Sumario:An n-on-n design LHCb PR-01 prototype VELO detector was irradiated and equipped with LHC speed electronics. This detector was successfully operated in a test-beam and its performance assessed. After an irradiation dose corresponding to approximately two years of LHCb operation ($3-4 \times 10^{14}~ {\rm protons}/{\rm cm}^2$) full charge collection was obtained at 220~V and no degradation in resolution was observed. A signal-to-noise ratio, at full charge collection efficiency, of 21.5 was achieved. This impressive performance strongly supports the use of detectors of a similar design for LHCb.
