This work aims to compare the technical parameters of individual measuring devices (radiometers and dosimeters) for the general public with similar professional equipment used by SÚJB České Budějovice and HZS České Budějovice and based on the comparison to answer the research question whether dosimeters and radiometers are available for the general public. able to compete with similar equipment used by SÚJB České Budějovice and HZS České Budějovice. The practical part of the work is focused on the quantitative processing of selected technical parameters of all selected investigated devices using multicriteria analysis and their comparison using CLA analysis. Based on the mentioned methods, the aim of the work is fulfilled and the research question is answered. For comparison, he was selected from professionals as a similar device URAD 115 (HZS České Budějovice) and FH 40 G (SÚJB České Budějovice). The following device was chosen from the devices intended for the general public: Gamma Scout, RD1008, SOEKS 112, BR 6, BR 9B and VOLTCRAFT Gamma-Check-A. The results of multicriteria and CLA analysis showed that the investigated devices intended for the general public are not able to compete with professional devices URAD 115 and FH 40 G. It was found that the investigated devices intended for the general public are characterized by lower weight and ability to detect beta radiation. Furthermore, the fact that the Gamma Scout device is able to detect alpha radiation in addition to the above radiation. The results of the work contribute to the evaluation of the usability of the investigated devices for the purposes of SÚJB České Budějovice and HZS České Budějovice in solving a radiation emergency. It also helps to assess the quality of the devices examined.

Knowledge of population about nuclear disaster at Fukushima in South Bohemian region
TŘEŠNIČKOVÁ, Tereza
This bachelor thesis deals with the knowledge of population about nuclear disaster at Fukushima in South Bohemian region. The goal is to determine the level of knowledge of population about the nuclear disaster and then compare the knowledge of people living in cities and people living in villages. In the thesis were set two hypotheses: H1: The knowledge of the population about nuclear disaster at Fukushima in South Bohemian region will reach at least 70 % and H2: The knowledge of the population living in cities about nuclear disaster at Fukushima will be statistically significantly higher than the knowledge of the population living in villages. To achieve the stated 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 10 questions. The survey consisted of 55 people living in cities and 54 people living in villages. The results of the survey show that the overall percentage of correctly answered questions was 50 %, which can be considered as an average result. 54 % of people living in cities answered the questions correctly and people living in villages 46 % correctly. The set goals were achieved and both hypotheses were refuted. The benefit of this bachelor thesis is to obtain a summary of knowledge of population about nuclear disaster at Fukushima in South Bohemian region. The results can be used like information material.

Nuclear accidents and subsequent measures to protect the population
SVITÁK, Daniel
This bachelor thesis deals with the protection of the population and subsequent measures in the event of a radiation emergency. When comparing the two largest nuclear accidents (Chernobyl and Fukushima), a great similarity was found not only in the implementation of safeguard measures, but also in the errors made by the responsible authorities. By comparing these events, we could answer the question of how the approach to protecting the population differed in the bipolar division of the world from the perspective of the "Eastern", which is represented by the former USSR and the view of the "Western" represented by Japan. With the resulting analysis, we confirmed that in both the USSR and Japan, this approach differed only in the source of the likely risk, which was given greater attention than the other risks. In case of comparison of the measures of protection of the population of the Czech Republic, which are mentioned in the emergency plans, with those introduced in the world in the case of The RMU, we concluded that the measures of the Czech Republic are on the same level and can be considered as a world standard. To support the resulting claims, the measures introduced at the Fukushima RMU are compared with those during the 2015 Zone Temelín emergency exercise. An integral part is the evaluation of the level of information of the Czech population in the field of protection of the population. An analysis of the results of the supplementary questionnaire survey confirmed the claim of low level of information of the inhabitants of the Czech Republic. Therefore, the work will also focus on the need to raise public awareness in the field of population protection and propose measures to raise the level of information to the required level.

Simulation of Robotic Search of Lost Radiation Sources
Cihlář, Miloš ; Lázna, Tomáš (referee) ; Žalud, Luděk (advisor)
Simulátory, společnostmi zabývající se robotikou hodně využívané, hrají důležitou roli při výzkumu robotů. Zrychlují, zjednodušují, zlevňují a usnadňují vývoj softwaru a algoritmů. Magisterská práce se proto zabývá návrhem systému, založeného na ROS2 a Gazebo simulátoru, umožňující simulaci pozemních robotů ve vnějším prostředí s možností hledat ztracené radiační zdroje. Práce navrhuje několik metod vytváření prostředí v Gazebo simulátoru včetně návrhu prostředí z mračna bodů a je vytvořen model čtyřkolového, smykově řízeného mobilního pozemního robota. Chování robota v simulátoru bylo ověřeno a upraveno pomocí teoretického dynamického popisu robota. Před simulací algoritmů pro hledání ztracených radiačních zdrojů je navržena metoda sledování referenční trajektorie pomocí proporcionálně integračního (PI) a lineárně kvadratického (LQ) regulátoru a navrhuje metodu k simulaci zdroje radiace a jeho měření. Hledání radiačního zdroje jsou použity dvě typově odlišné metody, kdy jedna je založena na prozkoumání celé oblasti a vytváří mapu radiace, a druhá metoda založená na částicovém filtru aktivně hledá ztracený zdroj záření.

Sorption of radionuclid 85Sr to soils from area nuclear power plant Temelín
Reidingerová, Markéta ; Nesměrák, Karel (advisor) ; Rychlovský, Petr (referee)
This thesis is focused on the study of sorption of radionuclide 85 Sr in soil collected in the area of a nuclear power plant Temelín. A single-batch method experiment was used when a solution of radionuclide 85 Sr of known activity was added to the soil. The experiments focussed on the influence of pH with the size of the sorption and the influence of the time of the contact of the solution with the sorption. During the experiment with the value of pH closest to the pH of underground water from the nuclear power plant Temelín, the sorption of soil was somewhere between 31 to 44 %. When the time influence on the sorption was examined, radionuclide 85 Sr was sorbed very quickly. For the comparison of the sorption size in connection with the time, for which it was chosen 120 minutes, the sorption was almost constant, reaching 40 to 48 %. Key words Radioactivity, radionuclide 85 Sr, sorption, nuclear power plant Temelín

Turnová, Štěpánka ; Goliáš, Viktor (advisor) ; Vylita, Tomáš (referee)
Radiohydrochemical exploration took place in east part of the "smrčinský" pluton between "Skalná-Plesná-Bad Brambach in years 2016-2018. The main aim of the exploration was location and thorough research of possible occurrence of waters with radioactive concretation higher than 1500 Bq/l. That is a value for radioactive mineral waters given by the "lázeňským" law number 164/2001 Sb. Most important area is Plesná-south where was discovered several springs with values exceeding 5000 Bq/l. Eminent spring is called "Břetislav-Radonka" and lies one kilometre southwest from the train station Plesná-Šneky with an activity of about 12.5 kBq / l 222 Rn and a flow rate of about 2.5 l / min. It is the most active surface discharge of radon mineral water in the Czech Republic Another significant source area is north of Skalna - north. These springs were discovered almost 60 years ago, Dr. Marie Zukriegelová. The main source of this area was named after its discoverer - the "Marie Z" spring with an activity of 5800 Bq / l 222 Rn.Further the research focused on historical radioactive conduit which were used to supply village Skalné with water. The conduit was separated on two "branches" and the younger one was built ten years after the first one. In both pipes were found radioactive waters and the most important...
