Processing of dosimetric data of radiation workers and development of devices used by these workers.
ŽILINČÍK, Jakub
The bachelor thesis is focused on the analysis and evaluation of dosimetric data of radiation workers, whose personal doses are recorded in the Register of Professional Irradiation of the State Office for Nuclear Safety and ionizing radiation sources used in industry and healthcare. These data are drawn from the Register of Resources of the State Office for Nuclear Safety and data on resources used in healthcare from the Institute of Health Information and Statistics of the Czech Republic. Based on the analyzed data, I compiled an overview of individual occupational groups, their dosimetric data and development over time. I applied the same procedure with data on sources of ionizing radiation obtained from the Register of Sources of the State Office for Nuclear Safety and the Institute of Health Information and Statistics of the Czech Republic. To answer the research question, an analysis of the obtained outputs was performed, which were processed into graphs and then compared with each other over time. Based on the evaluation of the obtained data, it can be stated that the working group with the highest personal doses can include interventional radiologists and cardiologists, workers performing defectoscopy, logging and workers in the uranium industry. The development of doses of these radiation workers is described in detail in chapter 4.1. Furthermore, it can be stated that in the field of healthcare, an increasing number of all sources is observable, except for mammographic devices, the number of which has a slightly decreasing trend. Data on industry resources and other more detailed analyzes are provided in Chapter 4.2.

The role of a radiation monitoring and a dosimetric provision in the first phase of a local radiation emergency
VOJTA, Jiří
In the last decades, the sources of ionizing radiation have been used more and in various branches of medicine, industries, agriculture and research. Like each human activity, the usage of the sources of ionizing radiation is also connected with possible occurrences of accidents and emergencies. Such events can then cause damage to a person health or the environment . The usage of sources of ionizing radiation belongs to those few human activities in the world, where a big attetion is paid not only to the development of appli-cations but also to their safety. However, despite all of it, it is not possible to eliminate the risk of accidents and emergencies. Recently, there has been some talk of possible misuses of the sources of ionizing radiation. Such extraordinary events place high on the first response forces. One of the first re-sponse forces is Fire Rescue Service of the Czech Republic, the forces of which are lo-cated over the Cezch Republic. This thesis shall provide these forces with such infor-mation that they should be able, along with the authorities responsible for the radiation protection, to evaluate the situation and minimise effects on health, lives and environ-ment in the event of radiation extraordinary event. The purpose of this thesis is to solve local extraordinary radiation events (such as acci-dents during the transport of the sources of ionizing radiation, discovery of an unknown radiator). It does not deal with nuclear emergencies and accidents of other equipment, where the scope of the event and its consequences are of nation-wide importance. The first part of the thesis includes basic terms of the ionizing radiation and radiation pro-tection. The other part is focused on the radiation research, monitoring, response system and dosimetry devices. This part also includes materials for trainings and drills focusing on early identification of raiation hazards of an extraordinary event.

The atomic law and its application for utilization of significant X-ray sources (skiagraphy workplaces)
MAŠKOVÁ, Zuzana
In my thesis I dealt with the Atomic act and its application for important source of ionizing radiation at skiagraphy workplace. I worked out factual requirements of related legislation in order to obtain the licence of the State Office for Nuclear Safety for using an important source of ionizing radiation, to be specific, skiagraphic device in medical workplaces. Further, I worked out the real duties of permission holder and the requirements to ensure the radiation protection of patients and staff service. The aim of my thesis was to ease the orientation in contemporary legislation to the applicants for ``permission on treatment with important sources of ionizing radiation``, to give information how to proceed in elaboration of documents required for separate licensed activities and how to eliminate ossible insufficiencies and faults which are the most common in State Office for Nuclear Safety checking.
