The evaluation of radiation burden of patients and the possibility of radiation emergence and management of emergencies at the nuclear medicine department of the Hospital České Budějovice, PLC
DAŇOVÁ, Kristína
The aim of my thesis was to evaluate radiation consequences in patients, and to evaluate unusual occurrences stemming from radiation at the department of nuclear medicine in hospital Ceske Budejovice. In the theory part, I worked with professional literature, applicable laws and internal documentation provided by the department of nuclear medicine in hospital Ceske Budejovice Plc The thesis reacted to the need of the department of nuclear medicine (dept. NM) in hospital Ceske Budejovice to evaluate the optimisation of doses for the patients and set local diagnostic levels. Different organisations worldwide deal with the question of optimising radiation protection, and their recommendations and standards are used in the Czech Republic. For this purpose, it is necessary to know the real activity of radiopharmaceuticals applied in each examination and to conduct a forecast resulting in effective doses also based on CT scans. The thesis also evaluates the occurrence of special radiation events really experienced at the department of NM (nuclear medicine) in the hospital mentioned above, the reasons for these events happening and precautions preventing them from happening in future. The owner of the permission for this activity, meaning the use of the source of ionizing radiation, has the duty to keep all documentation and paperwork in accordance with the law regulating nuclear power, abide by the rules of good practices and the real state of allowed practice. The occurrence of unusual events is closely connected with the documentation - internal emergency plan and monitoring program. (Law 263/2016) Therefore, it was recommended to compare these to the actual state and to review them based on the facts found. The values of applied activities and effective doses found were compared to the values published in the last report from UNSCEAR in 2016 and national referential values published in the bill about radiation protection no 422/ 2016. All results were inputted into tables and graphs. It was found that the applied activities at the department of NM in hospital Ceske Budejovice are in agreement with the values presented in UNSCEAR report and that they are lower than the national referential levels, which shows that there is optimised state of radiation protection for patients. The occurrence of concrete unusual radiation events at the department of NM in hospital Ceske Budejovice and their analysis revealed certain shortcomings in the process and the absence of security elements needed while holding radioactive liquid waste in storage at the hospital. It was necessary to find and implement such precautions, which will prevent similar type of events in future. The thesis will be handed in to the person tending to the radiation protection for the use of evaluation and providing the protection at the department of NM at the hospital Ceske Budejovice and to enable the documentation to be completed for the allowed activity.

Engagement of a rescue units to outer wrecking plan for nuclear power plant Temelin.
PLAŇANSKÝ, Jan
This work is focused on the involvement of the essential units of the IZS (the Integrated Emergency System) in a radiation accident, in another disaster or in a technical failure, damage or at a terrorist attack at the nuclear power plant in Temelín, particular ly with regard to the incorporation into the External Emergency Plan for the Nuclear Power Plant in Temelín, including verifications of their suitability and adequacy for dealing with emergencies. The current situation in the given area is analyzed in the analytical part of my thesis.. There are elementary terms defined there which relate to deploying the forces and equipments of the IZS (the Integrated Emergency System). The terms also relate to possible evacuation of people from endangered areas. There is also legislation concerning the processing of external emergency plans, concerning the settings of emergency planning zones. Also, there is a plan outlined, the plan about evacuation of people according to the External Emergency Plan of Temelin.
