Risk analysis in relation to the civil protection of the City of Tábor
ŽILINČÍK, Jakub
The thesis deals with risk analysis in the city of Tábor. The first goal of this work was to identify the most serious anthropogenic and naturogenic risks in the city of Tábor and their subsequent analysis. The second goal was to create a risk analysis from the perspective of the population and subsequent comparison with the city's own risk analysis. To achieve these goals, multiple risk analysis methods have been used to examine the issue from multiple angles. One of the ways to identify the most serious anthropogenic and naturogenic risks in the city of Tábor was a questionnaire survey, which included a semi-quantitative "PNH" method, which the respondents had to fill out. The research group consisted of 1024 respondents from the city of Tábor. Within the questionnaire survey, it was found that 34.1% of the inhabitants of the cadastral area of the city of Tábor have experience with fire or explosion in buildings and industry. Another note that is worth noting is the fact that 10.5% of the research group has encountered a life-threatening event in their lifetime, yet in a semi-quantitative analysis from the point of view of the population, the level of risk for this event was moderate. On the contrary, in the author's semi-quantitative risk analysis, the risk of leakage of a dangerous substance was classified as an undesirable risk. In response to the output of the multicriteria analysis and semi-quantitative analysis, the ammonia and chlorine leakage was modeled using TerEx software. The findings presented in this thesis are intended for the general public, mainly for the inhabitants of Tábor, who want to learn something about the risks occurring in their area of residence.

Processing of dosimetric data of radiation workers and development of devices used by these workers.
ŽILINČÍK, Jakub
The bachelor thesis is focused on the analysis and evaluation of dosimetric data of radiation workers, whose personal doses are recorded in the Register of Professional Irradiation of the State Office for Nuclear Safety and ionizing radiation sources used in industry and healthcare. These data are drawn from the Register of Resources of the State Office for Nuclear Safety and data on resources used in healthcare from the Institute of Health Information and Statistics of the Czech Republic. Based on the analyzed data, I compiled an overview of individual occupational groups, their dosimetric data and development over time. I applied the same procedure with data on sources of ionizing radiation obtained from the Register of Sources of the State Office for Nuclear Safety and the Institute of Health Information and Statistics of the Czech Republic. To answer the research question, an analysis of the obtained outputs was performed, which were processed into graphs and then compared with each other over time. Based on the evaluation of the obtained data, it can be stated that the working group with the highest personal doses can include interventional radiologists and cardiologists, workers performing defectoscopy, logging and workers in the uranium industry. The development of doses of these radiation workers is described in detail in chapter 4.1. Furthermore, it can be stated that in the field of healthcare, an increasing number of all sources is observable, except for mammographic devices, the number of which has a slightly decreasing trend. Data on industry resources and other more detailed analyzes are provided in Chapter 4.2.
