ultraviolet ? Dans notre environnement, le soleil est de loin la source de rayonnement ultraviolet la plus importante Le soleil émet de la lumière, de la chaleur et des rayons ultraviolets (UV)
- 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
- 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
- Les effets connus des UV sur la santé
Les UV-A ont une longueur d’onde supérieure à celle des UV-B et pénètrent donc plus profondément dans les couches de l’œil et de la peau En outre, les UV-A dégagent moins d'énergie que les UV-B Les UV-A et les UV-B peuvent donc avoir des effets différents sur le plan biologique et de la santé Les UV-A pénètrent profondément dans la peau et peuvent atteindre le derme et l
- 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
- 紫外线辐射 - World Health Organization (WHO)
zi3wai4xian4fu3she4重要事实 皮肤癌主要由暴露于紫外线辐射所致。紫外线辐射来自太阳或日光浴床等人造日光源。 2020年，全球共检出150多万例皮肤癌，并报告了12万例以上皮肤癌死亡。 据估计，全世界共有1800万人因白内障而失明，其中约10%可能是因暴露于紫外线辐射。 儿童和青少年暴晒会导致今后患
