Abstract

Surface dose was measured in an extrapolation chamber and was found to be less than previously reported. The slope of the build up curve was less steep with the Clinac 4 than with 60Co and much steeper with the Clinac 35 at 25 MV than with the betatron at the same energy. The gradient of the depth dose curve in the build up region is probably the best indicator of skin damage.
