description 97-023 This note describes a brief study into the effects of the radiation damage on the vertex detectorperformance. The noise increases as the detector is irradiated. Fixing the fraction of noise clusters to 0.1% by adjusting the thresholds brings about a loss in efficiency with increased irradiation. This loss in efficiency is parameterized, and some effects on the B->pi+pi- channel are shown.
