When DNA molecules are exposed to too much ultraviolet radiation, their atoms can become over-excited, and accidentally bond in ways that result in molecular injuries known as dimers.

Haigh's measurements showed that visible radiation increased between 2004 and 2007, when it was expected to decrease, and ultraviolet radiation dropped four times as much as predicted.

They can also be used for biological labeling because of their low toxicity, chemical stability, and intense luminescence when excited by near - IR radiation, which can penetrate tissue much better than higher energy radiation such as ultraviolet, as is often required with quantum dot labels.

On Earth, temperature inversion occurs because ozone in the stratosphere absorbs much of the sun's ultraviolet radiation, preventing it from reaching the surface, protecting the biosphere, and therefore warming the stratosphere instead.

While Earth's lower atmosphere is about one percent water vapor (although it seems much higher in the humid Louisiana summers), the upper atmosphere, where ultraviolet radiation can penetrate, is very dry: a cold trap, a combination of pressure and temperature, prevents water vapor from rising high in the earth's atmosphere.
