Like so many other things in life, moderation is key.
UV-C is instantly deadly to many micro-organisms, so lamps built to produce it
are often marketed as "Germicidal" lights.
To bigger, tougher, smarter organisms, like us, the degree of danger depends on
the duration and intensity of exposure to it. The effects range from none, through
suntan and sunburn, to skin cancer.

Why does UVC not affect the skin?
UVC radiation is almost completely absorbed by the ozone layer and does not affect the skin as it doesnt get to us.
What electromagnetic waves must sunscreen protect the skin?
UVa and UVb are considered beneficial to the skin as they are responsible for the production of Vitamin D and certain anti-cancer processes. UVc is considered carcinogenic and therefore anything above that is as well.

What is the definition of the word UVC?
There are two definitions for UVC. One being radiation in the ultraviolet spectrum and is more hazardous than UVB. The second is medical which has essentially the same meaning.
Why doesn't uvc reach us?
UVC is entirely absorbed by dead skin cells and is not dangerous. UVC may be a problem on broken skin and if shone direct into the eyes for long periods but as a general killer of virus and bacteria it is very useful. There are no known links between UVC and cancers and by killing virus's it may prevent you getting virus induced cancers.
Which part of the em spectrum can be used to kill bacteria?
Ultraviolet (UV) radiation, specifically UVC light, can be used to kill bacteria. UVC light has a short wavelength and high energy, which damages the DNA and RNA of bacteria, preventing their growth and reproduction. This property makes UVC light an effective tool for disinfection purposes.
What are 3 types of ultra violet radiation?
UVC UVB UVA
Can webcam work without CD?
If your webcam is UVC - USB Video Class compliant - and If you're running Windows Vista or Mac OSX 10.4 Tiger or 10.5 Leopard - the drivers for UVC webcams are built right into the operating system. No disc or drivers are needed.

What type of electromagnetic radiation can give you sunburn?
The main form of electromagnetic radiation that give you a sunburn is Ultra Violet (UV) radiation. (UV rays) Ultra-violet is furthered graded to UVa UVb and UVc. UVa - is necessary for the production of Vitamin D UVb - is required for certain anti-cancer process in the skin. UVc - has no beneficial function and is the most energetic and responsible for the majority of the sun burn.
Is uv radiation harmful?
UV radiation is very harmful in many ways, first off they are invisible rays that come from the sun, UV radiation is made of ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These rays burn skin and cause cancer. UVB and UVC penetrate the ozone layer. UVA and UVB cause skin cancer, for this reason, sunscreens are recommended that block UVA and UVB.
How is it possible for stratospheric ozone to offer any protection from UV radiation?
Ultraviolet radiation is a portion of the electromagnetic spectrum with wavelengths shorter than visible light. The sun produces UV, which is commonly split into three bands: UVA, UVB, and UVC. UVA is not absorbed by ozone. UVB is mostly absorbed by ozone, although some reaches the Earth. UVC is completely absorbed by ozone and normal oxygen. see related link
