Type of UV
Radiation & Wavelength
UV-C (200-280 nm) is most traditionally referred to as germicidal UV with ability to kill bacteria, viruses, mold, and fungi.
UV-B
(280-315 nm) has also demonstrated effectiveness against Microbes
UV-A (315-400 nm) causes oxidation of proteins and lipids causing cell death in bacteria, & viruses
Effects of overexpose to UV Rays on Human Skin
UV-A Rays
Most controlled facilities such as tanning beds largely emit UV-A rays.
These rays accelerate the aging of skin cells and can cause extensive damage to
the DNA of the skin cells.
UV-A rays can also result in symptoms of skin damage such as wrinkles.
More importantly, UV-A rays can increase the risk of skin cancer due to the
damage to the skin cell DNA.
UV-B Rays
UVB rays are a little more intense than UV=A rays and have a direct
impact on the skin cells’ DNA. These rays can cause sunburns and prolonged
exposure can increase the risk of skin Although UV-B rays tend to cause the most
damage in terms of predisposing a person to different types of skin cancer,
UV-C Rays
UV-C rays are considered as germicidal; meaning it is able to kill
bacteria and viruses. It is the strongest of all the spectrum and is the
fastest new way of disinfection and sanitization, always avoid this light from
falling on your skin and you are not supposed to look at the light source
without eye protection.
UVA, UVB and UVC spectrums of UV light have ability to kill bacteria,
viruses, bedbugs, mold but all UV rays
are equally harmful to skin health and cautions have to be followed.
