Ionization chamber measurements were taken to determine the Relative Skin Dose from the Varian Clinac 4 (lead flattening filter). The effect of blocking tray material, field size, and scatterer-skin distance on the relative skin dose was investigated both on and off the central axis. It was found that the leaded glass tray enhanced the skin sparing effect of the beam by 25 to 30 percent.
