A student researches the three bands of ultraviolet (UV) radiation and compiles the following data:
| UV Radiation Subtype | Wavelength Range | % Energy Absorbed by the Earth's Atmosphere |
|---|---|---|
| UV-A | 400 nm400\text{ nm}400 nm to 315 nm315\text{ nm}315 nm | 5% |
| UV-B | 315 nm315\text{ nm}315 nm to 280 nm280\text{ nm}280 nm | 95% |
| UV-C | 280 nm280\text{ nm}280 nm to 100 nm100\text{ nm}100 nm | 100% |
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.
