[The Mevatrom KD 80/67 linear accelerator]

Technical equipment of radiotherapeutic wards is presently supplemented with irradiators on the principle of a linear accelerator. The paper briefly describes the principle of linear accelerator with standing wave and its basic technical parameters. Data on electric, mechanic and densitometric properties of this apparatus and accessories are presented. Therapeutic beams of bremsstrahlung and electron radiation were characterized in the whole range of energy, i.e. 0.961 and 3.204 pJ (6 and 20 MV) for bremsstrahlung and 0.961 to 3.364 pJ (6 to 21 MeV) for electron radiation. In the last part the performed hygienic measurements are also described.
