Summary

It is responsibility of every workplace that utilize ionizing radiation sources under medical exposure to abide the principles of radiation protection, including compliance with the ALARA rule (As Low As Reasonably Achievable). The aim of this thesis was to assess the level of optimization of radiation protection of medical professionals on PET/CT departments with respect to the received personal dose, personal protective aids utilization, construction of the premises and also the experience and skills of the workers. All PET/CT and PET/MR departments in the Czech Republic, including two non-PET sites, were asked to participate in the study by completing two electronic questionnaires and providing other important information. Out of the total number of 22 surveyed departments in the Czech Republic and Slovakia 18 workplaces responded the first questionnaire. The return rate of the questionnaire 2 was 55,6 %. Subsequently, 10 sites were included in the study. Subsequently, the obtained personal dosimetry data (respecting GDPR), information about administered activities, responses to the subjective evaluation of the situation of executives and also received plans of the construction of the premises were processed and compared. A regression analysis was used for statistical assessment. The sets of values were compared by Mann-Whitney and Kruskal-Wallis non-parametric tests. For each worker the average effective and equivalent doses in relation to the applied activity was calculated as well as the collective dose for each workplace. In the next step, the received value of Hp(10) and HT was calculated from 1 GBq per worker (in µSv). The results revealed differences in the level of radiation protection between individual workplaces. Equipment and sufficient staff play a major role. Differences were also found in the dose received on the skin of the hands. The assumption that utilization of positron radiopharmaceuticals is connected to a greater radiation burden has not been confirmed, as well as that the acquisition of automatic delivery systems does not decrease the collective dose automatically. Practical skills and experience of employees are important. Specific recommendations to improve the level of optimization were proposed for individual departments.
