The thesis is based on the need of workplaces, where ionizing radiation sources are used, to implement a new legislation in the field of the Atomic Act effective since 1st January 2017. The thesis is focusing specifically on Radiation accidental exposures and radiation emergency on selected radiotherapeutic departments with linear particle accelerator. The theoretical part deals with definitions and categorization of radiation accidents and radiation emergency, relevant legal requirements and related work documentation related to this issue. The practical part deals with the evaluation of specific documents processed at two radiotherapeutic departments, the outcome of which is a proposal for their revision, which in agreement with the requirements of the new legislation and submitted for SÚJB´s approval. Primarily, for this purpose, it is a part of the practical part to create data file of actual radiation accidents and radiation emergencies in two specific workplaces and to analyze the causes of their occurrence. An interesting element is the choice of workplaces with a different producer of a linear accelerator, where are only two companies on the market. This choice was intend to determine whether the root causes of radiology accidents can have a causal link in relation to the technology in question of SW or accessories of the producer. The aim of the analysis is, in any case, awareness, prevention and iterative removal of the causes of accidents and the adoption of such measures in order to avoid any recurrence of events already occurred. All precautionary and follow-up measures, including responsibilities and competences, must be documented in the documentation of departments, with each holder of the resource authorization being required to keep this documentation in agreement with practice and current legislation. The thesis contributes to the detection of the causes of the accidents and the revision of the related documentation in order to be in agreement with the actual situation in the given depratments. |
