Irradiation of the population from natural sources
UHLÍŘOVÁ, Daniela
Natural sources of radiation cause much higher exposure than artificial sources and can come in many forms. Natural sources of ionizing radiation are cosmic rays and natural radionuclides. Radon accounts for the largest percentage of the population's exposure. In the Czech Republic, radon occurs to a large extent, and because of this, we are among the countries with the largest volumetric activity of radon. The aim of the submitted bachelor's thesis was to find out and compare the awareness of the population in the area of natural sources of ionizing radiation in selected localities with high and low incidence of radon, namely Příbramsko and Mostecko. The theoretical part contains knowledge about radioactivity, biological effects of ionizing radiation, natural sources of ionizing radiation and quantities associated with ionizing radiation. A section is also devoted to the radon issue, health complications associated with radon and the radon program, which summarizes anti-radon measures. In the research part, the results of the questionnaire survey are summarized using graphs. These results are further processed using statistical methods, thanks to which both given hypotheses were confirmed. The first hypothesis examined whether the total awareness of the population would reach at least 70%, which was confirmed using a one-sample t-test. The second hypothesis related to the comparison of the knowledge of the population in the area of natural sources of ionizing radiation in people living in a locality with a higher incidence of radon and in people living in a locality with a lower incidence of radon, where the awareness of people in localities with a higher incidence of radon should be considerably higher. The hypothesis was confirmed using a two-sample t-test.

Public awareness about ionizing radiation from natural sources
HRBKOVÁ, Jana
Ionizing radiation comes from artificial or natural sources. Greater collective exposure of the population is caused by natural resources. Natural sources of ionizing radiation are cosmic radiation and natural radionuclides (cosmogenic and terrestrial). Radon and its products are the main contributors of natural irradiation. In the Czech Republic, the average indoor radon concentration is 118 Bq/m3, which ranks us among the countries with the highest average concentration of radon in dwellings. Radon is considered to be the second leading cause of lung cancer. Due to the possible health risks from radon, there is an effort in our country and in many other countries to regulate radon concentration in some way. The purpose of this diploma thesis was to find out how much is the public aware of the issue of ionizing radiation from natural sources and to create information material on this topic. Also compare how some countries approach the issue of radon regulation. In order to collect necessary data for my thesis a questionnaire survey was conducted. I also used professional resources. The electronic survey, which I created on website www.vyplnto.cz, was filled in by 362 respondents. All the results of the survey were displayed in pie charts. Questions no. 3-16, which were focused on awareness, were also displayed in bar charts, which show the percentage of correct answers by level of education. Thanks to the data from the survey I was able to answer research questions. In the first research question, I asked whether the public is sufficiently informed about ionizing radiation from natural sources; in the second research question, I wanted to know who has the least awareness on this topic based on education. I evaluated that the public is not sufficiently informed and people with just primary education have the least awareness about this topic. In the Canva program, I also created information material about ionizing radiation, in the form of a double-sided A5 leaflet. It can serve to increase public awareness of the issue. With help of professional sources, I also found out how some countries regulate radon concentration. I paid particular attention to the Czech Republic, where the history of radon regulation dates back to the 1990.

Municipalities and region websites - analysis of information provided to citizens on the field of protection of population
VEBEROVÁ, Tereza
This thesis deals with the issue of protection of population in the Czech Republic territory. The aim of this paper is to evaluate the information provided to the population on the websites of municipalities and regions in the field of population protection. A partial goal is to determine the level of the education of the population in this area. To achieve these goals an analysis of websites of selected municipalities and municipalities with extended powers is performed and also a questionnaire investigation of level of knowledge of population on this topic is held. First, the terms of civil protection, civil defense and protection of population are defined. Then the concepts which outline the historical development to the present situation of protection of population in our territory are presented. In the next part, status and tasks of self-governing authorities and individuals in this system are mentioned. The essential part of this paper is the tasks of protection of population and their characteristics which are indespensable component of knowledge in this issue. Particulary it concerns: warnings, notifications and providing of emergency information; unified system of warnings and notification; hiding; individual protection; evacuation; emergency survival. Following the theoretical part which is based on literary research of documents dealing with given issue, the paper further continues with the empirical part which on the opposite is based on analysis and comparison of content of information in the section of the protection of population on websites of selected municipalities. It is concluded from this analysis that the amount and quality of the information provided on the websites of municipalities is insufficient. Further the questionnaire investigation is held from which it is concluded that the level of knowledge of population in the field of protection of population is low - the most frequent answer to concrete topics from the field of population protection was "I do not know" (88 %).

