Ozone is known to absorb ultraviolet (UV) radiation on Earth, but other materials can also absorb UV light, including many solids, liquids, and some gases. Common materials that effectively absorb UV radiation include simple window glass, titanium dioxide (TiO2), and beryllium, which are also resistant to environmental factors. For applications like building a base on Mars, selecting materials that can shield against UV radiation is crucial due to the planet's lack of ozone. Human skin is another example of a biological material that absorbs UV light. Understanding these materials is essential for protecting against UV exposure in various environments.
