Analysis of population knowledge about radon in selected localities in the Czech Republic
STARÁ, Adéla
This work summarizes information about radioactivity, natural sources, and radon. It also addresses health complications associated with radon, sources and ways it penetrates buildings. Furthermore, it discusses the radon program, which outlines anti-radon measures aimed at protecting the population from radon exposure through effective building modifications. The aim of the presented bachelor thesis is to determine the level of awareness among the population of the South Bohemian Region about radon. It compares the awareness of the population in the South Bohemian Region about radon in the age category up to 40 years and in the age category over 40 years. A questionnaire survey was used to achieve this goal. This survey determined the extent to which residents of the South Bohemian Region are familiar with the topic of radon. On average, people answered correctly 68 % of the time. The research section summarizes the results of the questionnaire survey using graphs. These results are further processed using statistical methods. Thanks to these methods, both hypotheses were confirmed. The first hypothesis examined whether the awareness of the population of the South Bohemian Region about radon would reach at least 70 %, which was confirmed using a one-sample t-test. The second hypothesis concerned comparing the knowledge of the population of the South Bohemian Region about radon. It was investigated whether the awareness of the population in the age category over 40 years would be statistically significantly higher than the awareness of the population in the age category up to 40 years. The hypothesis was confirmed using a two-sample t-test.

Realization of a polyfunctional building Pardubice
Výborný, Václav ; Doubek, Rostislav (referee) ; Kantová, Radka (advisor)
The main contens of the thesis is solving a construction-technological project substructure and the upper shell construction of a polyfunctional building in Pardubice. Excavation and foundation work are done in section A and B1 and B2. Drilled piles are foundation of a polyfunctional building. Drilled piles are support of reinforced concrete grillage, which are from strips foundation and foundation pads. Cast-in-place concrete frame is a form of load-bearing structure, which contens plate ceilings, pillars and walls. Peripheral masonry is from hellow clay blocks, which are between cast-in-place concrete frame. Diploma thesis includes technical report, plan of building side, schedule and the budget of the building, technological instructions, radon prevent, control and testing plan, safety, balance resources, selected constructional details, machinery composition, bill of quantities.

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.

Relation between the level of Radon in the underlay and in structures in Central Bohemia
KADLECOVÁ, Zdeňka
Radon is a natural radioactive gas originating from a radioactive transformation of uranium. It penetrates the Earths surface from the geologic subsoil and cumulates in buildings where it can reach hich concentrations. Building material is also a radon source in resident premises. Water is another radon source. It isimportant to realize that the building materials of a natural origin as well as water supplied to the houses also gain a higher volume radon activity from the geologic subsoil. Hence my thesis particularly focuses on the building subsoil. My thesis that the beologic subsoil isa significant radon source affecting the radon volume activity in the objects, however, a high radon index of the eoloic subsoil does not necessarily mean that a high radon volume activity values will be measured in the building situated on the subsoil. It very much depends on the technical condition of the object and the way of its ue.
