From the first contact of patient with simulator to therapeutic application of radiation is the radiotherapy in direct contact with devices. The radiotherapeutical units are irreplaceable because the radiation therapy is impossible without these. The process of radiotherapy became more difficult with production of modern devices, using new techniques of irradiation, using new accesories, aids and especially with development of computer technology. This fact enabled approximation to the exacting requirements of modern radiotherapy. Today is the spectrum of radiotherapeutical units stabilize on several types which include most of clinical demands. These are linear accelerators, cobalt and cesium isotopic units, therapeutic X-ray devices and the automatic afterloading systems for brachytherapy. Today is the attention paid to expansion of technical abilities of existing units rather than to searching of new types of radiation sources. Using of unconventional sources of radiation, especially the neutron sources and accelerators of heavy parcticles, is exception. The subject of this bachelor essay is adumbrate meaning of devices in radiation therapy. Essay provide list of the most frequently devices which used for therapeutic application of ionizing radiation. These therapeutic units are generally specified in essay and there are provided important informations about incident of radiothe-rapeutical units at departments of radiotherapy in the Czech Republic
