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. Uv radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation. Key facts skin cancers are caused primarily by exposure to ultraviolet radiation (uvr), either from the sun or from artificial sources such as sunbeds Worldwide, it is estimated that 15 million people are blind due to cataracts Of these, some 10% may be due to.
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. 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. 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. 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
Global burden of disease from solar ultraviolet radiation human exposure to solar ultraviolet radiation has important public health implications Evidence of harm associated with overexposure to uv has been demonstrated. Les uv peuvent avoir des effets à court et à long terme sur la peau En plus des effets à court terme bien connus, tels que les coups de soleil ou les réactions allergiques, les effets à long terme comme le cancer de la peau représentent un risque chronique pour la santé Le risque de cancer de la peau est fortement corrélé à la durée et à la fréquence de l’exposition au soleil. Resumen la radiación ultravioleta no puede verse ni sentirse
Aunque algunas personas están expuestas a fuentes artificiales de esta radiación (por ejemplo, en la medicina, la industria, para la desinfección o con fines cosméticos), todos estamos expuestos a la radiación ultravioleta solar Los niveles de esta radiación dependen de varios factores
