UVérzékeny

UVérzékeny is a term used to describe materials or substances that are sensitive to ultraviolet (UV) radiation. This sensitivity can manifest in several ways. For instance, some materials might degrade, change color, or lose their structural integrity when exposed to UV light over time. This is a common phenomenon with plastics, dyes, and certain organic compounds. The UV radiation can break chemical bonds within these materials, leading to the observed changes.

In other contexts, UV sensitivity refers to the ability of a substance to undergo a chemical reaction or change when exposed to UV light. Photochromic materials, for example, are UV-sensitive in this way. They darken when exposed to UV radiation and return to their original state when the UV source is removed. This property is utilized in applications like transition lenses for eyeglasses.

The term can also be applied to biological organisms or components. Some microorganisms are UV-sensitive and can be killed or damaged by UV radiation, which is the principle behind UV sterilization. Similarly, certain biological molecules within living cells, like DNA, can be damaged by UV exposure, leading to mutations. Understanding UV sensitivity is crucial in various fields, including material science, conservation, and public health, to protect sensitive items and living beings from the detrimental effects of UV radiation.
