Records of dose parameters in radiodiagnostic workplaces - contemporary state
MRÁZOVÁ, Monika
The theoretical part of the thesis deals with the characteristics of ionizing radiation. It explains the interaction of ionizing radiation with substance and cells. Attention is also paid to the mechanism of damage caused to the cells of the human body. It explains the basic principles of radiation protection. The paper describes the function of the ionization chamber, as the most common device used in dosimetry of ionizing radiation. A large section is devoted to formulas, which are routinely used to determine the effective doses. It explains basic indicator of obesity, body mass index, which has a significant impact on the dose received by a patient during examination. At the end of the theoretical part, hospital information systems and programs, offered by companies for record keeping of batch parameters at radiodiagnostic workplaces, are mentioned. An integral part is also the legislation which governs the registration of batch parameters, not only in the Czech Republic, but also in the European Union. The practical part of the bachelor thesis provides a comparison of two radiodiagnostic sites. Furthermore, an analysis of data provided by the database of Radiodiagnostic Department of the University Hospital in Plzeň - Bory was conducted in the practical part of the thesis. Due to the increasing number of computer tomography, 20 most dose-intensive examinations were selected. What examination it was and what could cause such a high dose was examined.
