紫外线波段和各种紫外波段的紫外灯用 Uvb refers to light with wavelengths between 280 nm and 315 nm. while fewer of these rays penetrate the earth’s ozone layer, those that do are more intense than uva light. because of this, uvb light is often cited as the source that causes sunburn. in fact, uvb rays can burn the top layer of your skin, known as the epidermis layer, in as. Ultraviolet light is subdivided into uv a (315 to 400 nm), uv b (280 315 nm), and uv c (100 280 nm). artificial uv used for disinfection is almost always uv c, so uv and uvc are often used.
The Abc S Of Ultraviolet Radiation At the same uv light intensity it takes to kill 99.9% of sars cov 2 in 20 seconds, a person could be safely exposed to 222 nanometer light for up to one hour and 20 minutes. Hands down, unprotected exposure to the sun’s uv rays is the no. 1 source of damage to your skin and eyes, but tanning beds are a close second. indoor tanning may cause as many 400,000 cases of skin cancer in the u.s. each year, according to the american academy of dermatology (aad). (believing that a tanning bed is safer than the sun is. Uvc is the shortest wavelength of the three forms of uv. the shorter the wavelength, the more harmful the uv radiation. however, lucky for us, uvc isn't able to penetrate earth's atmosphere. so while uvc is the most dangerous because it's the shortest wavelength, it's not a risk to the typical person because the sun's natural uvc emissions don. The shorter the wavelength, the more harmful the uv radiation. however, shorter wavelength uv radiation is less able to penetrate the skin. the uv region covers the wavelength range 100 400 nm and is divided into three bands: uva (315 400 nm) uvb (280 315 nm) uvc (100 280 nm). short wavelength uvc is the most damaging type of uv radiation.

Uva – the most common uv ray from the sun and most dangerous, uva can penetrate the skin down to the middle layer. uvb – a shorter wavelength than uva that can only penetrate the skin to the top layer. the earth’s ozone layer stops some uvb rays from reaching the surface. treated glass also can stop uvb rays. uvc – the ozone layer stops. There are three classes of uv light: uv a, uv b and uv c. uv a and uv b light cause sunburns and premature skin aging, and exposure to both is associated with the development of skin cancer. uv c.
