El ultravioleta (UV) es una forma de radiación electromagnética con una longitud de onda más corta que la de la luz visible, pero más larga que la de los rayos X.
Ultraviolet ( UV) light is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
31 de may. de 2024 · Ultraviolet radiation is the portion of the electromagnetic spectrum extending from the violet, or short-wavelength, end of the visible light range to the X-ray region. How is ultraviolet radiation produced?
10 de ago. de 2016 · UV-B rays are the harmful rays that cause sunburn. Exposure to UV-B rays increases the risk of DNA and other cellular damage in living organisms. Fortunately, about 95 percent UV-B rays are absorbed by ozone in the Earth's atmosphere.
Los efectos agudos de la radiación ultravioleta pueden ser: daños en el ADN, quemaduras solares, reacciones fototóxicas y fotoalérgicas e inmunodepresión, que puede considerarse un factor de riesgo de cáncer y dar lugar a la reactivación de virus (por ejemplo, el del herpes labial).
9 de mar. de 2016 · 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.
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.
