Comparison of risks of people occupationally exposed to ionizing radiation to people working in other professions
VORÁČKOVÁ, Marcela
The diploma thesis deals with the examination of risks impacting persons professionally exposed to ionizing radiation and the dangers posed by other professions. It is divided into a theoretical and practical part. The theory explains the concept of ionizing radiation and considers its sources. It also discusses the effects and subsequent exposures and protection. There is a brief chapter on workplaces with radiation sources. The practical part is designed in the form of qualitative research. The aim was to compare the risks in ccupations in which people are exposed to ionizing radiation with the risks of persons in other professions. During the research, I determined radiation doses, radiation risks in employees, the number of expected deaths, the cause of exposure, the consequences and the possibility of preventive measures. I also examined mortality in other selected professions. I determined the number of deaths caused by cancer and other diseases and injuries. At the end there are three interviews with the physicians of Prague hospitals and a nuclear power station providing information on this issue from their many years of experience. In the discussion part, the results are being compared and evaluated. The risks of death of irradiated workers, the benefits they actually receive, have been shown to be low, and their positions are therefore considered safe compared to other professions. For other jobs, on the other hand, a high number of deaths during working hours has been ascertained. In the case of the risk of death of irradiated workers with "tolerable" doses, the values are already higher in comparison with other professions. Despite the benefits of the work, its research may be negatively affected by a small selection of professions - not all existing positions have been included, such as teachers, bricklayers, train drivers, game carers and others. Therefore, it is important to further nvestigate the risks and discuss the correct setting of limits for radiation workers.