The awareness of the Vysočina region population about the nuclear disaster Černobyl
ROYIK, Tetyana
The diploma thesis deals with the awareness of population of the Vysočina Region of the Chernobyl nuclear accident. The aim of this thesis is to find out the level of knowledge of the population about this accident and then to compare the knowledge of the population aged 18-44 and over 45 years. Two hypotheses were set in the thesis, H1: More than 2/3 of all respondents in the Vysočina Region will have more than 60 % of correct answers in a questionnaire concerning the knowledge of the Chernobyl nuclear accident, and H2: Respondents over 45 will have significantly higher knowledge of the Chernobyl nuclear accident than inhabitants under 45 years of age. In order to achieve the defined objectives and to verify the hypotheses, a questionnaire was prepared, a questionnaire survey was carried out and then the results were evaluated using the methods of descriptive and mathematical statistics. The questionnaire consisted of 15 questions. The research group consisted of 100 inhabitants aged 18-44 and 100 inhabitants aged over 45. The results of the questionnaire survey show that the overall success-rate of the answered questions was 66 %. Residents aged 18-44 responded correctly in a total of 61 % and residents over 45 in 71 %. The stated aims of the thesis were achieved and both hypotheses were confirmed. The benefit of the thesis is mainly the acquired picture of the state of awareness of the population of the Chernobyl nuclear accident in the Vysočina Region. The obtained results of the diploma thesis can be used, for example, by crisis management authorities related to the issue of nuclear energy or protection against ionizing radiation, both in connection with preparation for these situations and with a focus on preventive educational activities.

Awareness of population issues in the context of weapons of mass destruction
ŠTURMOVÁ, Lenka
The aim of this diploma thesis was "To Analyse the awareness of the population in the area of South Bohemia region in context of emergencies in case of using weapons of mass destruction". In the theoretical part of the thesis the issue of the weapons of mass destruction is described from the description of particular groups to some historical consequences, to their arrangement or detailed description of the main types of weapons, and their harmful effects on a human body. As the issue is really wide, the main text is focused on the basic specification for easier understanding. Not many details are presented, but the most important information and some sidelights were given the priority. The target of the thesis was not to prepare a detailed and broad description, but on the other hand the comprehensive view of the studied issue, so a reader can obtain clear and brief analysis of the topic. For the practical part of the thesis the quantitative research and the method of a survey for obtaining data were chosen and done from January to March 2019. The questionnaire consists of four parts. Each part is specifically orientated. In the introductory part of the questionnaire there are three initial questions given to divide the responders according to their gender, age and education. After that there is the part A, which consists of ten questions, and it is aimed at the public awareness about the issue of public safety. The other parts B, C and D have five questions each, and they are aimed at the particular weapons of mass destruction - chemical, biological and nuclear weapons. The main goal of the survey was to find the level of the public awareness in South Bohemia region. The obtained data show that the correct answers reached approx. 55 %, but the range of all particular correct answers was from 30 % up to 83 %. These results show that there is potential room for improvement of the public awareness by simple and well-arranged brochures, by creating professional web-sides or groups for modern society that can use social network such as Facebook or Instagram. The diploma thesis can be also used as an educational material.

The use and misuse of ionizing and non- ionizing radiation
MAJEROVÁ, Natálie
This dissertation is divided in two parts: a theoretical, and a practical one. The purpose of the theoretical part is to introduce the reader to the elementary terms of ionizing and non-ionizing radiation, their types, sources, influence on humans, as well as possible manners of their use and abuse. The goal of the thesis is to evaluate possible use and abuse of ionizing and non-ionizing radiation. In the interest of clarity, the gathered information was included in the results chapter as a chart. The practical part deals primarily with the first research question whose aim was to establish the level of public awareness about ionizing and non-ionizing radiation. To get answers, the method of data collection by means of a questionnaire survey was employed. The questionnaire consisted of 19 questions in total. The first 3 questions split the respondents into categories based on their gender, age, and educational attainment. The main part of the questionnaire involved 12 closed-ended questions, evaluated by a test. The survey was concluded by 4 opened-ended questions. The questionnaire survey provided a multitude of findings, most importantly that the average public awareness of ionizing and non-ionizing radiation is 57.7%. Finally, the discussion part answers the second research question which sought to determine whether there's a greater danger of ionizing radiation sources being abused.

