A student researches the three bands of ultraviolet (UV) radiation and compiles the following data:

UV Radiation SubtypeWavelength Range% Energy Absorbed by the Earth's Atmosphere
UV-A400 nm400\text{ nm}400 nm to 315 nm315\text{ nm}315 nm5%
UV-B315 nm315\text{ nm}315 nm to 280 nm280\text{ nm}280 nm95%
UV-C280 nm280\text{ nm}280 nm to 100 nm100\text{ nm}100 nm100%

Using the data in the table, explain why UV-C is potentially the most damaging subtype of ultraviolet radiation to human tissue, but does not present a danger to the population on the Earth's surface.
