Does ozone absorb UV-C radiation?

UV-C: Smaller wavelengths between 250 and 290 are designated as UV-C radiation. UV-C is extremely hazardous, and is often used as a sterilizing agent. UV-C is completely absorbed by the ozone layer, which is fortunate since humans have no natural defense against this kind of radiation.

Which rays emitted from the sun are absorbed by ozone layer?
