The full form of UV is Ultraviolet.
Understanding Ultraviolet (UV) Radiation
Ultraviolet (UV) radiation is a type of electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays. The wavelength ranges from 10 to 400 nanometers (nm). [^1, ^5] Sunlight is a significant source of UV radiation, making up approximately 10% of the sun's total electromagnetic radiation output. [^1, ^6] Other sources include electric arcs. [^6]
UV radiation is further categorized into three types: UVA, UVB, and UVC. All three types can harm the skin, although they have different effects and penetration depths. [^4] The UV Index (UVI) is a scale used to measure the intensity of UV radiation reaching the Earth's surface. The UVI ranges from 0 upwards, with higher values indicating a greater risk of sun damage. [^2, ^3, ^7, ^8]
The UVI is an important factor for determining the level of protection needed against harmful UV rays. Factors such as ozone levels and time of day can affect the daily UVI forecast. [^7] Exposure to UV radiation can lead to sunburn, premature aging, and an increased risk of skin cancer. [^4, ^8] Several studies have investigated the effects of UV radiation exposure and its impact on various health aspects. [^9]
[^1]: What is the full form of UV? The full form of UV is Ultraviolet. UV light has a wavelength of 10 to 400 nm, which is shorter than the visible light but longer than the X-rays and is a form of electromagnetic radiation. They are found in sunlight and produce 10 per cent of the light from the total sunlight.
