Předmětem bakalářské práce ?Radiační zátěž při screeningovém mamografickém

The subject of the bachelor thesis ?Radiation strain of a mammography screening test? is an evaluation of glandular dose for the determined thickness of breast tissue over the time period from January to March 2015. Data are obtained from an accredited mammography screening center P-P Clinic Kladno. The thesis is divided into a theoretical and a practical part. The theoretical part describes the origin and properties of X-ray radiation, its biological effects, units and quantities of dosimetry and radiation protection, protection against X-ray radiation. There is a chapter about mammography screening examination at the end of theoretical part. In the practical part, glandular dose for the determined thickness of a compressed breast (2,1 cm, 3,2 cm, 4,3 ? 4,7 cm, 5,1 ? 5,5 cm, 5,8 ? 6,2 cm, 7,3 ? 7,7 cm, 8,5 ? 9,5 cm) for the given time period are determined. Furthermore, the dependencies of determined thicknesses of a compressed breast on voltage, electrical quantity, compression strength and other are plotted. At the end, the obtained values areevaluated and compared with values from tests of long-term stability and with local diagnostic reference values. The thesis also discusses the protection of women during a screening mammography examination.
