Risks connected with the release of radioactive substances during transports to nuclear medicine workplace.
HELEŠIC, Jiří
This thesis deals with analysis and evaluation of risks associated with the release of radioactive materials during the transport, eventual accidents and radiation load handling throughout the all transport chain to nuclear medicine workplace in relation to current legislation and technical support for the transported substances. The theoretical part is focused on describing the current state of these issues, the reasons for using the radionuclides in the Czech Republic, their transport and description of legislation associated with that all. The research part shows the analysis of the health risks of people who might come in contact with the release of radioactivity. Then the analysis solves such consequences. In this work we mapped out the production and use of artificial radionuclides, modes of transportation and its technical security and handling of radionuclides during the transport. We also present the research in some possible accident during the transport. As well as emergency readiness and procedures of the Integrated Rescue System. In discussion there are throughout the commentary compared the following: determined state laws transport safety, radiation burden and risks of transports. In conclusion we found out that the level of legislation and the radiation burden is at an acceptable level. The work comes with its own proposal for improving transportation safety of radionuclides in the Czech Republic and that is to introduce the rights-of-way to vehicles described above.

The Current State of Destruction of Chemical Weapons in the World
HELEŠIC, Jiří
The subject of this thesis is a description, mapping and assessment of the present situation concerning the destruction of chemical weapons in the world. This thesis also attempts to predict the future development in this area. The introductory part presents the meaning of essential terms, the characteristics of chemical weapons, the classification of chemical warfare agents, the history of the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction, the description of this document and the subsequent formation and work of the Organisation for the Prohibition of Chemi-cal Weapons, its relations with the United Nations and an overview of the countries which stay outside the commitments of chemical disarmament. The goal of this work was to explore and evaluate the present situation concerning the destruction of chemical weapons in the world and to try to predict further develop-ment in this area. The methods used to map this problematic situation were to gather information from professional sources and involved organizations, then to compare the results of each country during their chemical weapons destruction in relation to their obligations to complete the liquidation. The outcome of this work was the confirmation of the hypothesis that despite the great efforts of the international society, despite the great efforts of general public and each country{\crq}s involved subjects at the national chemical weapons destruction in the world, this work has been succeeding very slowly and with great difficulties. To achieve complete disarmament will lie on the condition that countries will be subjected to effec-tive international control and that negotiations with countries which still stay outside the process of chemical disarmament will be hold even after the final deadline for disarma-ment in 2012.
