They are also strongly linked to skin cancer.
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.
Which is more harmful UVA or UVB?
UVA light, also known as long-wave light, accounts for about 95% of the UV light that reaches our skin. Although both UVA and UVB are bad for skin, UVA rays are more of a threat because a much larger percentage of them reach earth’s surface. UVA light has a wavelength of 320 nm to 400 nm.
What is the difference between UVA and UVB radiation?
There are two basic types of ultraviolet rays that reach the earth’s surface—UVB and UVA. UVB rays are responsible for producing sunburn. In addition, the UVA rays penetrate more deeply into the skin and play a greater role in premature skin aging changes including wrinkle formation (photoaging).
What are the types of UV radiation?
The most common form of UV radiation is sunlight, which produces three main types of UV rays:
Why is UVC 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.
