Effect of New Positron Radiopharmaceutical Shielding Equipment on Radiation Load Reduction of PET Centre Personnel.
MAŇASOVÁ, Olga
The bachelor thesis focuses on radiation protection of nuclear medicine personnel while using positron radiopharmaceuticals. The thesis is aimed at evaluating efficient and equivalent doses of PET centre personnel at Na Homolce Hospital where new shielding equipment with an activity dosing device was installed in 2006. Positron radiopharmaceuticals are characterized by emission of 2 annihilation gamma photons of high energy (511 keV) that are created upon interaction of a positron with an electron. Due to the high energies, radiological personnel receives higher radiation loads than upon application of common, particularly technecium-based radiopharmaceuticals used in nuclear medicine. The methodology consists in comparing efficient and equivalent doses before and after installation of the new shielding equipment. On base of results we can state that the doses to personnel were significantly reduced after installation of new shielding equipment. The doses were reduced by half during three years. New shielding is relevant from optimalization of radiation protection perspective. Statistical processing and graphic illustrations form part of the bachelor thesis.
Development of the Nuclear Medicine Field of Study (Didactic Programme)
BUČEK, František
The bachelor thesis explores the development of nuclear medicine in Czechoslovakia. The thesis recalls its present well-known specialists as well as founders of the field including the contemporaries Doc. MUDr. Bohuslav Vavrejn, Csc. and Prof. MUDr. Zdeněk Dienstbier, DrSc. whose memories were also used as resources by the author. The thesis describes the beginings of nuclear medicine in Czechoslovakia {--} the first application of radiopharmaceutical agents, creation of specialized centres, and becoming independent of the field upon approval of its first concept in 1964. This work also mentions problems initially dealt with by the field in terms of apparatus-based technical equipment, radiopharmaceutical agents and education. The foundation of the Czech Society for Nuclear Medicine is described, as well as cooperation with foreign institutions. Information on apparatus-based technical equipment import from abroad is included, particularly of the companies Nuclear Chicago and Picker, and also domestic production ranging from prototypes to serial production at research institutes or enterprises that included, for example, the Research Institute of Nuclear Technical Apparatuses Přemyšlení, TESLA Vráble, TESLA Brno and METRA Blansko. The bachelor thesis furthermore provides brief characteristics of radiopharmaceutical agents and a summary of present as well as no more used examination methods in nuclear medicine. Problems related to their initial use are described. Radiopharmaceutical agents were imported as early as in 1949 for the first time from France. Domestic production of radioisotopes began in Czechoslovakia at the end of the 50ies of the past century, located at Řež u Prahy. The thesis moreover outlines the concept of the field and legislation it is governed by. Individual types of centres are described, as well as educational requirements for the personnel. In conclusion, advantages of the field are assessed, its close relationship with new technical knowledge and development of apparatuses, such as the hybrid imaging devices PET/CT, SPECT/CT and molecular imaging. The thesis has also been adapted to an e-learning version where information contained in its written form are presented closer schematically and expanded upon for those interested.
