Ionizing radiation and its influence on quality of human environment: Radon as a risk factor for health in the Czech Republic
Suchánek, Vladimír ; Šiftová, Jana (advisor) ; Kazmarová, Helena (referee)
Introduction: Environmental pollution is a major human problem since the mid-19th century. This situation is improving in the second half of the 20th century when human recognizes the consequences of industrialization. The issue of air pollution and for example, the negative effects of ionizing radiation, or the release of radon from the geological subsoil and its influence on the diseases as lung carcinoma, all these issues get more important. Purposes: The aim of the work is to find out whether there is an association between elevated radon concentration in buildings and some health indicators (incidence and standardized mortality rate). Using statistical analysis, it is examined if there is a statistically significant relationship among the variables and if these variables should be correlated together. The partial aims of the thesis are also to bring a qualitative view in the form of a professional interview and to visualize the acquired data into maps. Methods: The sources of data were the demographic yearbooks of the Czech Statistical Office, the database on the incidence of lung carcinoma from the National Health Information System and the measured values of the volume activity of radon (OAR) provided by the State Office for Radiation Protection. The data was processed by basic statistical...

Ionizing radiation and its influence on the quality of human environment: Radon as a risk factor for health in the Czech Republic
Suchánek, Vladimír ; Spilková, Jana (advisor) ; Kazmarová, Helena (referee)
The theoretical part of the thesis is divided into four chapters dealing with the problems of radon and its influence on the human organism. The first chapter summarizes the basic issues of human environment, interaction and division of the environment based on its function (use for life). The second chapter focuses on the radioactivity of environment, specifically on ionizing radiation, its formation and division, as well as its effect on human health. The next chapter is about radon, its formation, sources of radon, its distribution in the environment, measurements, protection against radon, the history of problems with radon and the Radon Programme of the Czech Republic. The last chapter of the theoretical part is dedicated to lung carcinoma, its origin, distribution, diagnosis, treatment and relationship with the incidence of radon based on surveys of selected epidemiological studies. The practical part of the thesis includes description of source data and methodology of processing data sets of radon equilibrium equivalent concentration (EEC), number of deaths by causes and population status. Chapter of results includes map outputs of radon EEC, mortality rates of carcinoma lung for men, women, and both sexes. Other parts of the outputs are the results of the correlation analysis of the...

Bioaerosols
Hladíková, Dita ; Hovorka, Jan (referee) ; Hůnová, Iva (advisor)
Bioaerosols and aerobiology are similar terms associated with the study of chemical, physical and biological fields. Bioaerosols in the air is a part of the aerosol containing particles of biological origin, such as viruses, bacteria, fungal spores, house dust mites and pollen. These particles can affect health of living organisms in terms of allergies, toxicity, carcinogenicity or infection and ultimately affect the planet's climate system because of acting as condensation nuclei for the formation of precipitation. The most studied biological effects of the above-mentioned on human health are reported respiratory symptoms and pulmonary diseases. This is due to almost continuous human exposure to these particles, both in the domestic environment, which includes mainly house dust mites, animal allergens, molds and bacteria, and outdoors, where a person is exposed to pollen and outdoor molds. In the case of interference with the climate system of the Earth there is a direct or indirect influence. Indirect effects include the creation of clouds and precipitation, which has the effect on the hydrological cycle of the planet. Scattering and absorption of solar radiation is considered a direct effect on climate change. Foreign literature was a crucial source of information on this topic.
