title: Xeroradiography in radiation therapy.
abstract: The xerographic technique has been introduced at Radiumhemmet for direct field control in therapy with high energy photon radiation (60Co-unit, 6 MV linear accelerator and 42 MeV betatron). The xerograms are of a sufficiently good quality for this purpose. The advantages and disadvantages connected with the xerographic facilities at present available are discussed.
