Surface Dose in Electron Beams and Association with High Energy X-Ray Beams

  • J. C. Rosenwald

Abstract

Electron treatments give skin reactions far more severe than high energy X-ray treatments at equal doses. Sometimes these reactions may become even too severe for the treatment to be continued at the dose initially planned. This paper describes how the surface dose is modified according to the different treatment parameters and what can be done to keep it as low as possible.
