description: The topic of the final qualifying work: "Physical aspects of quality assurance of intracavitary therapy". This graduate qualification work is devoted to the description of the main physical aspects of quality assurance, that is, a list of measures to ensure the proper effectiveness of intracavitary irradiation. The paper describes the procedure for intracavitary irradiation, notes the design features of devices for this type of irradiation. In addition, the specifics of the operation of three sources of gamma radiation for intracavitary devices are considered: iridium-192, cobalt-60, cesium-137. The work was carried out with the involvement of the resources of the Leningrad Regional Clinical Hospital, where the practical experimental part was carried out. The peculiarities of using the modern device for intracavitary irradiation microSelectron-HDR were noted. Measurements were made with a Nucletron Well Type Ionization Chamber to estimate the percentage of difference between operational activity and activity recalculated according to the ionizing radiation source nameplate. An experiment was also carried out to determine the accuracy of the delivered dose on a microSelectron-HDR intracavitary irradiation apparatus using a PTW Farmer ionization chamber, a PTW Unidos dosimeter and a Oncentra gliding system. In addition, the work noted a list of necessary daily checks and manipulations on the intracavitary irradiation apparatus, which must be carried out by the engineering and physical department responsible for monitoring ionizing radiation in the radiotherapy department.
