The radiation exposure of employees of the former uranium ore processing plant MAPE Mydlovary.
NOVOTNÁ, Dana
In 1959, approximately 20 km to the north-west of České Budějovice a construction of a chemical uranium ore plant MAPE began. The plant operation started in 1962 and finished in 1991. The premises of the former chemical plant MAPE Mydlovary consisted of a plant in which uranium ore was manufactured and the manufactured material from uranium mines was stored in adjacent sludge lagoons. Uranium ore has never been mined in this area, neither in its surroundings. It has always been imported from uranium mines. Uranium was made from the ores by either acid or alkali leaching. Although this former uranium ore plant MAPE Mydlovary hasn´t been economically active anymore, it is nowadays one of the biggest environmental burden which results from ore mining and it's processing in the Czech Republic. Therefore, it is important to carry out remediation and recultivation works which are currently provided by the state enterprise DIAMO. DIAMO company, in fact, is also the owner of the former plant MAPE Mydlovary. During the operation of the former ore plant MAPE Mydlovary, about 1,100 employees took turns in the company. During the uranium ore treating and its consequent waste store in the lunge lagoons, employees of the plant were exposed to the effect of radionuclides. For this reason, my diploma thesis deals with the effect of radiation on employees of the former chemical plant MAPE Mydlovary and aims at the doses which the employees received while working in the plant. The data were gathered from October 2013 to April 2014 and contain figures for a period of 1963-1996. These figures were gained from personal dosimetrical files of the employees and these files were provided by the state enterprise DIAMO. The first aim of the thesis was to monitor the rate of radiation and to compare the gained values among individual employees of the plant MAPE Mydlovary. The monitoring of the effect of radiation was carried out from personal files of the employees and the measured values were put into tables of Excel programme. The values were then compared and I also used descriptive figures statistics. The doses at the employees were found not to exceed any dose limits. The second aim of the thesis was to evaluate the measured values at several groups of employees according to the type of the work they do. The division into individual groups was carried out according to the scale of received doses. It deals with a group of employees who worked at least for 6 months with dustiness, another group working in a sludge lagoon, another group of workers who were responsible for the main manufacture but weren´t exposed to any dustiness (according to the type of work, these people were then divided either into the first or the second sub-group) and also a group of other employees who had their own dosimeter- this group served as a comparative reference in a statistic research. The measures values were evaluated by a statistic research. For this type of research, we used a parametric testing and a so-called Fischer´s F-test, which was applied thanks the Statistics function in a table processor MS Excel 2010. For this test, we used the level of significance = 0,05. Through the statistic research, we have found out that the highest measured values appeared at the employees who were working in the main manufacture but without any dustiness. This group of people was ranked as the first group. The lowest amount of received doses appeared at the employees who worked in the main manufacture, without any dustiness and were put into the second sub-group. The hypothesis that the doses of the MAPE Mydlovary employees are different within the groups has been confirmed. The hypothesis that the doses at the MAPE Mydlovary staff didn´t exceed any dose limits for the staff has been confirmed as well. The hypothesis that the doses at the MAPE Mydlovary staff were different in certain groups was confirmed.

Observation of non invasive and invasive screening cerebral vessels from the radiologic assistants view.
NOVOTNÁ, Dana
The subject my thesis was ? Observation of non invasive and invasive screening cerebral vessels from the radiologic assistants view". In the theoretical parts I explore the disorder of blood - vessel in cerebral occurrence (CMP) and its diagnosis. It is about the acute illness caused by closure of some of the cerebral arteries and resulting in vapidity brain (ischemic) or bleeding to the brain (haemorrhage). It ranks among the most frequent causes death in developed countries. The practical part includes research of usage non invasive and invasive depict methods in brain and cerebral vessels diagnostics. I processed quantitatively the statistical data which I gained from the Radio-diagnostic Ward in hospital in Ceske Budejovice. The result of this emerges from superiority of non-invasive screening above invasive one. In the non- invasive depict methods in diagnosis of CMP most often uses computation tomography (68 %), which for a certainty will distinguish ischemic from haemorrhage. Magnetic resonance (7 %) is more sensitive method at ischemic diagnostics. Another method is the ultra-sonography (13 %), in which we can assess the level of stenos/occlusion screened vessel. As the only vice invasive methods is catetrizac angiography (12 %), which is considered as the golden standard in displaying the blood - vessel bed. Its advantage is the possibility to join endovascular intervention. The next aim was to compare the role of radiologic assistant during single screening. It was necessary to find common point in practical activities of the radiologic assistant at both types o screening and to show the differences in specific substance and the work demands.
