Assesment of radiation protection in DIAMO state enterprise
ŠIMÁČKOVÁ, Eva
The importance of possible consequences of radiation, possible health hazard of people and the radionuclide contamination of the environment requires securing radiation protection from the very start of any operation, where radioactive substances are being handled with. One of these fields is the uranium industry in which DIAMO, state enterprise, takes an important position, dealing with the extraction and treatment of uranium, effacing the impacts of mining, remediation and disposal. Findings in the field of uranium industry are primarily won in form of research of professional information sources. In the theoretical part of the work, historical data about the founding and development of the organisation DIAMO, state enterprise, about carried out operations and the affect on the environment are being listed. Furthermore, information concerning radiation protection, its history, principles and measures are being elaborated. On the basis of carried out analysis and gauging results the level of secured radiation protection in DIAMO, state enterprise, is being assessed. Comparing the analysis of currently valid legal regulations to the analysis of safety documentation worked out in DIAMO, state enterprise, the fulfilment of requirements of legal standards is being assessed. In areas affected with uranium industry (Příbram, Stráž pod Ralskem, Mydlovary) gauging the dose equivalent power consupmtion of gama radiation has been carried out. In selected sites water and soil samples have been taken to assess the concentration of radionuclides. The results of the research are being compared to the measuremet results from other sources. In conclusion it is possible to state that the results in the carried out research are comparable to the results of similar researches carried out in other countries.
Protection of workers, inhabitants and environment during mining and processing of uranium ore
PILECKÁ, Eliška
In the Czech republic uranium had been mined in Jáchymov (till 1967), near Příbram (1948 {--} 1991), in Okrouhlá Radouň in the south of Bohemia (1972 {--} 1990), near Vítkov in the west of Bohemia (till 1991), in Zadní Chodov (till 1992), in Dyleň (till 1994), in Hamr and Křížany near Stráž under Ralsko (till 1990), in Zálesí in Rychlebské Mountain and in many other locations. The mining of uranium influenced in considerable way health and quality of miners´ lives, and also lives of their relatives and up to now it still influencing quality of lives of people living near mining locations. Above all the uranium industry made irreparable changes in our country and the leftovers are up to now influencing the quality of our environment. That´s why there is a must to pay special attention to this area. Nowadays in the Czech republic there is registered around 3768 old uranium mines, out of it there is 2523 mining cannons which are obliged to be regularly controlled. The negative influences are marked as old burdens of already eliminated mining or modificating act on our environment or in some other way threatening public interests. According to the character of negative expression we distinguish mining burdens, it means negative influence of mining activity on stableness of the surface, and ecological burdens, it means negative influence on our environment. In my opinion a matter of uranium industry is very rarely known to the wide public. The main reason why is it like this can be the fact that in the period of main expansion of uranium industry in the Czech republic all the information connected to the research, mining or maintaining of uranium, were top secret. The second reason can be no existence of complete source of information that could be used for study purposes and the same time for informing general public. That is why this study should purvey such source.
