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 a form of electromagnetic energy that lies between visible light and X-rays. It has various effects on the human body, such as sunburn, tanning, aging, and cancer, and can be used for sterilization, fluorescence, and vitamin D production.
10 de ago. de 2016 · Learn about ultraviolet (UV) light, its sources, effects, and applications in astronomy and Earth sciences. See images of UV waves from the Sun, stars, galaxies, and aurorae.
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 · Learn about the different types of UV radiation, how they affect the skin and eyes, and what factors influence your exposure. Find out how ozone depletion, season, time of day, altitude, clouds, and reflection affect UV levels.
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.
