A measure of the level of uv radiation 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 An important vehicle to alert people about the need to use sun protection.

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. Uv radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation. 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.
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A（UV-A）射线的波长比紫外线B（UV-B）射线更长，因此能够更深入地穿透眼睛和皮肤的组织层。UV-A和UV-B射线的能量强度也各不相同，UV-A射线的能量较低。因此，UV-A和UV-B引发的生物和健康影响存有差异。 UV-A可穿透皮肤深层，到达真皮和皮下组织，使结缔组织和血管受到影响，导致皮肤逐渐. 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)
Les uva, les uvb et les uvc 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.
