Relative surface doses (RSD) for 10 MV x rays were measured and analyzed with an acrylic resin block tray present in the beam. It was found that the secondary electron contamination becomes significant for large fields in isocentric set-ups. Medium and high Z filters are investigated and suggested to be used to reduce RSD.
