What are UVC rays?
Correspondingly, what does UVC rays stand for?
UV radiation is made up of three types of rays -- ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). UVC is the most dangerous type of ultraviolet light but cannot penetrate earth's protective ozone layer. Therefore, it poses no threat to human, animal or plant life on earth.
Furthermore, what does UVC do to humans? UVC Effect on Skin Acute (short-term) effects include redness or ulceration of the skin. At high levels of exposure, these burns can be serious. For chronic (long-term) exposures, there is also a cumulative risk, which depends on the amount of exposure during your lifetime.
Secondly, are UVC rays dangerous?
UVB rays, which affect skin's top layer, cause skin cancer and most sunburns. Although UVA and UVB rays pose the greatest risk for sun damage, people who work with welding torches or mercury lamps may be exposed to UVC rays, the most dangerous type of UV radiation.
Why are UVC rays the most dangerous?
But, on the other hand, there are a few sources that mention that UVC is the most dangerous wavelength that can cause skin cancer. The shorter-wavelength, higher-energy UV radiation associated with the UVC category is very strongly absorbed by most organic materials.
