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.
May 31, 2024 · Ultraviolet radiation is a form of electromagnetic energy that lies between visible light and X-rays. It has various applications, such as producing vitamin D, sterilizing materials, and fluorescing substances, but it can also cause skin damage and cancer.

Ultraviolet (UV) radiation is a form of energy that the sun produces. You can’t see UV radiation because its wavelengths are shorter than visible light. The UV energy that the sun produces reaches the Earth and provides vitamin D for your body to help you survive. You can also find UV radiation in human-made sources like tanning beds. Exposure to t...
Exposure to the sun causes changes to your skin. While many people think that a glowing complexion means good health, changes to your skin tone from being in the sun can speed up the effects of aging and increase your risk of developing: 1. Skin cancer. 2. Wrinkles. 3. Freckles. 4. Liver spots. Over time, the sun’s ultraviolet light damages the fib...
Too much ultraviolet radiation causes skin cancer. Your body needs some UV light for vitamin D, which is a vitamin you need to survive. When your skin has too much exposure to UV radiation, it damages your cells. Within your cells, you have DNA. DNA tells your cells how to form and function within your body. Too much UV radiation targets the DNA in...
Learn how ultraviolet (UV) radiation from the sun or tanning beds can cause skin cancer and other skin problems. Find out how to prevent and treat skin cancer and protect your skin from UV exposure.
Feb 15, 2024 · Learn about the benefits and risks of UV radiation from the sun and artificial sources, such as tanning beds. Find out how to protect yourself and others from overexposure, skin cancer, and eye diseases.
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.