The level of awareness of inhabitants about the problems of large-scale electrical power failures
HAJDAJOVÁ, Natálie
The diploma thesis deals with large-scale electrical power failures, in other words about blackouts. The work is then divided into two sections. The theoretical part describes the (critical) infrastructure, which is undoubtedly part of the electrical energy, further introduces the reader to the electricity system of the Czech Republic and also with blackout as such. The last chapter analyzes some important outages in the world and in total of eight blackouts and trying to point out how technical defects, control errors or extreme weather manifestation can negatively affect the lives of each of us. In the practical part are mentioned two objectives. The first, main aim of the diploma thesis is to find out and assess the level of knowledge of inhabitants about the problems of large-scale electrical power failures, with a hypothesis claims that awareness of the population in selected municipalities with extended competence does not reach 80 %. The exploration is carried out on two municipalities with extended competence Uherské Hradiště and České Budějovice. Obtained data are then evaluated by a comparative approach. Based on the results of the research, remedies are being suggested, purpose of the remedies is to improve the system of informing the population about the subject matter. This is the second objective. According to the objectives and for the needs of my thesis, I used the method of collecting data in the form of a questionnaire survey which carries elements of quantitative research. The thesis and its results can serve as a study material which could be further used for other research. Also it may be inspired by considering how to improve the awareness of the inhabitants.

VACEK, Jan
The diploma thesis is focused on the assessment of the level of public awareness on the issue of oil shortage in the territory of the South Bohemian Region and the comparsion of the obtained data with the results obtained in the region of Pilsen. The results of this research are linked to the second objective of proposing measures to improve the information system on the given issue. For the needs of the thesis, quantitative research was chosen as a questionnaire survey. The questionnaire itself consists of 17 semi closed questions, with 3 filtering questions in the introduction, ranking respondents by sex, age and municipality, followed by 14 specific questions. The purpose of the research is to determine the level of public awareness of possible regulatory measures related to the declaration of the state of oil shortage, focusing on fuel shortages, powers of state administration and self-government authorities and a general overview of the oil security of the Czech Republic. The data obtained suggest that the average knowledge of the correct answers averages around 65 % on average, but succes rates vary from 30 to 94 %. Questions with a low average success of the right answers are potential topics for improving awareness, for example through short TV spots, training courses, or information brochures. The diploma thesis can be used for educational purposes as a starting material for follow-up research, or it can serve as an inspiration for finding a suitable way of communicating with the public in the field of crisis management.

ČERNÁ, Tereza
The thesis deals with the knowledge of the population about the nuclear disaster at Fukushima in the Vysočina Region. The goal is to determine the level of knowledge of population about the accident and then compare the knowledge of people aged 18-44 years and older than 45 years. In the thesis were set two hypotheses, H1: the knowledge of the population in the nuclear accident will be close to normal distribution and H2: people under 45 years will have statisticly higher knowledge than older people. To achieve the setted goals and to test the hypotheses, a questionnaire was compiled and a survey was made. The results of the survey were evaluated by methods of descriptive and mathematical statistics. The questionnaire consisted of 11 questions. The survey consisted of 100 people aged 18-44 years and 100 people aged over 45 years. The results of the survey show that the overall percentage of correctly answered questions was 63,3 %, which can be considered slightly above average. 66,1 % of people aged 18-44 years answered the questions correctly and residents over the age of 45 years 60,6 % correctly. The set goals were achieved and both hypotheses were confirmed. The benefit of this thesis is to obtain a picture of knowledge of public in the nuclear disaster at Fukushima in the Vysočina Region. The results can also be used for crisis management authorities within the preparation and preventive educational activities focused on the issue of nuclear energy and radiation protection.
