Population awareness of the radon issue in the Pilsen Region
JUDLOVÁ, Monika
Radon leaking out of the geological subsoil belongs to the most significant sources of population irradiation and as a proven human carcinogen it raises the probability of lung cancer occurrence. Nowadays many ways exist, how to protect yourself from the impacts of radon and from its higher concentration in buildings. However, the population isn't sufficiently informed about this issue. Raising the population awareness of the radon issue is therefore one of the aims of Czech radon programme. In the theoretical part of this bachelor thesis, the basic knowledge about radioactivity, ionizing radiation and its sources are summarized. The outline of quantities used in these matters was listed as well. This part by all means summarizes the radon issue, the occurrence of radon in buildings and its impacts on human health, as well as anti-radon measures. The practical part deals with the quantitative research, which task was to find out and evaluate the population awareness of the radon issue in the Pilsen Region. The research was carried out on the basis of questionnaire survey. To process the results, the methods of descriptive and mathematical statistics were used. With the help of two-choice t-test the stated hypothesis was confirmed: "The part of population of Pilsen Region which lives in family detached houses has statistically more relevant knowledge of radon issue that the part which lives in apartments." The residents of family houses gave most of the time better answers to questions than residents of apartments. The best answered questions were those dealing with the problematics which citizen face when building a house. On the other hand, the worst answered questions were the professional ones, dealing with comparing radiation burden of radon to nuclear power plants or the concentration of radon in the Czech Republic. The benefit of this thesis is a retrieved overview of the awareness of the radon issue among the residents of Pilsen Region. Moreover, the thesis could serve as a subject of future bachelor or master theses, with the option of extending the research part.
