What is meant by UV radiation?
Ultraviolet radiation is electromagnetic radiation or light having a wavelength greater than 100 nm but less than 400 nm. It is also known as UV radiation, ultraviolet light, or simply UV. Ultraviolet radiation has a wavelength longer than that of x-rays but shorter than that of visible light.
What is UV radiation used for?
UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning. Different UV wavelengths and intensities are used for different purposes.
What causes UV radiation?
Exposure to UV radiation is the main factor that causes skin cells to become cancer cells. Almost all skin cancers (approximately 99% of non-melanoma skin cancers and 95% of melanoma) are caused by too much UV radiation from the sun or other sources such as solaria (solariums, sunbeds, and sun lamps).
What is the difference between UVA and UVB and UVC?
While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB. Like all forms of light on the EM spectrum, UV radiation is classified by wavelength.
What is the full form of UV rays?
Medical Definition of UV radiation
UV radiation: Ultraviolet radiation. Invisible rays that are part of the energy that comes from the sun, can burn the skin, and cause skin cancer. UV radiation is made up of three types of rays — ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC).
What materials can block UV rays?
Construction: Like color, the material, weave and texture of your clothing can affect how well it protects you from UV rays. Synthetic and semisynthetic fibers like polyester or rayon are the best choices for sun protection, as are dense, heavy, tightly woven fabrics like wool, denim or corduroy.
