   Sammanfattning : The lepton and photon contamination of high energy photon beams for radiation therapy has been investigated computationally and experimentally. The contaminating particles will effect the quality of the beam by increasing the surface dose, degrading the uniformity of the beam, broadening the penumbra, and increasing the energy imparted outside the useful beam.
