Risk assessment associated with the release of radioactive iodine from nuclear medicine department during a fire
RAMBOUSKOVÁ, Lucie
Nuclear medicine is the branch of medicine that is used to diagnosis and treatment with radioactive isotopes. Nuclear medicine is one of the least burdensome non-invasive methods of investigation. In contrast to diagnostic radiology, which shows the structure of organs , nuclear medicine provides information not only anatomical , but also on organ functions and metabolism. In many cases it is a unique diagnostic test that can detect the disease or its extent before, and thus increase the chance of successful treatment. When working with open emitters for nuclear medicine department can be assumed that may occur in the expected manner of use of radioactive sources only incident of First Instance ( spilling or splashing radiopharmaceuticals, patient pollution ) and very rarely an emergency occurs the second stage (the loss or theft of resources radiation). An extraordinary event is the third-degree radiation accident with very minimal probability of occurrence. The aim of the Bachelor thesis is to map the distribution and the storage of radioactive iodine in the Department of nuclear medicine of the hospitals in the Czech Republic, to determine the level of knowledge of the medical staff and members of the fire rescue Corps and their application in practice, in the release of radioactive iodine, and assess the degree of risk associated with the release of radioactive iodine in the fire. The hypothesis assumes that the medical staff and members of the fire rescue Corps know how to proceed in cases of leakage of radioactive iodine from the Department of nuclear medicine, and that the level of risks associated with the release of radioactive iodine in the fire is negligible. It is a form of qualitative research, research-questionnaire and interview-driven method. In an interview, polootevřený will be used and the type of closed questions. The research staff of the Department consists of a set of nuclear medicine and the members of the fire rescue Corps. Thesis will be used for more detailed study of the issue. It may also be used in lectures and seminars, health workers, and a fire department Rescue Corps.

The most considerable of radionuclides at the accident of the nuclear power station, the experience of Chernobyl
HORÁKOVÁ, Magdaléna
At the nuclear power plant accident, the radionuclides with very short half-life come to enviroment, they decay the period from several second to several months. On the other sides come to enviroment radionuclides with long half-life. Their radionuclides occur in surrounding of the power plant for hundreds of years before they decay totally. Immediately after a nuclear power plant accident, radioiodine represents the most severe health hazard for population. Because it is a radionuclide with short half-life, it causes the danger during first months after the accident. Its health hazard lies in the fact, that it gets to food chains and irradiates a man, who consumed contaminated water and food. Radiocaesium and radiostrontiom are the next important radionuclides. They have long half-lifes, it means that will decay after hundred years after the accident and they endanger population a long time after the accident yet.
