What dangerous effect does UVC radiation have on human skin?

UVC radiation is known to have harmful effects on human skin, with one of the most significant being its ability to cause skin burns. This type of radiation, which is part of the ultraviolet spectrum, is primarily absorbed by the Earth's ozone layer and does not usually reach the surface. However, when UVC rays are present, either through artificial sources (such as certain types of tanning beds) or when the ozone layer is depleted, they can penetrate the skin and lead to immediate skin damage, which manifests as burns.

Skin burns can result in redness, swelling, pain, and peeling, similar to the more common effects associated with UVA and UVB radiation, but potentially even more harmful. Understanding the dangers associated with UVC radiation emphasizes the need for protective measures, such as wearing appropriate sunscreen and avoiding excessive exposure to artificial UV sources.

The other options do not accurately describe the effects of UVC radiation on human skin. Permanent tanning is typically associated with UVA and UVB exposure, while the idea that UVC radiation can be safely ignored is misleading given its potential for harm. Likewise, the notion that UVC can produce a glowing effect does not correspond with its biological effects on the skin and is not a recognized consequence of UVC exposure.
