Legal aspects of protection against radon
Fojtíková, Olga ; Damohorský, Milan (advisor) ; Sobotka, Michal (referee)
The aim of this diploma thesis is to present legal instruments used by the state to protect citizens from indoor radon and its decay products, to assess their effectiveness and to indicate possible pitfalls in their application. The paper first describes the radon issue from the perspective of natural sciences, introduces the unique Czech approach - the Radon Program, and describes handling of the issue by the state administration. The main emphasis is put on the development of related legislation, especially in the field of atomic and building law, where the state's approach to guidance levels is critically evaluated and where some recommendations for building management are mentioned. The legislation is also closely associated with the provision of state subsidies for anti-radon measures. Current developments are evaluated and options potentially leading to an improved effectiveness of this instrument are outlined. From a practical point of view, the paper is complemented by a case report based on private law and the related protection by civil law instrument.

Radon Study of a Sample of Chosen Municipalities of South Bohemia - Measurment, Results Analysis and Inhabitants´ Perception of Risk
NOVÁKOVÁ, Andrea
Radon Study of a Sample of Chosen Municipalities of South Bohemia - Measurment, Results Analysis and Inhabitants´ Perception of Risk The topic of my diploma thesis is radon study of a sample of chosen municipalities of South Bohemia - measurment, results analysis and inhabitants´ perception of risk. Czech inhabitants anxiety about radioactivity is usually focused on artificial sources of radiation, mainly on nuclear radiation. However, most of the irradiation of people is caused by natural radiation, espacially by radon. Within my diploma thesis I distributed 100 of detectors to measure volume activity of radon. After about six months I collected data to be processed. During the time of measuring I got know lots of people and I used the possibility to talk to them. That is why one of the aims of my thesis was to assess reaction of people to radon, to values of radon measured in their houses, people´s fears or indolence. I also tried to make the problem of radon easier to larger amount of inhabitants and I tried to make them understand this problem. I intended to inform people about results of radon radiation on human body. Main goal of my diploma thesis was to process data of volume activity of radon which were measured in the premises, to compare these data with the radon index of subsoil and to set a relation between volume activity of radon and other parameters as the age of the premises, contact with subsoil, tightness of windows, construction material used, and water source.

Relation between the level of Radon in the underlay and in structures in Central Bohemia
KADLECOVÁ, Zdeňka
Radon is a natural radioactive gas originating from a radioactive transformation of uranium. It penetrates the Earths surface from the geologic subsoil and cumulates in buildings where it can reach hich concentrations. Building material is also a radon source in resident premises. Water is another radon source. It isimportant to realize that the building materials of a natural origin as well as water supplied to the houses also gain a higher volume radon activity from the geologic subsoil. Hence my thesis particularly focuses on the building subsoil. My thesis that the beologic subsoil isa significant radon source affecting the radon volume activity in the objects, however, a high radon index of the eoloic subsoil does not necessarily mean that a high radon volume activity values will be measured in the building situated on the subsoil. It very much depends on the technical condition of the object and the way of its ue.
